A80 MkIV Supra 93-02 (JZA80)

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 J3 bellhousing (usually from 2JZGTE A340E automatics). 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. 

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, you will need the specific CD009 flywheel made for this application.

The twin disc setups include their own flywheel, but will retain the factory 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

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 1JZ or 2JZ swap, or simply adding a manual transmission to your already existing JZ powered vehicle (Supra, IS300, SC300, GS300). 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 doing it right the first time.

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.

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

Looking for a clutch for this adapter plate? 

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.

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.

Not every customer wants to replace their proven factory ECU, nor do they have to. With the ECU Master Digital Tuner III, you maintain your factory computer and install this as a true piggy-back device. Meaning your factory computer controls all the entire car as usual, EXCEPT you now gain control over all the parameters below to off true tuning in an easy to use graphical user interface.

This unit comes with a built-in 4 bar map sensor so you have the ultimate piggy back tuning device. Easy to use, easy to set-up with an amazing amount of engine control.

The ECU Master is produced in Europe and is sweeping the Continent by storm. For Supra owners familiar with the HKS VPC/GCC alphabet soup combination that powered many Supra's to 800HP, this replaces that type of device and then blows it out of the water with finite control of not only fuel curves, but also ignition!!

Features that boosted car owners love on this unit, "launch control", "boost control" "MAF to MAP auto conversion"

APPLICATION: 1993-1998 Supra 2JZGTE (Turbo), 1JZGTE, and 2JZGE (Non-Turbo), IS300, GS300, SC300, etc.

PLEASE CHECK AND VERIFY (MATCH) THE PLUG YOU HAVE ON YOUR ALTERNATOR

This alternator is 100% plug n' play, direct fit, with no adapters, spacers or rigging like other kits. This is not a Sequoia alternator, which does require modifications to fit.

As you may know, the stock 1993-1998 Supra alternator provides 90amps/105amps (6sp/auto) of current flow at maximum output. When you install electric fan's, a cranking stereo system, and other electronic gadgets this presses the factory alternator to it's limits.

In some situations with the air conditioner running, electric fans going, dual fuel pumps, and more, there is simply not enough current to keep the battery at a constant state of charge. If you mix-in a large current draw from car stereo amplifiers, your electrical system will stop producing enough current, voltages across the system which drop to the lower end of the scale, and major issues can (and will) happen!

The last thing in the world you want is your aftermarket equipped 2JZGTE running big boost on multiple fuel pumps with all your other goodies on and then lose some current to the fuel supply! As Goose said to Maverick in Top Gun, "this is not good, Maverick."

We have looked for quite some time for an upgraded alternator that was robust, had increased current capacity, good-looking, cost-effective and would fit properly in the 1993-1998 Toyota Supra! Well, good news is that we have just the units! Our 155amp HOT RATE alternator kit is now available. The alternators are tested HOT, which means the output is guaranteed during typical automobile standard conditions. Most every other manufacturer releases their current ratings COLD, which can change the current output vs. hot by 10-15% simply on resistance losses at higher temperatures.

Fit and finish are excellent and it is a plug-n-play installation.

These units do not require a core charge. We usually stock these, but even if out of stock, build-time is only 72 hours. Six month warranty.

* Custom hand wound heavy gauge stator with high temp. insulation. Fully re-manufactured.

* Highest quality Internal electronic voltage regulator.

* Oversized bearings with high temp. grease for durability.

* Heavy duty rectifier plate with high amp diodes.

Our alternators are hot-rated, not cold-rated like all the other guys, which translates into, real-world amperage ratings.

These units are completely re-manufactured from original units (see above bullets for highlights)internals rebuilt and then the magic begins. As with any alternator they produce current based upon the coil windings and rpm's. The coil windings is where the current capacity is created, so it is based upon the capacity of the wire and number of windings on the coil.

Without over simplifying the process, we simply use a higher current (and more expensive) wire and provide additional windings inside the unit. The higher quality wire allows more current and heat to be handled, and the increase in quantity of windings increases the overall capacity. Then the internals are matched with higher capacity components for a matched-internal device with external results.

Bottom-line: you get a re-manufactured alternator, designed to produce more clean current then the factory original.

For 1JZGTE owners, this is NOT the 2JZGTE alternator, it is a 1JZ with the correct round 3 pin plug for the JZA70 Supra and is rated at ~140 AMPS. 50 more amps than you stock unit! If your 1JZGTE alternator is from a Soarer or Chaser, then please select the appropriate version from the drop down menu. 1JZ owners, please include what style connector your harness has, round or oval/rectangular

Application Note: This alternator will fit all 1993-1998 Supra Turbo and Non-Turbo Supra's, both automatic and 6 speed, Japan Spec, UK Spec, Euro Spec and US Spec. Direct fit, period.

International shipping: You will notice we have an international shipping option available in the drop down menu. While we cannot quote every country with this, it is good for much of the UK, Australia (eastern) and a few other nations. If you order the international option and for some reason the shipping is a bit more, we will notify you for your approval.

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!

