Cool off, thiccboi! This radiator comes in hard at 2.5 inches thick, 29 inches wide, 20 inches tall.

Will require modifications to lower mounting points and new upper radiator mount brackets. Please understand there is no direct replacement upgrade option on the market that will be a drop-in fix. We have confirmed this radiator to fit in the UCF20 chassis dimensionally, and further custom work will be needed to go from there. Factory UCF20 fan does NOT bolt up without modifying mounting provisions. You can expect to need to make radiator hose solutions as well. 

Pending fitment check on UCF10, early LS400. We will update this listing with results

For decades, we have exclusively installed NGK spark plug wires on all of our vehicles. NGK is an OEM, trusted brand, and there's no reason not to get the best!

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!

PPE Engineering is one of the longest running header suppliers for the Toyota/Lexus UZ V8 platform, and it's easy to see why! These headers are hand welded on a jig and nicely ported afterwards. These exhaust manifolds are made of 100% 304 stainless steel using a 4-1 design, and feature 1 5/8" runners with smooth formed collector and 2.5" outlet. They are a direct fit to the stock catalytic converters. Power gains are 18-20 whp and 20+ ft lbs!

Please make sure you select the correct car application so we can send the correct header design out for you. Price is for both headers. Please keep in mind these are often made to order, so there may be a wait time of at least 3 weeks or more.

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

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.

Please contact us for availability on the different rotor/caliper styles, as they go in and out of stock regularly!

We at XAT have developed an intermediary brake kit that slots just below the LS460 big brake kit that we sell! As we've discovered, the LS460 brake kit combo requires a minimum of 18" wheel, and some 18"s also will not fit. It's easy to recognize the fast growing popularity of JDM vehicles we grew up loving now being imported, as we have a hand in doing that as well!

This kit is specifically designed to use MkIV Supra TT rotors, meaning you only need 17" wheels to clear these brakes, giving an extra option for those looking to keep with period correct wheels and wheel sizes. Although we dont have a complete list of every wheel this kit will fit, if you suspect the LS460 kit may be too big for you, this is a terrific alternative, using OEM quality and Wilwood brand parts!

The steering arm and caliper may need to be modified on your setup to fit this brake kit, depending on application, if youre not using an angle kit. This had to be done on our zenki '89-92 UCF10 Celsior to fit, as well as our '96 Crown JZS155. Expect similar requirements on X90s and early X100s, likely on GS/Aristo as well. We have provided pictures of where we had to modify the caliper to fit.

Brackets fit:

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

When looking for a Limited Slip Differential  XAT Racing always goes with Active Tracking Service - better known as ATS or even carbonetics.  These LSD kits are available in 1.5 way or 2 way operation. Silent when taking tight corners so none of the metal on metal CLUNK CLUNK of many of the other brands of LSD kits.  

These kits ship directly from Japan -  So please expect a shipping rate of about 165 dollars on average to the lower 48 states. We can ship worldwide as well on these.

By utilizing the CC composite discs, the ATS carbon LSD posses the superior transitional characteristics from free to differential lock, enabling control that feels quite natural.

Principal characteristics of the Carbon LSD

* Gentle transitional characteristics that yield ease of handling from free to lock
* Small degree of slipping which provide a greater flexibility
* Super durable
* Stable differential lock performance which is unaffected by oil temperature changes
* Quiet operation without chattering noise
* Very high adaptability to many LSD oils from different manufacturers

Important - it is very important to monitor the differential oil temperature to keep it under 150 C degree (302 F). Continued driving with the differential temperature above that point might cause the carbon chips peeled off.

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.

Our Genuine ARP Main Studs Kit includes all 20 Head Studs, 20 nuts, 20 washers and 2 packs of ARP assembly lube to assemble one complete engine. Each main stud needs to be torqued to 60 ft/lbs 

If you are building a bullet proof UZ series V8, you will need the ARP Stud kits found here. 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!

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

XAT Racing Custom Oversized non-VVTi Lexus 1UZ LS400 SC400 Engine Valves. Please note these are made to order and often have a lengthy wait time of 2-5 weeks

XAT Racing exclusive! 1989-1997 1UZFE owners are no longer left out when it comes to upgraded valves! We now supply a full set of 32 oversized valves (16 intake, 16 exhaust) for non VVTi 1UZ engines. 

