XAT Racing

XATRacing.com is now offering a 2JZGTE (also fits 2JZ-GE) torque plate for those that want to properly hone the cylinders on the 2JZ-GTE engine. It also fits the 2JZGE non-turbo blocks, as well as the 1JZGTE motors.

Any serious engine builder will tell you, especially given the length of the inline 6 engine, that you need a torque plate in order to provide a similar stress pattern on the block that it experiences with the head on the block.

Some builders even go as far as putting an old head gasket between the block and plate, then go through a standard Toyota pattern for torquing down the bolts.

This is a precision machined torque plate, manufactured out of 2.0" (50.8mm) thick 6061 T6 aluminum (precision CNC'd by a large aerospace machine shop). Aluminum is chose as it best replicates stress and strain coefficients of expansion during torquing that the factory aluminum head does.

It has an overbore that will allow for the largest hone/bore possible, so if you are building a stock bore or big bore, it isn't an issue.

The bolt through-holes are clearanced for 1/2" (.500") head studs, which allows you the flexibility to run a factory diameter or 1/2" diameter head stud, all according to the factory head stud location. It is shipped in a sturdy container for protection.

People charge up to $800 for these units, so we thought we can do it better and for less.

You can expect it to ship next day typically, as we have one on the shelf at all times!

These are available for shipment outside the USA if required. Please email sales@xatracing.com for a freight quote.

A torque or honing plate is critical when doing the hone/bore process on any 2JZ engine build, especially those that will be running 30psi+ of boost and those running ARP head studs. Performance studs are typically torqued at much higher values than standard OEM studs, which causes a deflection in the cylinders if not using a torque plate.

Machining Note: Prior to the machining process the torque plate should be secured to the block using the same amount of torque you intend to apply during final assembly of the head to the block. We are also offering a rental service to use the ARP head studs that can be shipped with the plate. If you go this option, you will also be charged $15 weekly to rent them, which we will subtract from the deposit once it is returned to us

This listing includes all of the parts to assemble a stainless braided clutch bleeder/drain hose kit for our transmission adapter kits not using a Nissan 6 speed (CD009/JK4/1EA,etc.). Choose your desired length. 10" will just get you by, but longer hoses will let you bleed the system without laying on your back under a car in an uncomfortable and potentially dangerous spot. This kit fits the T56 style throw out bearing specifically 

Please keep in mind you will need to drive out the retaining pin holding the "GM quick disconnect" style fitting on the feed side of the TOB, keep the pin, and reuse it for the replacement fitting.

Throw out bearing not included with base kit

Includes:

• 36" (or optionally up to 48") stainless steel braided clutch hose
• Replacement adapter fitting to convert to AN line
• Banjo bolt, fitting, and crush seals to connect to clutch master cylinder (M10x1.0, most Japanese applications)

Nobody else makes these. So why wouldn't we?? XAT now offers billet main caps for the latest Toyota V8s! If you're looking to build the baddest UR on the planet, look no further. Whether you're building a VIP LS, a quick GS, a rock crawling GX, or a beastly Tundra, Land Cruiser, or Sequoia, we can help build and assemble your motor for you to handle however much power you are aiming for! We've installed these on a few built engines now, and we're looking forward to continuing that trend!

Keep in mind, as with all main cap replacements, you will need to have your engine line bored after installing these.

Quick version of what you'll need:

• T56 style throw out bearing
• Pilot bushing adapter (included)
• Nissan 6 speed (CD001, CD003, CD005, CD008, CD009, CD00A, JK41A, JK41B, JK40C, 1EA0A, or 1EA0B)
• Our flywheel (no other ones will work)
• 300ZX TT clutch Z32 twin turbo
• 1UR removeable bellhousing with 12 bolt trans-side flange

Does NOT require a ring gear! Bolt up your factory flex plate! Uses any off the shelf Z32 Nissan 300ZX TT single disc clutch with any 350Z/370Z transmission application!

Pulley for UZ setups using the replaceable middle/center idler bracket instead of a hydrofan setup

Not sure if this is the right pulley for you? Put your application in the order comments, or email us before your order and we'll get you taken care of!

Anyone looking to turn their UZ V8 into something EXTREME should strongly consider a turbo setup! The biggest issue with "1UZ turbo kits" (or any UZ turbo kit) is chassis fitment. With every car and truck having different clearances, there's not a "one size fits all" turbo kit. Intake and exhaust piping will be unique to each setup.

Fortunately we have a solution to help get you started! You'll need to finish the rest of the plumbing on your chassis with the engine and turbo(s) mounted. Base headers are left open so you can either weld turns/transitions or your own flange. Optionally, we can weld 44mm v-band flanges to the end, so all you need to do is figure out the rest of the piping.

With this setup, you can mount the headers on either side. They are fully reversible! The most common solution is to run a single or twin turbos up front with the manifolds pointing forward. Remote mount turbos are also an option.

• All stainless construction
• Schedule 40, 304 stainless piping
• 1/2" thick header flanges
• Hand made in the USA, in house

Please note these are made to order so there might be a slight wait time. Although we can take custom requests, we cannot promise fitment. 

XAT has been building Toyota/Lexus UZ V8s and developing new parts for almost 2 decades for customers worldwide. We pride ourselves with taking the time to correctly assemble and rebuild every engine, knowing them inside and out. We also are excited to build more and more of these for boost, as we feel a manual transmission and a turbo or supercharger are what these engines really respond best to.

Every engine gets hand built to order. Not everyone has the same goals or budget in mind, so we have built everything from mild to wild!

You will need to send us your engine, or we can supply a core. 

Our "base" engine build handles 800 HP reliably, but we do have a variety of options that you should also consider. If you're not sure if you want them, keep in mind that it's much easier to spend a few extra bucks while we have it and it's apart, than it is to go back in later and add these parts!

Base build includes fully assembled engine, ready to drop in:

• Eagle ESP rods, optionally BC ARP2000 rods
• JE or CP pistons for high compression N/A or low compression boost
• All new timing parts (belt, tensioner, billet tensioner bracket, pulley, water pump)
• ACL rod/main bearings, OEM thrust washer
• Block honing with torque plate
• Hot tanked engine
• XAT modified high performance oil pump
• Ported intake/exhaust ports
• Valve job
• ARP head studs
• ARP main studs
• Heads bolted to block, timing set
• Valve lash set with shims
• New valve stem seals
• New valve locks/keepers

Every engine shipping from us also gets crated in ISPM 15 certified wood crates for international shipment. Your investment needs to be protected, and this is included in the build price

Shipping is not included, you will need to reach out to us with your location and we can get shipping quotes to your address!

Ask us about additional "white glove" service options to really make your built engine stand out!

XAT Racing is now offering a UZ engine torque plate (fits all 1UZ, 2UZ, and 3UZ engines) for those that want to properly hone the cylinders on their Toyota/Lexus V8s. It fits all UZ engines with factory sleeves. Any serious engine builder will tell you that you need a torque plate in order to provide a similar stress pattern on the block that it experiences with the head on the block. Some builders even go as far as putting an old head gasket between the block and plate, then go through a standard Toyota pattern for torquing down the bolts/studs. This is a precision machined torque plate, manufactured out of 2.0" (50.8mm) thick 6061 T6 aluminum (precision CNC'd by our own machine shop). Aluminum was chosen, as it best replicates stress and strain coefficients of expansion during torquing that the factory aluminum head does. It has an overbore that will allow for plenty of room for honing and boring as possible, so if you are building a setup with stock or slightly larger bore, you won't have an issue. It is shipped in a sturdy container for protection. These are quite possibly the only ones on the market anywhere, so instead of charging up to $800-plus for these units, we thought we would bring it to the market for a reasonable price!! You can expect one it to ship next day typically, as we have one on the shelf at all times! These are available for shipment outside the USA if required as well! Please email Andrew@XATRacing.com for a freight quote. 