Factory intake valves are 33.5mm, exhaust 28mm, but we can make to your desired sizes. We typically do +.5mm or +1mm oversized valves. Pictures shown are of an actual set made for an early non-VVTi 1UZ customer that is looking to push some big HP numbers!

• +.5mm oversized valves bring you to 34mm/28.5mm
• +1mm oversized valves bring you to 34.5mm/29mm

Please note these are custom ordered parts. We do not typically stock a set of them, so expect 3-5 weeks wait time roughly for availability. These have 6mm valve stems and are not for the VVTi engines. We have other options for anything 1998 and newer.

Lexus LS400 SC400 GS400 1UZFE 1UZ non-VVTi Performance Camshafts by KELFORD. Looking for 1UZ cams? Here you are!

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!

NEW ESP H-Beam Forged Rods 1UZ 1UZFE

Top idler pulley for your UZ's serpentine belt drive! These billet pulleys include a serviceable bearing, so the pulley should last the life of the engine.

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.

NOW IN STOCK, READY TO SHIP!

The initial test batch has been finalized, mounted, and confirmed for fitment! The display pieces are natural silver, but the finished product will be anodized black or anodized clear (silver). 

Assorted UZ engines use different pulleys depending on generation and chassis, but any pulleys that arent a direct replacement for your setup are easily fixed.

Full set of pulleys weigh just 2 lbs and 6 oz! Depending on your application, that's a savings of 1 lb 6 oz over stock!

Included pulleys, one of each:

• Power steering: this should fit all UZ engines, however some UZ V8s do not have serviceable power steering pump pulleys. They are pressed on instead of retained with a nut on the front. If you intend on using the XAT pulley, you will have to swap out your power steering pump for one with the retaining nut on the front. Please note that the diameter of your original pulley may be different from the XAT pulley supplied, which is factory 3UZ size, and may be preferable for your application to have it overdriven or underdriven slightly at any rate.
• Tensioner idler: fits UZ VVTi engines. Slightly different from 1UZ non-VVTi engines, so you may need a 3UZ serpentine tensioner pulley bracket. The VVTi serpentine tensioner fits the non-VVTi engine without issue, however the non-VVTi timing cover that goes over it will need slight trimming if you go this route
• Alternator: This will fit all 1UZ non VVTi, 1UZ VVTi, 2UZ, and 3UZ engines
• Hydrofan bracket idler: Likely different from other UZ engines such as 1UZ VVTi
• Upper idler: fits all 98+ UZs, including 1UZ VVTi, 2UZ, and 3UZ engines

Some pulleys might fit your engine just fine but end up being a slightly different size/diameter. This may also change which sized belt you will need, so please keep that in mind when installing.

For example, the Celsior non-VVTi engines (both UCF10 and UCF20) DO use a smaller diameter power steering pulley than the USDM American LS400. This would spin the pully faster and "overdrive" it. For drift, race and motorsport applications, we recommend the larger diameter pulley to underdrive it slightly.

The Celsior non-VVTi power steering pulley is the same as the American spec SC400 one.

Here at XAT, we exclusively use Wilwood master cylinders for all our conversion kits. Tilton and Quarter Master are also both top tier options

If you are using an XAT clutch adapter kit or transmission adapter kit, you will need the 3/4" size 

This is what is needed for converting the Crown (JZS155, JZS151, etc.), Chaser/Mark II/Cresta (X90, X100, etc.), using our LHD UCF10 LS400 clutch pedal bracket, etc. where firewall height is an issue.

Wilwood’s Compact Remote Combination Master Cylinder, commonly called “shorty” master cylinder; only 3.375” long, is about the size of a roll of quarters. It’s available in bore sizes from 5/8" to 1.125”, and with or without reservoirs.

ACL Lexus V8 1UZFE/2UZFE/3UZFE Standard Size High Performance Rod Bearing Set

Need just the rod bearings? We typically stock these, the main bearings, and thrust washers!

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

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.

Clevite Mahle TM-1 1UZ 2UZ 3UZ Rod Bearings. The mains were discontinued, but these are supposedly still available at least. This listing is for 1 full set for your engine. Yep, all 8 rods, 16 individual bearings.

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!

Here at XAT, we exclusively use Wilwood master cylinders for all our conversion kits.

If you are using an XAT clutch adapter kit or transmission adapter kit, you will need the 3/4" size. 