A torque or honing plate is critical when doing the hone/bore process on any engine build, especially those that will be running a boosted setup and ARP head studs. Performance studs are typically torqued at much higher values than standard OEM studs, which causes a deflection in the cylinders if not using a torque plate.

Please note the $78 rental is for 1 week, which starts from the day you receive the plate. If you need it longer, we will prorate the charge out of the refund for each week after. You may be better off purchasing it outright if you end up needing it for more than a week or two.

This will fit all UZ engines, VVTi or non. We keep the factory oil pump in stock, so we can typically ship out a modded pump next business day!

Higher horsepower means more oil demand. When you're running twice or three times the stock power output, you absolutely have to be sure your engine is getting lubricated everywhere it needs to! Especially if you have an aftermarket oil cooler to keep oil temps down!

What does XAT do to bring you options for a better oil pump? We take a brand new OEM 98+ Toyota pump, remove all hard edges, radius all corners, enlarge the front main seal drain, and shim the pressure relief valve to give more max PSI. Make sure you get a quality oil pump for your engine, from the professionals at XAT!

In the pictures, you can clearly see some the upgrades we have made. Check out pictures where you can see the oil pressure relief piston polished for smoother operation, and more consistent oil pressures.

There's plenty we do to greatly improve the oil flow without trying to "reinvent" the stock setup! The factory oil pump works well for factory applications, but there's clearly plenty of room for improvement, as we show here.

Take a look at the nasty hard edges that oil goes through, thanks to mass production. Get the added insurance of a much better oil pump from the professionals at XAT Racing!!

In another world first, XAT brings a solid manual swap option to the extremely common V6s made throughout the 2000s-2010s that replaced the aging MZ series. This includes the Tacoma, Tundra, 4Runner, FJ Cruiser, some overseas Land Cruisers, Avalon, RAV4, Camry, Highlander, Venza, Sienna, RC350, RX350, IS250, IS350, GS350, and other overseas vehicles. Please note that this is the adapter to convert the engine to manual, and much more custom work would be needed to convert the rest of the car/truck over. This is also specific to longitudinally mounted engines (RWD/4WD) and not transverse FWD engines. You will re-use your factory auto bellhousing for the swap, which is not included. This is a brand new part! If you have any questions, please contact us.

PLEASE NOTE THIS IS A DIY PART. YOU WILL NEED OTHER THINGS SUCH AS FLYWHEEL AND CLUTCH TO BE FIGURED OUT ON YOUR END. YOU MAY BE ABLE TO USE A 1GR OR 4GR FLYWHEEL, BUT WE MAKE NO GUARANTEE OF FITMENT. YOU MAY ALSO NEED A 12 BOLT BELLHOUSING FROM AN IS250 FOR INSTANCE

Pictures show the RWD K17 type caliper being used. The AWD N18 caliper has the same bolt pattern, but the caliper sits taller on the rotor. As such, the N18 version will not work with the IS-F rotor. You'll need to stick to the K17 type.

In our continuing support of Lexus performance products and the UZ platform, we have finished this set of ZINC CHROMATED brackets to mount LS460 / LS600h or LS500 brake calipers to any GS300, GS400, GS430, SC430, and many others!

These brackets are ideal for those DIYers that are looking for an inexpensive option for brake upgrades. You keep your factory brake lines in this bolt-on solution; all you need is a set of front 2007-2018 LS460, LS460L, LS600h, or even the new 2019+ LS500 fixed 4 piston brake calipers, LS460 fitment pads, and a set of 2008-2014 IS-F 14" rotors!

Although the roll center adjusters aren't mandatory, they provide a bolt on solution. You do not have to run them, though if you do not, you may need to modify the mounting hardware. They will improve the suspension geometry on lowered cars at any rate, so we highly recommend them.

Please note that the LS460 does NOT use 5x114.3 rotors, so you will NOT be able to bolt on the LS460 rotor. We do not have fitment confirmation on the larger LS460 F-Sport 6 piston Brembo brakes, though they may also fit when used with larger rotors

Additionally, you will most likely need 18" wheels to fit over these. The only 18s we have found to not fit so far are some Enkei RPF1s. We cannot make any promises on what else will not fit, however every other 18" wheel we have tried does fit over these brakes, including factory X-Runner wheels, Enkei NT03+, G35 Ray's wheels, etc.

Brackets fit:

☼ 1992-2005 Lexus GS300 / Toyota Aristo JZS147, JZS160, JZS161

☼ 1998-2000 Lexus GS400 / Toyota Aristo UZS160

☼ 2001-2005 Lexus GS430 / Toyota Aristo UZS161

☼ 2001-2005 Toyota Crown Majesta 1UZ

☼ 2001-2010 Lexus SC430 / Toyota Soarer UZZ40

☼ 1997-2017 Toyota Century V12 GZG50 

☼ 1989-2000 Lexus LS400 / Toyota Celsior UCF10/UCF11 and UCF20/UCF21

☼ 1992-2000 Lexus SC300/SC400 / Toyota Soarer JZZ30, JZZ31, UZZ30

☼ 1993-2002 Toyota Supra JZA80

WE HAVE OTHER BRACKETS TO FIT IS300/CHASER/MARK II/CRESTA/CROWN HARDTOP AS WELL!

You will receive 1 pair of brackets to mount both front calipers, as well as mounting hardware. Please note that we normally stock the brackets and rotors, however it may take 1 week to ship the calipers. 

We have FINALLY released a rear kit to go along with this front kit! Our rear kit uses radial mounted LS430 (not LS460) rear calipers and Supra TT rear rotors. PLEASE NOTE FITMENT DIFFERS FROM THE FRONT KIT. NOT ALL OF THE ABOVE CHASSIS' ARE SUPPORTED. Keep in mind these are designed for off road use only and professional installation is required. We have been driving on these kits for years, but use at your own risk.Check out the rear kit listing here! 

Please note this kit is a direct fit for rear sump engines. If you have a front sump application (IS300, GS300, Crown, S13, S14, etc.) or are using the extended oil drain, you will need to shorten the drain and use a new fitting for the hose end. We have that as a dropdown menu option

1JZ/2JZ single turbo oil line kit for T series turbo, custom made in house! Includes everything pictured plus gasket for the turbo drain, 12mm to -3 adapter for the block oil outlet, and a rear oil outlet block-off. This means a -3 oil feed for the turbo and a -10 drain line. We recommend the -4 version for Borg Warner AirWerks turbos (S300, S400, etc.) as well as the EFR series. The EFR series of turbos has a -4 oil inlet built into the CHRA, whereas Precision turbos typically are over-oiled with -4 lines and should run a -3 instead.

This is the highest quality kit on the market, utilizing aircraft grade hoses, and performance custom built 6061 T6 aluminum flanges.

Since we do not use crimp-on fittings, we can also easily alter the length of the drain! This is ideal for those that want to make life easier for themselves and run an extended turbo oil drain. If you order the extended drain, we will make the drain line accordingly.

APPLICATION:: 2JZGTE engine (all). Standard bore, .020", 040" (86.0, 86.5, 87.0 bores). 2JZGE (non-turbo) ALL. Standard bore,.020", .040" (86, 86.5, 87.0mm bores).

We have done it again! Since 2009 XAT has worked to bring into service the much desired 4-piece metal head gasket for the 2JZGTE engine with a true STOPPER layer. As you know the factory 2JZ head gasket is quite robust, but there is nothing that holds boost like the STOPPER designs. The problem has always been that GReddy and HKS had a lock on this market and could charge what they want! We've been using this gasket in every 2JZ engine we've build for over a decade

NOT ANY LONGER! We have available immediately modern 4-Layer Metal Head Gaskets 1.3mm thick with the proven STOPPER layer at an affordable price, and NOT made in an Asian country!

Explanation for the difference between the 3-layer version, and this 4-layer, and the advantages. The 4 layer version allows for thinner layers, far improving heat dissipation as there are more layers to absorb the heat. Rigidity, durability and thermal transfer characteristics far exceed standard MLS head gaskets.

How does the STOPPER layer work? The stainless steel .015mm thick STOPPER layer features a precision "fold" which encircles the cylinders creating an additional load point for the combustion chambers. In English??? The STOPPER layers STOPS combustion gasses from escaping in the best means possible, period!

What about the top and bottom layers? They are active control layers are micro-embosses pre-coated steel that micro-seal engine fluids at the most disciplined level possible.

The center layer? Made out of steel, precision manufactured with the main purpose to set an accurate overall thickness tolerance for the entire gasket. This ensures even distribution of pressure in the most accurate means possible.

Our head gasket is being used by major 2JZ engine builders all over the USA, Middle East, Australia, South Africa, UK, Canada, New Zealand and even in the former Soviet States and in many nations in Europe!! Used on the ProShop 8.1 second drag Supra out of Abu Dhabi, as well as multiple other 8 second cars worldwide!

Contact us for a shipping quote! Price does not include shipping to or from us. Cylinder bore and block decking will be determined by the condition of the block being used.

Why spend an extra $1,000-$3,000 more for a built short block, when we offer the exact same components (lets face it, everyone uses the same components) and many of the same machine shops everyone uses?

Truth be told, not a single major Supra parts business has its own machine shop tools. Not one, us included. What we do have are machine shops (2) that have been machining 2JZ motors for years, so once we understand the application of the engine (race only, fast street car, etc), then we machine the block with the tolerances required.

We assemble and meticulously build each motor in-house. All our tolerances are checked and then double-checked. Crank has already been confirmed rotationally during high-speed final balancing.

Pistons weighed, rods weighed. We cannot describe everything we do in a simple listing, but suffice it to say, it's a comprehensive build. Rings are hand filed, and all torque settings done using SnapOn instruments kept in spec. You end up with a professionally assembled engine ready for install.

2JZGTE/2JZGE engines that have been prepped for power with forged pistons, ARP hardware, micro-polished and chamfered OEM crankshafts, machined using state-of-the-art equipment, and custom 2JZGTE specific billet torque plates are what our customers demand. We can do 1JZs, too!

On top of this, Supra owners want to make sure the engines are proven, cost-effective (budget minded) and available for quick turn around times.

Your wish is our desire. The XAT RacingStage 1+ race prepped 2JZGTE shortblock starts complete at well under $6000!

We start with a thoroughly inspected 2JZGTE bottom end, which is inspected and cleaned, prior to being selected for fitment of quality components.

The engines are then machined using a custom built billet torque plate (we have our own torque plates), so the engine stays "square and true" during machine work and prep for new forged pistons. Why we use a torque plate is explained in this video (same holds true for our setups, if not more so). 

Ask us about additional "white glove" service options to really make your built engine stand out!

Our adapter plate is the best option for adapting your engine to a T56. Here's why:

• Reuses your extremely common/easily sourced J2 bellhousing from your 1JZ or 2JZ engine
• Billet CNC aluminum plate for superb strength and minimal weight
• Less expensive than a full bellhousing replacement, with less shipping cost
• Direct bolt on adapter, no cutting or welding required

Because of poor fitment of other manifold options on the market, we decided to develop a new exhaust manifold specifically for our JZS155 hardtop Crowns! This manifold puts the turbo in just the right position to not interfere with the throttle Y-pipe that goes over the engine, so you can retain the stock intake manifold still. Larger turbo setups may require further modifications, which you can expect with larger turbo setups anyways.

304 stainless steel, 2mm thick runners, 1 5/8" runner ID and a 3 year warranty!

Please note that while we try to keep the T4 version in stock, there may be a 4-6 week wait time for them to be custom made.

This fits 1JZGE VVTi heads, but not 1JZGE non-VVTi heads, which are unique and do not have an interchangeable bolt pattern. Turbo and turbo kit not included with this listing, but we can build you one!

Wastegate piping is included, however the base manifold does leave off the flange for you to weld the matching flange for your wastegate. We also keep in stock flanges for the most popular wastegates, so we can include and/or weld that up for you!

Quick version of what you will need:

• T56 style throw out bearing
• Our flywheel (no other ones will work)
• 300ZX TT clutch
• UR serviceable bellhousing with 12 bolt or 14 bolt trans flange
• Pilot bearing (included)
• T56 transmission

As we break into the new era of 1UR and 3UR engines, we have begun development on 6 speed manual swap options. We've developed an adapter plate specific for the UR automatic bellhousings to convert to a manual transmission, in this case the popular Tremec T56 Magnum! This specific plate works on all UR engines, however you will need the matching bellhousing that has the 12 or 14 bolt bellhousing-to-trans-case pattern. The only 1UR bellhousing this does not bolt to is the Land Cruiser/LX460 200 series 1UR-FE with the same 14 bolt pattern as the 3UR engines.

This billet aluminum adapter plate reuses your automatic UR bellhousing. Not all UR engines had a replaceable bellhousing, so you may need to source one from a GX460 or other Toyota/Lexus URs for instance. 

Our flywheel for T56 transmission applications uses the same one as our UR-to-Nissan 6 speed (commonly referred to as the CD009). You will need our in house flywheel, which bolts to your factory flex plate. We are able to keep costs down of this custom billet part by reusing the factory flexplate for a ring gear, instead of supplying an aftermarket one that does not work any better than the factory parts do. T56 transmission not included.

Please note the 1UR-FSE and 1UR-FE 4.6 engines uses a different flywheel than the 3UR-FE and 3UR-FBE 5.7 truck engine. You will reuse your factory flex plate for the ring gear and factory starter engagement.

The T56 style throw out bearing is also used with these kits. These are relatively inexpensive, which helps keep swap-cost down. We also offer a Quarter Master TOB as an option for a higher quality long term investment. 

Twin disc/multi plate clutches will require the use of the QM TOB, it is not optional on the 7.25" and 8.5" twin disc clutches we offer. The QM TOB also requires a Tilton quill tube (input shaft sleeve), which is included as well as the bleed line that is needed if the QM TOB option is selected.

Looking for a clutch for this adapter plate? 

Quick version of what you'll need:

• T56 style throw out bearing
• Pilot bushing adapter (included with transmission adapter)
• Nissan 6 speed
• Our flywheel (no other ones will work)
• 300ZX TT clutch
• 3UR serviceable bellhousing with 12 bolt trans flange

Why isn't everyone running a 3UR?! After tearing one down and analyzing the engine top to bottom, we've really come to appreciate the level of engineering that has gone into these engines. It's no wonder they were made for over 15 years! We feel they're extremely underrated, and they also respond especially well to supercharging.

XAT has been building 3URs and developing new parts for years for customers worldwide. We pride ourselves with taking the time to correctly assemble and rebuild every engine, knowing them inside and out. We also are excited to build more and more of these for boost, as our daily driven Whipple supercharged Tundra has become an entirely different beast with forced induction.

Every engine gets hand built to order. Not everyone has the same goals or budget in mind, so we have built everything from mild to wild, including an all out 6.8 liter bored and stroked version!

You will need to send us your engine, or you can use one of our supplied cores. We have a few in stock!

Our "base" engine build handles 800 HP reliably, but we do have a variety of options that you should also consider. If you're not sure if you want them, keep in mind that it's much easier to spend a few extra bucks while we have it and it's apart, than it is to go back in later and add these parts!

Base build includes fully assembled engine, ready to drop in:

• BC ARP2000 rods
• Manley pistons, 10.0:1 compression ratio
• Full OEM new engine gasket kit
• All new timing parts (chain, guides, tensioners, etc.)
• ACL rod/main bearings, OEM thrust washer
• Block honing with torque plate
• Hot tanked engine
• XAT modified high performance oil pump
• Ported intake/exhaust ports
• Valve job
• ARP head studs
• ARP main studs
• Heads bolted to block, timing set
• New valve stem seals

Every engine shipping from us also gets crated in ISPM 15 certified wood crates for international shipment. Your investment needs to be protected, and this is included in the build price

XAT 1UZ-FE 2UZ-FE 3UZ-FE Torque Hone Plate XAT EXCLUSIVE

THERE MAY BE A SIGNIFICANT DELAY ON THIS AS CALIPERS ARE OFTEN DIFFICULT TO SOURCE. Please plan your build accordingly, as it may take weeks or months to fulfill an order

Complete bolt on kit for your Mk4 Supra or first generation Lexus SC! Includes either front and rear or just fronts. Calipers come in red, though you can always have them powdercoated locally! You WILL need to clearance the caliper around the mounting bolts (invisible when installed) to mount them, so make sure you do this before having them powdercoated if you go that route. We do have a walkthrough that can be supplied with the kit as well.