This is what is needed for converting the A70 Mk3 Supra, A80 MkIV Supra, SC300, SC400, etc., among other cars.

This WILL NOT work with Crown (JZS155, JZS151, etc.), Chaser/Mark II/Cresta (X90, X100, etc.), using our LHD UCF10 LS400 clutch pedal bracket, etc. where firewall height is an issue.

Wilwood’s Compact Remote Combination Master Cylinder, commonly called “shorty” master cylinder; only 3.375” long, is about the size of a roll of quarters. It’s available in bore sizes from 5/8" to 1.125”, and with or without reservoirs.

ACL main bearings 1UZ. These are the bearings we use in pretty much every UZ build we do! They tend to be more readily available than some others. They will also fit any UZ engine, 1UZ-FE, 2UZ-FE, or 3UZ-FE.

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. 

Please note these typically take 2-4 weeks MINIMUM to ship out

ATEMU simulates most critical features of particular Toyota / Lexus auto transmissions which were available for UZ / JZ equipped vehicles since 1998. This makes it possible to obtain rated power from engine when using factory ECU and any transmission other than that ECU is designed to work with. Factory ECU would otherwise enter limp home mode with significant power and torque loss (for example, VVTi set to max retard for 1998-2000 Lexus LS400) Some non-critical error codes remain intact for simplicity of installation and reducing the cost for off-road application. These codes can be easily addressed with additional components if emission test has to be passed for street legal application.

We now offer the additional resistor pack to wire in if you need to eliminate the check engine light (CEL)

Fits both 6-speed (220mm) and automatic (200mm) differentials.

Powerhouse Racing Solid Front Differential Mounts (Ear Mounts) will firm up your rear end to be able to handle massive horsepower while reducing ET's and 60 FT times.

Don't waste energy shaking that differential around! Transfer that power through the differential, keep the rear end in place, and help eliminate wheel hop! A shaking rear end is a breaking rear end.

Precision CNC machined from billet 6061 Aluminum for perfect fit every time.

Please note: sold by the pair and only available in a Anodized Black finish.

MAY ALSO FIT Z30 SC300, SC400, SOARER, ARISTO, GS300, GS400, GS430, LS400, LS430, AND CENTURY. FITMENT NOT CONFIRMED, TEST FIT AT YOUR OWN RISK. We will not be able to accept returns on parts that are already test fit. 

Please note these work best in the non-VVTi 1UZ engine. The 1UZ VVTi, all 2UZ, and all 3UZ engines should look at the SuperTech kit instead

This is the perfect solution for those looking to add more seat pressure for higher revs and larger cams in the UZ engine (non-VVTi and VVTI versions included).

This single wound spring will work perfect with the factory retainer and keepers. Coil bind is an immense 550 thousandths. We also have an option to include titanium retainers for a non-VVTi 1UZ. Please note that we currently only have BC retainers for the non-VVTi 1UZ engines. The springs will fit the VVTi and 2UZ engines, however you will either need to reuse the factory retainers, or use the (recommended) full SuperTech kit instead. Please see below for that listing.

What does this mean? You can run more cam than the unmodified head will take! This spring is good to over 10,000 RPM with proper supporting mods. Seat pressure on standard 1UZ is 72 lbs, and in VVTi engines is 67 lb. Price is per set of 32 springs, for 1 complete engine.

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.

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.

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. 

Sticking with the stock rods for your rebuild? Make sure you grab these upgraded ARP rod bolts to keep them together! These are a great option for budget builds, especially if you will use a set of pre94 rods. For higher HP builds (especially if your engine sees boost), we recommend upgraded rods, which include the rod bolts with them. These ARP rod bolts however are more than adequate for a fresh stock rebuild. Don't forget to have your rods inspected and reconditioned if you're reusing old rods!

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.

Don't get stuck using those old, used, obsolete hand-me-down Supra injectors, start fresh with a healthy size and don't look back! These drop in to your stock fuel rails!

All Victory injectors start out as Bosch cores. They are then sized and matched within 1-2% providing exceptional idle quality. All injectors come with a limited 2 year warranty (minus 2200cc injectors.) You will also receive 1 free cleaning within the first 2 years! All injectors are a top feed high impedance injector and a direct drop in on the 1uz/2uz/3uz. VVTi engines supported as well. Make sure you select your size from the drop down menu! Includes a full set of 8 for your UZ engine

Please contact us for wiring options. While we try to sell these as drop in, plug in injectors, the plug-n-play adapters may be on backorder. You may have to wire in the 2 wire connectors to your harness yourself. 