These are actual genuine large sized Brembo calipers and have had terrific results from our customers!

Includes:
☼ Complete Loaded Calipers
☼ Mounting Hardware
☼ Rotors (360mm front, 345mm rear)
☼ Stainless braided brake lines
☼ StopTech/Centric semi-metallic pads (others available upon request)

Rear kits will also retain use of the factory e-brake. You will need at least 18" wheels for these, and some minor trimming will be needed on the caliper. Keep in mind that the Supra was never originally designed to use these calipers, and the only Brembo set that requires no modification whatsoever is discontinued. A great alternative to kits that are 2x as expensive.

Please contact us with any specific questions/requests and we would be happy to help out! Please also contact us if you need expedited shipping as well. The automatic shipping calculator might not give the correct estimate for expedited shipping

Brembo would also like to let you know they do not recommend using repainted or re-coated brake calipers, as they no longer meet Brembo's operating standards: https://www.brembo.com/en/company/news/5-reasons-not-to-use-repainted-brake-calipers-brembo

If you are building a bullet proof UZ series V8, you will need the ARP Stud kits found here. If you're building a HIGH HP UZ, you'll definitely need this ARP2000 version! We now offer an ARP2000 version of our popular UZ head stud kit for those looking to push the limits. High HP guys that are looking for the absolute best need not look further! Our Genuine ARP2000 Main Stud Kit includes all 20 Main Studs, 10 Side bolts (1UZ and 3UZ engines have 6 bolt mains!), 20 nuts, 20 washers, and 2 packs of ARP assembly lube to assemble one complete engine. Each ARP2000 main stud needs to be torqued to 70 ft/lbs Our Genuine ARP2000 Head Stud Kit includes all 20 Head Studs, 20 nuts, 20 washers and 2 packs of ARP assembly lube to assemble one complete engine. ARP2000 head studs need to be torqued to 70 ft/lbs When racing professionals in NHRA, IHRA, NASCAR, and Formula 1 competition need bullet-proof fasteners for their high-performance machines, they turn to one company: ARP. Since 1968, Automotive Racing Products has been engineering and perfecting bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, transmissions, and more. ARP uses only top-quality materialsfar above the usual aerospace quality others settle forin a highly exacting manufacturing process to create fasteners with the strength and durability to last race after race. XAT Racing leads the world in Toyota/Lexus V8 parts! Vehicles that came with these engines include SC400, GS400, LS400, SC430, GS430, LS430, GX470, LX470, Land Cruiser, Tundra, Sequoia, and Celsior, Soarer, Aristo, and Crown. Please note that you may have to shave 2 of the head studs down for each head, about 10mm, for the scissor gears that drive the cams. This is most commonly an issue with non-VVTi 1UZs

Customers outside the USA: please contact us for a shipping quote to your location. The automatic shipping calculator might be waaaay too much.

If you are building a bullet proof UZ series V8, you will need the ARP Stud kits found here. If you're building a HIGH HP UZ, you'll definitely need this ARP2000 version! We now offer an ARP2000 version of our popular UZ main stud kit for those looking to push the limits. High HP guys that are looking for the absolute best need not look further! 

Our Genuine ARP2000 Main Stud Kit includes all 20 Main Studs, 10 Side bolts (1UZ and 3UZ engines have 6 bolt mains!), 20 nuts, 20 washers, and 2 packs of ARP assembly lube to assemble one complete engine. Each ARP2000 main stud needs to be torqued to 70 ft/lbs 

Please note that the 1UZ non-VVTi version will have 10 studs that are 8740 instead of ARP2000, and the side bolts will also not be ARP2000. This should not have any adverse effect on performance. The 8740 studs get torqued to 60 ft lbs instead

LISTING IS FOR HEAD STUDS FOR 1 COMPLETE ENGINE, BOTH HEADS! Head studs need to be torqued to 60 ft/lbs 

XAT Racing leads the world in Toyota/Lexus V8 parts! One of the most important and integral upgrades when squeezing more power out of the UZ engines is to go with better fasteners. We've developed a custom kit (not just reused other kits) to give your V8 a bit more room to work with safely, especially if you plan on boosting it!

What's important about these ARP studs? The factory bolts are torque to yield, meaning they are purposefully stretched after one use, and cannot be safely reused. These ARP studs can be used countless times in multiple engine builds, provided they are not stretched.

Studs also give you a more solid clamping force over bolts. Check out the excerpt from ARP's catalog for an explanation we have in the pictures! 

For those looking to run more boost, more power, or just want added safety, we have also developed an ARP2000 version of our head stud kits! The added tensile strength of the ARP2000 material lets you torque the studs down further, giving you even more protection from lifting the heads and/or blowing a head gasket.

Please note that you may have to shave 2 of the head studs down for each head a small amount for the scissor gears for the cams. This is most commonly an issue with non-VVTi 1UZs

Ever have an engine come apart at high RPM? Well, we haven't. At least, not due to rotating assembly vibrations. We've partnered with the biggest name in the industry yet again to release an 800+ HP capable harmonic balancer for all 3UR-FE and 3UR-FBE 5.7 liter "big block Toyota" engines. That includes Sequoia, Tundra, Land Cruiser, and LX570.

You will have to grind down the factory washer for clearance on the factory crank bolt for this to fit properly. We typically use a belt sander and hold it at a 45* angle to shave the OD. There is no other easy option for this

Please note this does not work with 6 rib belt 1UR engines. We are still working on a solution for the small block 4.6.

We now stock a special 7" overdrive diameter pulley for high boost applications with a supercharger! A larger pulley while keeping the included blower pulley the same size will spin the blower faster and make more boost. WE STRONGLY RECOMMEND NOT DOING THIS UNLESS YOU HAVE A BUILT ENGINE WITH AFTERMARKET RODS AND A SOLID TUNE. 

XAT strives to keep the Supra and JZ market fresh, and our Royal Chamber manifold is no different, having been launched in 2016. We now have years of feedback with dozens of installs around the world, the consensus is that the manifold flows in a linear fashion from cylinder to cylinder and provides more volume of boost-compressed air as well at an unheard of value.

Couple this with excellent features, stunning workmanship and you have a winner on your hands. Similar to other billet runner designs, this manifold offers the same great looks and performance at an affordable price!

Need it for a 1JZ-GTE? 2JZ-GTE VVTi? 2JZGE? We have you covered!

Yes, we ship internationally and are glad to do so. Select your region from the drop-down menu. If you don't see your country, don't worry, send us an email and we will get you a shipping quote.

As a buyer you will receive:

(1) XAT "Royal Chamber" JZ Intake Manifold (1JZGTE, 2JZGE, or 2JZGTE)
(1) Fuel rail anodized, 14mm injector size (injectors not included)
(1) 90mm throttle body, made for Toyota GTE TPS
Hardware for installation

Please note that you will have to relocate the power steering reservoir in most cases (we have bolt on solutions for this), and the fuse box typically has to be moved and re-mounted. The factory throttle cable will also not work with this manifold, so you'll need a custom length one. We now also have a dual fuel rail version for those looking to run high HP and 12 injectors!

If you have any questions please contact us prior to purchasing. Thanks for shopping with us!

One of the few carryover parts from the JZ engines! This means this alternator pulley will fit all 1JZ, 2JZ, 1UZ, 2UZ, and 3UZ engine alternators. This pulley has the same diameter as stock as well, but looks much better! Billet CNC machined pulley with our brand laser etched into the sides. 

Looking to delete that power steering pump and go electric? We've got you covered! These are custom made, in house designed, machined in the USA (as all of our products are), and ready to go.

Included is the billet piece and the pulley. This will bolt up to your factory power steering mount bracket. The size of the pulley is the same as the top idler pulley. Depending on what else you may be doing, you may need to use a different belt size. Best way to check size needed is to use a piece of string to route around and measure the length needed.

Please select if you have a VVTi engine or non-VVTi from the dropdown. If you're not sure which version you need, feel free to take pictures and measurements and reach out to us!

You will need to shorten 2 of the bolts for installation as well. 

For 2UZ fitment, you WILL need to source a 1UZ VVTi or 3UZ mount bracket for this

Our "standard" UZ Toyota V8 build has no problem holding 800 HP, but we also have options to do well over 1000+ HP!!

Standard short block build includes:

• Full inspection of all critical measurements 
• Eagle rods with standard ARP 8740 bolts
• CP/JE forged pistons and rings (optional upgrades include ceramic coated piston face, moly coated dry skirt coating, bigger/stronger wrist pins, etc.)
• ACL rod, main, and thrust bearings
• ARP main studs
• Hot tank/vapor blasted block
• Brand new OEM or UPGRADED OEM oil pump
• Fully assembled, fully machined, and fully balanced! 

We also offer upgrades over the above parts!

We've been doing UZs for well over a decade, so we know these engines inside and out. We also know the importance of being able to customize your build and have the flexibility to run exactly what your budget allows.

Before pistons are ordered, we inspect the block's condition and advise what sized pistons will be needed. This does not change the price, however you ideally will want as much cylinder wall thickness as possible, as that will hold power better, and it will give you room in the future to rebuild again if need be.

We also always use our in house torque plate to properly stress the block as with a head installed

Unlike other builders that order the pistons and drop them in, we make sure each bore correctly matches up with each specific piston! This is done to maximize fitment and sealing, which leads to more power and less blow-by.

Please note this does not include the core charge. We can easily source an engine for you, or you can send yours to us for building. We've built countless engines over the years and shipped them worldwide, including multiple builds making more than 1000 horsepower. 

This listing is for a build short block, which does not include, long block assembly, setting the cam timing, installing the heads, setting the valve lash, head studs, valvetrain, etc. We can do a full build including those things as well, just let us know what your goals are and budget is!

Contact us with your address for a shipping quote! Listing does not include shipping price to or from us. We can assist with the logistics and having that taken care of.

As it turns out, the UCF10 and UCF11 1989-1994 1UZ Toyota Celsior has its own dedicated pulley for the hydrofan. This is not interchangeable with the USDM LS400 pulley, this is for JDM engines only.

In the interest of supplying as many parts for the UZ aftermarket, we had to complete the set and offer this one as well!

We developed these, custom, in house, specifically for the Toyota V12 engine. They look way better than stock, and are a bit lighter as well! Replace your old, crusty pulleys with these instead.

These pulleys are the same size, direct replacement for stock, so no worries about anything being underdriven, or having to use a different belt size.

Another way of making life easy when having to replace the factory clutch master cylinder, either from being worn out, or having a stiffer clutch that necessitates a larger bore diameter master cylinder! This new product lets you bolt on most popular aftermarket master cylinders, and is just one more part we're offering to help keep these cars sustainable on the road!

The OEM Toyota Master Cylinder for the clutch has been discontinued! If you want to repair your car correctly (not using cheap parts of unknown origin), you'll want to opt for one of these kits! 

Looking to add some style and wake up that Crown a bit? XAT can make you a custom stainless exhaust! This would bolt directly to your factory 2 bolt cat and replace everything up to and including the muffler.

These are custom made to order, so we're able to make variations and changes to suit your tastes! Looking for a different style muffler? Single tip? Flat black? Let us know what you're looking for, and we can get you covered. 

Each exhaust is hand made on an actual JZS155 Crown, so fitment is sure to be right. Fits hardtops and sedans. Not compatible with JZS155 Majesta. Please note this exhaust is strictly for off road use only. Check your local laws before purchasing. Depending on what style muffler you are using, you may need to clearance your stock bumper cover. Open a dialog with us if youre looking to avoid this

After the surprise success of our 2GS/SC430 brake adapters, we've started development on an IS300 version as well! These brackets let you bolt on 4 piston LS460 calipers to your IS300 / Altezza, making an inexpensive but VERY effective brake update option! Thanks to Toyota parts interchangeability, that means they also fit Chaser, Cresta, Crown, Mark 2, Progres, and Verossa chassis'!

In our continuing support of Lexus performance products and the UZ platform, we have finished this set of brackets to mount 4 piston LS460 / LS600h brake calipers to any USDM IS300 2000-2005!

These brackets are ideal for those DIYers that are looking for an inexpensive option for brake upgrades. You keep your factory brake lines in this bolt-on solution; all you need is a set of front 2007-2018 LS460, LS460L, LS500, or LS600h fixed 4 piston brake calipers, LS460 fitment pads, and a set of 2008-2014 IS-F14" rotors!

Although the roll center adjusters aren't mandatory, they provide a bolt on solution. You do not have to run them, though if you do not, you may need to modify the mounting hardware. They will improve the suspension geometry on lowered cars at any rate, so we highly recommend them.

Please note that the LS460 does NOT use 5x114.3 rotors, so you will NOT be able to bolt on the LS460 rotor. We do not have fitment confirmation on the larger LS460 F-Sport 6 piston Brembo brakes, though they may also fit when used with larger rotors.

Additionally, you will most likely need 18" wheels to fit over these. The only 18s we have found to not fit so far are some Enkei RPF1s and IS250/IS350 F Sport front wheels. We cannot make any promises on what else will not fit, however every other 18" wheel we have tried does fit over these brakes, including factory X-Runner wheels, Enkei NT03+, G35 Ray's wheels, etc.

Please also note these will fit the S150 series hardtop Crown, not the Crown Majesta. The Majesta JZS155 will use our GS300 adapter brackets

Brackets fit:

☼ 2001-2005 Lexus IS300 / Toyota Altezza JCE10, GXE10, SXE10

☼ 1992-2001 Toyota Chaser / Cresta / Mark II GX100 (1G-FE), JZX100 (1JZ-GE, 1JZ-GTE), JZX101 (2JZ-GE), SX100 (4S-FE), GX90, SX90, JZX90, JZX91, LX90, LX100

And possibly others!

You will receive 1 pair of brackets to mount both front calipers, as well as mounting hardware. Please note that we normally stock the brackets and rotors, however it may take 1 week to ship the calipers. Please note that free shipping is for the continental US 48 states only

Pictures show the RWD K17 type caliper being used. The AWD N18 caliper has the same bolt pattern, but the caliper sits taller on the rotor. As such, the N18 version will not work with the IS-F rotor. You'll need to stick to the K17 type. We do not support the N18 caliper, so you will need to verify before installation. We also sell the K17 calipers brand new for a very affordable rate!

Keep in mind these are designed for off road use only and professional installation is required. We have been driving on these kits for over 3 years, but use at your own risk.

Fully delete your stock drum rear e-brake and run an independent hydraulic hand brake on your drift car! Excellent for those with Crowns, Mark IIs, Crestas, and Chasers with foot emergency brake setups that are looking to get sideways with a big upgrade!

The caliper used is the factory rear 2 piston LS460 caliper from the non-sport, RWD cars. They are marked A16 in the casting. Be sure you have the correct ones!

This kit works with both our rear Wilwood FSL rear upgrade kit. You will need to run our upgrade kit due to this using the larger Supra TT rear rotor. This will NOT fit a stock rear brake setup. You will also be replacing the factory drum e-brake entirely with this, so you will not be able to reuse that.