In most cases, we recommend 1.3mm head gaskets on 1UZ/3UZ (1.0mm on 2UZ), and if you are running custom compression aftermarket forged pistons. If you are keeping the stock pistons and looking to lower the compression ratio for more boost, we recommend a thicker head gasket such as 2mm. This is for BOTH head gaskets.

The 1UZ version of the head gaskets is specifically for the non-VVTi engine and does not surround the oil port going to the VVTi solenoids

Please keep in mind some sizes are exclusively made to order nowadays and will have a 1-2+ month wait time. The OEM head gaskets are more readily available.

Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each engine, Cometic offers a number of options to suit your specific build and needs.

The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound, and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.

The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.

C4136 and C4137 offer a standard bore size of 92.5mm. C4211 and C4212 offer a standard bore size of 98mm

Please call or email us for an ETA and cost on other bore sizes, and note that they are special order and will take about 2 weeks to ship.

For those that need more electricity than our 150 amp option can provide, we have teamed up with JS Alternators to offer these custom made to order options! Even better, theyre plug and play, no adapter wiring needed!

JS Alternators also requires their universal Big 3 wiring kit, or otherwise similar wiring upgrades in addition to the factory wiring in order to handle the higher output. The big 3 Wiring upgrade is an ADDITION to your factory wiring.
All factory connections need to remain connected. For protection, it is recommended to add an in line fuse to the positive wire. All grounds must be cleaned to bare metal and properly secured.

Big 3 wires are 1/0 gauge pure copper cables. 1 positive to connect from the positive stud on the alternator to the positive battery terminal. Other 2 ground wires go from the alternator mount bolt to frame/chassis, and negative on the battery to frame/chassis.

Most JS Alternators are custom built to order and typically take 5-15 business days to be built and shipped. All JS alternators have a lifetime warranty on labor, and 1 year warranty on parts.

Hairpin units are commonly called 6 phase. They produce more output at idle and are more efficient than a conventional alternator. JS Alternators hairpin units feature premium bearings to withstand high engine rpm and utilize dual plate rectifier with 12 heavy duty diodes for improved cooling. Hairpin Units are a more reliable alternator to withstand high heat, high demand for car audio, marine, and racing applications.

Doing a 2JZGTE swap, but found out you have the wrong oil pan? This might be your fix! 

Rear sump oil pan is needed for fitment in the following chassis: 

• Mk3 Supra A70
• MkIV Supra A80
• SC300/SC400
• Soarer
• Toyota Pickup
• many BMW applications.

Front sump oil pan is typically needed for fitment in the following chassis: 

• Nissan 240SX (S13 or S14)
• BRZ/FR-S/GT86/Toyota 86 "Toybaru"
• Lexus GS300/GS400
• Lexus IS300
• Lexus LS400 UCF10 or UCF20
• Crown. Chaser. Mark II, Cresta

Neither of the above lists are complete, just some of the confirmed fitment needed

This will also fit 2JZ-GE engines! The bottom line is, it takes 64 parts to do the swap and that includes a tube of Toyota gasket FIPG sealer.

Everything is included from nuts and bolts to the pan, all stock GTE oil pan parts.

If you live outside the USA, which many of our customers do, please contact us directly with your details so we can get an accurate shipping quote to your location.

Note: Picture is for reference purpose only and shows the large pieces (NOT ALL), but this gives you the idea, all Toyota and how big the box container must be.


Please note the front sump dip stick tube is discontinued and no longer available. The dipstick itself is the same for front or rear sump engines 

UCF20 Celsiors have their own hydrofan pulley, so we set out to make those as well! This pulley is actually specific to all 1995-2000 Toyota Celsior UCF20 and UCF21 engines (both the 95-97 non-VVTi and the 98-00 VVTi), which have a different bolt pattern on their drive pulley hub from other hydrofan setups. 

If you have an imported Celsior, or are swapping an engine from one, you'll need this specific pulley to finish out the kit, if you plan on keeping the hydrofan setup working (which we definitely recommend if you have the choice)

This service includes modifying both heads, not just one side. You get a full port job, 5 angle valve job, cylinder head inspection, and the heads get hot tanked for a proper cleaning. We offer this service for all UZ engines, VVTi or non. Regardless of what chassis your engine is out of, we service them all! LS400, LS430, GS400, GS430, SC400, SC430, Land Cruiser, Tundra, Sequoia, GX470, LX470, etc.