Not everyone is looking to go wild with their car! We offer this as a simple bolt on solution for those with the 10th generation hardtop Crown (JZS151, GS151, JZS155, etc.) or RWD Crown Majesta (JZS155, UZS151, UZS157) who will be fine with just OEM style brakes.

Please note that we have not found a 100% direct replacement for the hardtop stock rotors. With this kit, you may need spacers to fit. You should still be able to fit the factory JZS155 15" wheels, however we have not confirmed fitment yet.

Listing includes BRAND NEW direct fitment upgrade:

• Calipers
• Rotors
• Pads

The Majesta version is direct fitment and will fit your wheels, confirmed.

Is it...could it be?? The world's first JZS155 specific turbo kit?! OMG!

We're huge fans of the 10th generation Toyota Crown here at XAT, especially the hardtop version with pillarless windows..and yes, we have a few of these cars. This kit includes everything you need to turbo your 2JZ-GE VVTi in your RHD Crown--no steering rack, downpipe, manifold, or wastegate issues here!

Our kit has been developed entirely in house on one of our own JZS155 Crowns, specifically for 2JZ Crowns. Please note we cannot guarantee fitment on the Crown Majesta JZS155, as those are based off of the GS/Aristo JZS155 chassis, and might have slight differences in fitment. We have a customer making 558rwhp on this exact kit and bone stock internals!!

Some of the many benefits of the "zenki" 95 to mid-97 Crowns are that they still have the same rods as the turbo 2JZGTE, cable throttle, and no MAF! An ECUMasters DET3 and some injectors will easily get you to 500+ HP!!

The intercooler is rated for 700 HP, which is more than the turbo is capable of. So if you wanted to upgrade the turbo down the line, you still have room to do so. This kit is specifically built to make a mean street car with a very responsive turbo.

The intercooler will replace your factory crash bar behind the bumper cover. There's only some minor clearancing recommended just below the stock grill (which is not visible with the bumper cover installed). We also weld a 90* compressor outlet elbow (included with the kit) directly to the turbo to make installation a very straightforward, bolt on install! The factory bumper cover does NOT need to be cut/modified, and the intercooler fits nicely between the frame rails! We're big fans of this style for that sleeper look. You may also need to move/bend the lines going from the auto trans to the radiator, if you still have an auto trans.

The base kit does include a BOV, though we also offer better options. Whichever route you go with, we weld the BOV on the cold side piping for you that matches your blow off valve selection.

Fabricate your own exhaust for your ride! This kit is for popular vehicles with UZ engines, and there are plenty of ways to option it out for your preferred setup. All parts and piping are quality T304 stainless steel. U-J bends are mandrel bent, not crush bent, as to keep even and consistent flow.

Base kit includes:

• (4) 2.5" U-J bends 
• (2) 5 foot sticks of straight tubing 
• (2) stainless Vibrant mufflers
• (2) flex joint couplers

PLEASE NOTE THIS IS FOR OFF-ROAD, RACE ONLY APPLICATIONS ONLY. Modifying and tampering with factory emissions equipment is illegal in many jurisdictions, so please consult your local laws BEFORE ordering. 

This kit is NOT available to ship to California.

This is also NOT a 100% complete kit. You will need a competent welder to finish up the rest on your specific chassis. Different and additional parts are also available by request! Please contact us for a shipping quote if you're not located in the US 48 states.

Our mail-in head program for a performance refresh for your JZ cylinder head will save you $$ and outflow the factory head anywhere from 30-35 CFM on the intake ports and 20-25 CFM on the exhaust ports! Our engine building specialists include a full clean, 3 angle valve job, and pocket port for your JZ project.

Please note shipping is not included on this listing. That will have to be quoted based off of your location. We can supply a shipping label to get your head to us if need be as well.

See actual bench flow results of a completely stock 20+ year old head before and after porting in the second picture!

To port or not to port, to increase valve size or not to increase valve size, 3 angle or 5 angle valve job? These are the questions any person entering the world of a reworked head ask, especially 2JZGTE owners.

Communication is the key, so feel free to call or email us! Depending upon availability of parts and machine shop time, it may take weeks, so please plan your build accordingly. Scroll down for more info!

Please note that push-lok fittings may be sent out instead. If you need something different, please let us know.

When doing any boost install to the Lexus IS300 or GS300, one must take absolute consideration of the limits of the engine, fuel system, engine management and operating environment, before you find yourself with a blown-up engine.

There is much discussion on how much power the stock fuel system, engine management system, etc., the engine can handle. It is our "base" experience that on the factory small fuel injectors you can run about 285 RWHPsafely. Safely would be defined as injector duty cycle limit not exceeding 85% with an air fuel ratio under boost of 11.5 to 12.0 to 1 on good quality premium unleaded fuel. I know people have made 375rwhp on factory injectors, but this number is our opinion of "not safe", not everyone's.

Not every customer requires the complete Stage 1.5 Accessory Kit, and frankly, some just want to swap their IS300 from the returnless factory style fuel system to the "required" Return Fuel System, which is a must for any boosted application in the IS300. Without this, you cannot successfully install a proper fuel pressure regulator.

I said all that, to say this. We have this Fuel System Set-up Package which converts your factory fuel system to a return style fuel system. All parts are in this kit. Figure an afternoon to do the install for an experienced mechanic.

This kit contains the following:
Return Fuel Line Package:

FueLab 1:1 Rising Rate Fuel Pressure Regulator -6 AN

100 psi rated fuel line kit

All AN fittings

Fuel pressure gauge (mounts to FPR)

Other fuel pumps are available at extra cost for those needing more fuel flow!

If you are building a dual or triple feed fuel setup for your GS/IS, please contact us as we have a separate kit for you to fit your needs 

Although it's not ideal, we do have a custom made to order plug n play harness we can make for your 89-97 1UZ equipped car (SC400, LS400, etc.). The Link G4X AtomX ECU is made to run minimal inputs/outputs as a budget standalone option for 4 cylinder vehicles, however it is possible to use this same box to run batch fire injectors, and wasted spark ignition on a V8 like a 1UZ. Link even has a sample map in their PCLink software to speed up the process!

As an official Link ECU dealer, we can also supply the Atom itself, and any ancillary sensors you may need!

Please note the Atom is not currently capable of controlling the IAC valve, so you will have to run without one or find other ways to control idle. This is for manual transmission applications only. If you intend on keeping the auto transmission, you would need to run an external transmission controller, manual valve body, or find another way to control it.

Base listing does NOT include the ECU as well, the AtomX ECU is an optional extra.

Finally, a bolt-in clutch pedal bracket for LS400! Designed and produced in the Grindhouse skunk works, XAT Racing has just what you need to be doing clutch kicks in Grandpa's land yacht. This adapter uses a specific Wilwood clutch pedal with remote reservoir available from the dropdown menu! The end product is a 100% bolt-in assembly with many available cylinder bores and adjustable pedal engagement. Fitment has been confirmed on LHD UCF10 chassis (89-94 LS400) only. Contact us for UCF20 and rollcage-mounted options. Please keep in mind these are often made to order and may have a delay in producing them. You will need to have the clutch line custom made of course, depending on transmission used. Let us know what you need for your application and we can supply that as well!

The very same line we are using in our custom 2JZ-GE Crown JZS155 turbo kits! This will fit all JZ engines receiving boost for the first time and supplies the turbo of your choice with much needed oil.

-3 or -4 feed , sandwich adapter plate, simple and effective.

The optional drain line kit we supply is premade for a rear sump oil pan. If you have a front sump pan (JZS155 Crown, IS300/Altezza, Aristo/GS300), you will need to shorten the drain line and use the hose end we supply to have proper fitment with it. 

Please note due to draconian laws, we are not able to ship these to a California address. Please support the RPM act.

A simple, clean installation for your 1UZ swap! These blockoff plates are for the 89-97 1UZFE engines (LS400, SC400) and bolt on to the intake plenum. Get rid of all the stuff you're not using and clean up your build!

There's a few ways of deleting EGR from a non-VVTi setup. Our block off plate goes on the intake manifold itself. If you put it in between the intake manifold and the upper pipe, everything else can stay as it is. Otherwise you would ideally weld the header flange shut to stop any potential leaks there, and then you can remove the piping system entirely. 

For off road vehicles ONLY.

This XAT flywheel is perfect for those who want a simple and straightforward flywheel for a manual conversion on their Toyota/Lexus V8. Affordable cast flywheel with OEM quality and OEM ring gear. 

Excellent for starter projects and conversions, as well as daily street driving. This flywheel weighs 20 lbs 4 oz. Looking for a bit more performance and less rotating mass? 

Check out the 13 lb XAT Chromoly Flywheel instead!! Our flywheel utilizes the proven torque holding clutches of the SW20 MR2 TURBO 3S-GTE. We offer clutch setups to suit everything from a stock engine all the way up to 680 FT/LBS with this flywheel! 

For installation when using the optional ARP bolt kit, torque to 70 FT/LBS using red thread locker/loctite on the bolts, and tightening in a star pattern, not one next to the other. We also recommend tightening down in 2 or 3 passes as well, instead of going from finger tight straight to 70 ft lbs. This flywheel does NOT require any spacers to bolt on, not even the factory spacer that goes from the crankshaft to the factory flex plate.

This flywheel is meant for our W55/W58, R150/R151, R154, KA, and SR transmission adapters. This will NOT work with our CD009 / JK series Nissan 6 speed adapter! Also not meant to fit international H151 models

Higher horsepower means more oil demand. When you're running twice or three times the stock power output, you absolutely have to be sure your engine is getting lubricated everywhere it needs to! Especially if you have an aftermarket oil cooler to keep oil temps down! What does XAT do to bring you options for a better oil pump? We take a brand new OEM one, remove all hard edges, radius all corners, enlarge the front main seal drain, and shim the pressure relief valve to give more max PSI. Make sure you get a quality oil pump for your engine, from the professionals at XAT!

Please note that we start with an OEM part, even though it will not say Toyota on the box. We do not use knockoff brands for this, and will not risk an engine on poor quality or questionable parts.

We are only currently able to source 1URFE and 3UR covers also at these prices. If you have a 1URFSE from a sedan (GS460, LS460) you will need to send your front cover and oil pump in.

As a great supplement to our turbo kits, we commissioned these hand made in the USA patch adapter wiring harnesses to plug in to the ECU Masters DET3 (Digital Engine Tuner 3) piggyback system, as well as the factory JDM 95-97 JZS155 hardtop Crown ECU and harness.

We're huge fans of the Crown at XAT, having brought over around a dozen by now. This terrific platform yearns for a turbo setup! Since a standalone ECU is not ideal for everyone or every build, we now offer this alternative that keeps all factory functions and drivability of your 2JZ VVTi Crown, but lets you fine tune further and swap out injectors for when youre ready for more power!

We strongly recommend going this route in conjunction with our turbo kit. You will be limited to wastegate pressure and low boost on the kit, unless you upgrade injectors/fuel system and go with a tunable ECU.

*not actually guaranteed to get you any bitches. That's on you, homie.

When we took a look at the previous generation of adapter plates, all we could see was room for improvement and higher quality. We wanted a plate that would mount PERFECTLY with zero slop. It needed to look good and perform even better. DON'T get stuck with an overvalued, sloppy plate that ends up costing you input shafts and has poor fitment. You can go with a less expensive alternative and end up with broken parts, or you can do it right the first time with us! No complaints with over 5 years of service.

This billet aluminum adapter plate reuses your factory 4 speed auto 1GZ bellhousing (1997-2004). It will require you to cut off the CD009 bellhousing, which gives MUCH more room to work with in most chassis. Alignment of the input shaft becomes dependent on this plate and not the quality of the bell housing cut, so worry not! This isn't like other kits out there. 

2005-2017 bellhousings will not fit with this adapter. Although the GR-to-CD009 adapter plate we offer would bolt up, the thickness spacing is still wrong

Regardless of which clutch you use, you will need to use the Quarter Master throw out bearing. 

With single disc clutch setups, this kit is designed to use our custom flywheel that uses off the shelf "Z32 turbo" (89-96 Nissan 300ZX twin turbo) clutches, which are inexpensive, readily available, and hold power well. 

Please see the listing below for the flywheel needed. Please note that with a single disc clutch, this requires a proprietary flywheel. OUR "OEM STYLE" AND "LIGHTWEIGHT" XAT FLYWHEELS WILL NOT WORK WITH THIS TRANSMISSION. You will need the specific CD009 flywheel made for this application.

The twin disc setups include their own flywheel, but will also need a ring gear for the starter (the OEM auto flex plate). 

Included with purchase on this listing:

• Adapter plate with hardware to install
• Quill tube for mounting the hydraulic throw out bearing
• Pilot bushing adapter, with bushing installed
• Throw out bearing (optionally)

XAT Racing took a hard look at the concept, and decided to go all in with the "Toyota Big-Block" design. These V12s have started becoming more popular over the past few years! This will fit all versions of this transmission: CD001, CD003, CD005, CD008, CD009, JK41A, JK41B, JK40C, 1EA0A, and 1EA0B from the 2003-2008 Nissan 350Z/Fairlady Z, 2009-2020 370Z, Skyline V35 and V36 non-GTR sedan and coupe, and Infiniti G35 and G37 

Our products are CAD designed with OEM blocks and transmissions on professional equipment by industry professionals. No bad measurements, no flame cuts, no warped discs, no nonsense. You should be using a 3/4" master cylinder in tandem with the TOB we use.

This is the missing link for doing the 1GZFE swap, or simply adding a manual transmission to your already badass Toyota Century. Our CNC process for manufacturing the plate results in an extremely precise adapter plate, laser tight tolerances, and a focus on quality that has yielded a product that will produce less wear on the transmission and clutch. The adapter kits come with the needed pilot adapter and bushing as well. This is the tried and true kit from XAT Racing, except no imitations when it comes to Toyota V12 1GZs. Sorry, V12 not included.

You can also use the less expensive RAM throw out bearing with this kit, however we do not support it. You will need to drill and tap the plate at your own risk to mount one.

WE HAVE COMPLETION!! First batch of cams have been completed. These are not simply overpriced regrinds of stock cams. There are machined from new billet cores.

These cams will be for anyone looking to get the most out of their Lexus GS460, LS460, Toyota Crown Majesta etc. with the 1URFSE engine or LS600h with the 2UR-FSE (not the GSE in the F cars--RC-F, GS-F, LC500, etc). THESE ARE NOT MEANT FOR THE 1UR-FE TRUCK ENGINE IN THE TUNDRA, GX460, ETC.

If you've already done basic mods like intake, exhaust, and tune, this is the logical next step for you to have some noticeable gains, however you can expect to need at least an upgraded valvetrain to run these.

For the manufacturing process, we start with proprietary cast iron billets, CNC machine the lobes, and finish off with double heat treatment, 5160 induction hardening, and Tufftriding.

Pictured is one set from the actual run of UR cams made!! We have just a few sets left in stock, as these are low production numbers. Once they leave, there may be a few weeks wait time before we get more in

Cam specs for XAT cams:
294 duration, 7.17 cam lift intake, 245 duration at .050"
300 duration, 7.17 cam lift exhaust, 247 duration at .050"

With the factory rocker ratio, that's 10.76mm of valve lift with our cams! As such, you should verify clearance with your pistons and these cams. In most cases, you may need custom pistons.

UZ series V8 Stainless Header Flanges, fits 1UZ, 2UZ, 3UZ, VVTi or non-VVTi. MADE IN THE USA!

Pre89 1UZ and 3UZ fitment confirmed reusing the stock Supra brake booster! Billet mounts for your aluminum UZ engine (or motor mounts, if you're wrong) into the MkIII Supra chassis! The pre89 version is finished and now available. If you have a 1989 model year Supra, please verify the subframe you have (or if your engine mounts were square or round) before ordering.