Please keep in mind that your heads will likely require extra work: heads will typically need to be decked, valve lash needs to be set (we can do this, will need your cams), and you may need other parts replaced such as valve guides. We will keep in touch with you during this process and let you know what your setup needs.

For the 1UZ non-VVTi engines from 89-97:
We offer a spring and titanium retainer kit using Brian Crower parts. We also can get custom valves that are +1mm oversized and use a shimless bucket to adjust the valves after installation.

For the 1UZ VVTi, all 2UZ, and all 3UZ engines from 1998-2013:
We offer a spring and titanium retainer kit using SuperTech parts.

XAT Racing/ MANLEY Stainless Steel swirl polished valves are offered in stock or 1mm oversize sizes for our build process, as well as brand new Ferrea valve lock keepers

You cannot define every possibility in a single description or for all applications, but 'generally' speaking, what we provide with our Street Cylinder Head Refresh package is great for up to 8,000RPM, more RPM would be possible with proper optional valve train.

In reality, no matter what purpose/intended use of your build, you will benefit! The truth is unless you are building a 1300HP+ drag car, you can pretty much eliminate any serious deep cylinder head porting. You simply do not gain enough volumetric efficiency by hogging out a ton of metal in the heads, unless you are running a silly-high lift custom cam.

If you live outside of the USA, NO PROBLEM! Please contact us for a shipping quote and we will be happy to help you out! PRICE DOES NOT INCLUDE SHIPPING TO OR FROM US

1UZ ACL RACE Bearing Kit 1UZFE 2UZ 3UZ INCLUDES RODS AND MAINS

ACL bearings are designed for the engine that requires a tougher bearing for high RPM and power. The multi-layer design is derived from years of race testing and R&D. Race versions are coated with ultra slick oil retaining film for added protection in your competition engine. ACL bearings are available in standard or plus sizes for more oil clearance for high temp due to forced induction or higher revs.

As of recently, only the OEM thrust washers are currently available. We expect Clevite/Mahle and ACL thrust washers to be available again in mid 2024

Link continues to gain traction in the UZ Toyota/Lexus V8 market, and rightfully so! They have an excellent selection of options available, and are an XAT favorite when it comes to engine management. Why pay extra for the AEM name when Link is just as (or even more) capable?? From now, on, you can expect all XAT projects to be powered by Link ECUs.

Each harness is custom made to order, so please be patient as you can expect a 1-2 week wait time for manufacturing typically. Please feel free to reach out to us beforehand and let us know what kind of application this is for. Swapping a 1UZ into an S13 or S14 240SX? Putting a 2UZ in a Tacoma/pickup? Factory Crown Majesta or GS430 getting "the beans?" Let us know so we can be sure to have the right harness made for your project.

This is not for a full engine harness, does not include ECU or sensors. This listing is for a plug-n-play adapter to fit your factory harness, whether it remains untouched or is rewired for a swap. Depending on your plans, you may need other parts as well for everything to work properly. If you're boosting it, you'll no doubt want MAP and IAT sensors to go along with it. Although superior up and down, the VVTi engines also have additional considerations over the non-VVTi, and reaching out to us via phone or email (sales@xatracing.com) is the best way for us to get you situated with what you need.

Please reach out to us with any and all questions, as your application may need more consideration or wiring than standard

These are custom made to order. Expect to send in your original harness, and minimum of 10 week wait time.

Finally, a full harness for your V8 swap to make things much easier! We've done more than a few over the past decade, and now we're teaming up with the renown Dr. Tweak to offer a top shelf harness and their lifetime warranty! 

These harnesses are all custom made for each individual application, so in many cases, we will need a core harness to start with. Expect to need to send in your UZ harness, as well as your intended chassis' factory engine harness, depending on which it is. Connectors typically do not get reused from the original harness'; we just need them to verify connector type and length as the UZ engines have a variety of harness differences depending on year and chassis.

Please contact us and let us know directly what your application will need regardless, and we'll be happy to get another UZ powered vehicle out there tearing it up!! As of right now, we only have support for automatic transmissions if you run the factory ECU for them. 

Standalone applications will require a dual ECU setup in most newer 1998+ chassis'. On Toyotas specifically, the factory chassis ECU gets retained for MultiPlex compatibility, meaning the factory ECU will control the A/C, gauge cluster, throttle, auto transmission, ABS, etc. Feel free to reach out to us with what your swap is and we can make sure you get the right price and harness for your application!

What better option than factory? Instead of paying $400+ for an alternator in a Toyota box, we offer this same OEM alternator for a much more reasonable price. This specific listing is for the 90s style 3 pin oval connector. Please verify that you have this same oval style, and not the round 4 pin of most of the 2003+ UZ engines.

Once again XAT Racing is filling the gaps in the TOYOTA V8 market with another custom product made exclusively for the TOYOTA UZ series V8 engines! When building a high horsepower engine, a good focus is on the durability factor of the parts used to complete the engine. The engine's intake and exhaust valves are one of these areas needing to be more robust and/or improved upon when building sustainable power. XAT has one again teamed up with industry giant MANLEY to bring our new 1UZ vvti, 2UZ, 2UZ vvti, and 3UZ Stainless Steel valve kit to market! These valves are available in stock size, .5mm oversized, as well as 1mm oversized. Full stainless steel construction with a swirl polished finish for the best available fitment and performance factor for you, the valued XAT Racing customer. 

These valves come in a complete kit of 16 intake and 16 exhaust valves for one engine. 

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

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!

As it turns out, not all UZ power steering pulleys are the same! Some of them are not serviceable. Additionally, the 98+ (VVTi and all 2UZ engines) use a different style pulley from the earlier cars.

Please note some UZ V8s come with a fixed, press on pulley to their power steering pump. If you have one of these, you will need to swap your power steering pump for one that has a hex nut retained serviceable pulley. We strongly recommend checking what you have before ordering, and feel free to reach out to us with any questions. They are otherwise interchangeable and not too difficult to source!

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!!

Although this is one of the most universal parts we sell, it's also one of the most interesting, and one of the few that we sell that has FAA approval for aircraft use! Most people just buy whatever oil filter they find and toss them after use. There's a better option however, especially if you plan on owning your vehicle for many years to come! 

Made in the USA with a billet aluminum housing and a stainless micronic medical grade mesh filter element that is easily serviced and cleaned, this is a great long term solution for your cherished ride. There's a number of advantages that come with using a high quality filter like this, instead of a generic spin on replacement.

• Easily tell the condition of the oil in your engine with every oil change. Instead of destroying an oil filter each time to inspect the contents, you simply wash out and reuse the same filter element.
• Filter element is reusable countless times, and easily cleaned with brake cleaner and/or soap and water
• Filter element includes a built in magnet to trap ferrous debris from circulating through the rest of your engine's oil system
• No more trying to loosen an overtightened oil filter! Every spin on filter includes a matching oil filter cap socket to easily loosen and remove, so no more fumbling and struggling with a filter that refuses to come out.
• As time goes by, oil filters become more and more expensive. Do you think your favorite oil filter will be the same price in a few years? It wont take long for this to pay for itself!
• Apocalypse proof! Even if supply chains get interrupted, you can keep on truckin' without having to worry about sourcing a replacement filter for your engine.
• Even if you miraculously somehow manage to damage the filter element, replacement ones are readily available and not expensive
• Better oil flow than regular paper filters, meaning less start-up wear
• Have more questions? Check out this extensive FAQ: https://kandpengineering.com/faqs/

Fits most engines we specialize in! Including 1JZ, 2JZ, 1UZ, 2UZ, 3UZ, 1GR, 2GR, 3GR, 4GR, and so many more

After plenty of market demand, we have finished this ZINC CHROMATED set of brackets to mount LS460 / LS600h / LS500 brake calipers to any MkIV Supra, SC300, or SC400!

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 2007-2020 LS460, LS460L, LS600, or even the new 2020 LS500 fixed 4 piston brake calipers, plus 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 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.

Brackets fit:
☼ 1993-2002 Toyota Supra
☼ 1992-2000 Lexus SC300
☼ 1992-2000 Lexus SC400

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

Also fits:

☼ 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

Pictures show the RWD K17 type caliper being used. The AWD N18 caliper has the same mounting hole locations, but we do not support fitment as it would use a different rotor. You will need the K17 caliper for direct fitment

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.

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 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. 

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 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 

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 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