Helpful hint: Square mounts came on the earlier cars, round on the later. 1989 was the crossover year, so please verify on your car.

Includes rubber isolator mount! Well, not actually rubber, it's UHMW (ultra high molecular weight) with a shore hardness of 68D, roughly equivalent to over 100A (which is a more familiar comparison scale). Despite being one of the smoothest V8s ever created, we prefer having a dampening barrier vs. a "solid" mount to reduce NVH for street cars.

These make bolting in your favorite UZ engine a breeze. Billet aluminum mounts, milled on a 5 axis CNC machine IN THE USA. Only the very best out there!

These are for the non-VVTi 1UZs, VVTi 1UZs, and all 3UZ engines. Please note the 89+ version is different, but we do stock both!

We cannot confirm fitment with the 2UZ. The iron block engines tend to have a different mount location

You've asked for it, so here it is! At long last, a viable rear brake upgrade solution to go with our front LS460 brake option!!

Fitment confirmed on all 2GS cars, including:

• 1998-2005 GS300
• 1998-2000 GS400
• 2001-2005 GS430
• 1997-2006 Aristo
• 2001-2010 SC430
• 1998-2005 European and JDM IS200/IS300 (not USDM)

With these adapter brackets, you will also need:

• 2001-2006 Lexus LS430 rear calipers
• 2001-2006 Lexus LS430 rear brake pads and hardware kit
• 1993-1998 Toyota Supra twin turbo rear rotors

And that's it! You can reuse factory brake lines, though we strongly recommend going with stainless braided lines for your application. Our brackets include mounting hardware, though you will also need the radial mount bolts for the caliper, which we have made an option as well. The factory Toyota/Lexus bolts aren't cheap, but they're perfectly suited for the task. They're thick, use rolled threads (instead of cut threads), and even come with thread locker pre-applied. Even if you plan on sourcing the rest of the kit yourself, we strongly recommend getting the caliper mount bolts from us at the same time at least

Please note you may need to shorten the caliper mount bolts ~1/16" for fitment. This otherwise is a bolt on kit.

Fits all 2GS cars (1998-2005 GS300, GS400, GS430), SC430, and 1998-2005 European and JDM IS200/IS300. May also fit others though this is unconfirmed. Most likely will not fit LS chassis. Does not fit 1GS cars (1992-1997 Aristo, GS300) or USDM IS300 2001-2005 without modifications to the bracket. We cannot accept returns on modified parts. Please contact us with your VIN to verify fitment.

We've focused on the 1UZ, 2UZ, and 3UZ engines for many years now, and will continue to develop more and more parts for those iconic V8s. We're also now starting to gear up for the UR market, starting with performance camshafts and a billet dry sump oil pan! We're building this around a 3URFE engine, and suspect it will likely fit the 1UR 4.6 and 2UR 5.0 V8s also. Confirmation will come at a later date.

The pan is being designed to be used in conjunction with the Moroso dry sump oil pump. This kit is being modeled after the TRD UZ V8s one, but being built specifically for the larger UR block.

Please note, this is not a complete bolt on kit. We are developing these still, which will be unique to each chassis. Expect to sacrifice your A/C compressor for this, or possibly have to relocate other engine driven accessories. You will still need the belt driven oil pump, lines, tank, and any other ancillary parts (such as cooler, filter housing, etc.), though these parts will depend on intended use, goals, and budget for the vehicle.

This is a complete kit, with twin disc clutch assembly, install kit (ARP flywheel bolts, clutch hardware), button flywheel, and spacer as needed. 

Which engine? Which transmission? All of them! 

We have a version for your UZ engine, with Z33 / Z34 trans, R154, V160, or W58! The twin disc is recommended for 800rwhp cars for street/drift/endurance. The sintered metallic compound is one of the highest quality materials for clutches. This clutch has slots between the segments to help cool the clutch easier, and extra thick padding to last through an extreme amount of abuse! 

All feedback for this clutch from our many customers over the years has been overwhelmingly positive. Clutch pedal isnt overly aggressive, it can still slip for street driving, yet has no problem holding gobs of power. Here at XAT, we often measure power in gobs. This kit holds "many" gobs. This is the 8.5 inch version we recommend most for street driven cars.

The starter gear includes the ring gear needed to start the car. The much smaller button flywheel has much less rotating mass to deal with and works very well, but has no starter motor engagement. The base kit includes the button flywheel, with an option to have a full size flywheel and clutch combo. The assembled RaceLite clutch and flywheel weighs 22 lbs 14 oz.

If this is your first time with an XAT clutch conversion, you will need the starter gear as well. Otherwise you can opt for the RaceLite flywheel instead and not need the starter gear or the button flywheel. You should be using a 3/4" master cylinder in tandem with the TOB we use.

How race car are you? Probably race car enough to have loose, bad mounts, floppy engine, or maybe none at all and you need the right ones to mount your UZ. These billet, made in the USA 6061-T6 aluminum engine brackets (or motor mounts if you're wrong) were designed to tighten up your 1UZ or 3UZ from flopping around and keep it properly corralled. 

The 2 piece design keeps it simple and bolt-on for any 2GS/Aristo 1998-2005 GS400, GS430, 2001-2010 Soarer/SC430, or even a UZ swapped 2001-2005 IS300. All hardware is included, so these bad boys are ready to drop right in.

Knowing Toyota, there are likely many other applications these will fit for as well. As we get confirmation, we will add compatibility notes to this listing. 

The version 3 we now have of these mounts is more modular and should fit any factory JZ or aluminum UZ application! Dont forget to select your chassis from the dropdown menu.

This billet aluminum adapter plate reuses your automatic 1UZ, 2UZ or 3UZ bellhousing. (U1 or U2 from the 4 speed and 5 speed autos. 3UZ 6 speed bellhousing will not fit). It will require you to cut off the CD009 bellhousing, which gives MUCH more room to work with in most chassis. Alignment of the input shaft becomes dependent on this plate and not the quality of the bell housing cut, so worry not! This isn't like other kits out there. This will also fit 2UZs, though the kit was designed to use the U1 bellhousing specifically.

Regardless of which clutch you use, you will need to use the Quarter Master throw out bearing.

XAT Racing took a hard look at the concept, and decided to go all in with the "Toyota Small-Block" design. These V8s have started becoming overwhelmingly popular over the past few years! This will fit all versions of this transmission: CD001, CD003, CD005, CD008, CD009, JK41A, JK41B, JK40C, 1EA0A, and 1EA0B from the 2003-2008 Nissan 350Z/Fairlady Z, 2009-2020 370Z, Skyline V35 and V36 non-GTR sedan and coupe, and Infiniti G35 and G37

This is the missing link for doing the 1UZFE, 2UZFE, or 3UZFE swap, or simply adding a manual transmission to your already existing UZ powered vehicle (LS400, SC400, and GS400 included). Our CNC process for manufacturing the plate results in an extremely precise adapter plate, laser tight tolerances, and a focus on quality that has yielded a product that will produce less wear on the transmission and clutch. The kits being sold by our "competition" are routinely a few thousands off and have sloppy fitting dowel pin holes. We have even seen competitor's products first hand being warped right out of the box! The adapter kits come with the needed pilot adapter and bushing as well. This is the tried and true kit from XAT Racing, except no imitations when it comes to 1UZs..

You can also use the less expensive RAM throw out bearing with this kit, however we do not support it. You will need to drill and tap the plate at your own risk to mount one.

You may also need other manual conversion parts, depending on your chassis. Please keep in mind you may need to use a 3/4" bore master cylinder with this kit. The factory master cylinder may be enough, however it will ultimately depend on your application. The majority of Toyota car manuals have a 5/8" bore master. The optional master cylinder we provide may require further chassis modification to bolt up to your firewall.

The GKTech shifter is great for relocating the shifter fit Lexus SC fitment and MkIV Supra fitment. Should also fit other applications as well, though that will depend on the chassis you're using and where the engine is mounted