Clean up your engine bay with the NEW Powerhouse Racing Billet Oil Filler Cap! This cap is made from billet aluminum and has the PHR logo engraved (black edition is laser etched) into it! These caps feature a raw machined finish, or optionally, a black anodized finish. Looks great with stock finish, polished, painted, or coated valve covers!

PLEASE NOTE THIS FITS 1JZ AND 2JZ ENGINES, HOWEVER IT WILL NOT FIT ANY 7M OR UZ ENGINES (1UZ, 2UZ, 3UZ). They use a threaded screw instead of a sprung lug setup.

With the discontinuation of the TRD Thermostat some years ago that left only a single thermostat option for the 2JZ engines aside from stock. I'm happy to announce the newest release from PHR, their new racing thermostat!

This unit is a direct fit in your your 2JZ equipped vehicle with an opening temperature of 68 degrees celcius or 155 degrees. These are offered at a very reasonable price at less than $49.95, they are a great addition to ANY cooling system upgrade on your 2JZ.

Fits other Toyotas as well!

The PHR Cam Gear Bolt with Stainless Washer is the perfect finish to your engine bay. Why have a beautiful set of cam gears and ruin the look with ugly factory bolts? The PHR Cam Gear Bolt Features a tapered washer which protrudes around the bolt to give a fantastic look and clean finish. This bolt is class 12.9 which exceeds the strength of the factory spec!

This is ONE bolt and washer. If you have a VVTi engine, you will NOT be able to use 2 of these. If you have a non-VVTi engine, you will need 2.

Please note these are currently built to order with a roughly 6-8 week turnaround time. Sometimes quicker, sometimes 10-12 weeks. We can't currently make any promises and are doing our best to keep up.

If you are running a V-band inlet turbo, please let us know which one so we can weld the correct flange to the manifold. We strongly suggest finding the correct flange and sending it in to us, since there's an assortment of different v-band flanges used on the market.

Dual wastegate manifolds may need to be modified to fit your chassis/project

For years people have been asking why you must pay $1200+ for a turbo manifold. While we appreciate it takes time to design and fabricate a manifold, it doesn't require a $1200+ price tag.

Our goal was under $1000 for a world-class hand-made manifold for the Supra community, which we have been a part of longer than any business on the planet. We also include a 3 year warranty on all ProSeries exhaust manifolds sold!

Our 304SS tig welded 2JZ exhaust manifold scavenges like none other on the market, with efficient runner designs and a proven collector, which fits smaller frame to mid frame turbos from Precision, Garrett, Borg Warner and more.

They are finished in a brushed-stainless "raw-look", but we can ceramic coat them at extra cost, if that is what you require. They are robust, handle heat cycles correctly and are guaranteed to perform.

The No. 1 runner is designed to provide maximum clearance for larger compressor cover turbochargers, while at the same time providing for an efficient overall layout. If you plan on running a larger turbocharger than an S300 series for instance, we also make a mid frame manifold instead.

ProSeries turbo manifolds are offered in un-divided (standard) and divided for those wanting to run twin scroll turbos, as well as Quick Spool (QSV) and Borg Warner EFR Non-Gate designs.

ProSeries turbo manifolds are hand-made in a jig (to offer consistency) and have amazing welds, and the fitment is outstanding. The standard sized runners are 1 5/8" inside diameter and utilize .080" wall thickness stainless.

This design allows for higher velocity exhaust energy, while still maintaining significant flow. These manifolds perform outstanding up to 1250rwhp. We have multiples customers making power numbers over that level, and running 8 flat 1/4 mi times with our manifold.

Inside Tubing Diameter: 1 5/8"

Wall Thickness: .080" (2mm)

If you require a TiAL, Precision, Turbosmart gate flange, or other branded V-band flange welded in (no 2 bolt or 4 bolt ones), this is available as an option in the drop down menu. Please let us know which wastegate you will be using.

When no wastegate flange is selected you will receive the manifold with the standard length wastegate tube "open" to mount whatever you want.

* Quick Spool Valve Turbo Manifolds are Available. Please see our other item listing for that specific version *.

* Our 3-year no questions covers any manufacturing related defect, including all welds and through cracking. The no questions asked warranty is for the original purchaser only. Micro-cracking of external welds in heat-cycled stainless has no affect upon performance.

Please be aware that there may be fitment issues with the dual gate setup in some cars. Although we can weld the wastegate flanges on by request, please note that we cannot guarantee fitment with your setup, as minor modification will most likely be needed.

Fitment will also be very tight with the Mk3 Supra frame rails if installing in an A70 chassis. In most cases, you will have to modify the frame rails/chassis, as there's not much room for fitment regardless of manifold used. Very little persuasion is required, but this is inevitable with our manifolds as we make our manifolds to fit as many different chassis' as possible. You will be better off with slightly modifying the chassis than compromising manifold design.

As with pretty much all tubular manifolds for these engines, you can expect to either modify existing mounting hardware or use the shorter hardware kit we offer. Again, the only way to feasibly make these manifolds with thick walls and proper runner design is to have a tight fit on the flange. This is much more preferable to compromising manifold design.

At maximum width from the head flange of the manifold, this is at its widest at about 10.75 to 11 inches, give or take

Since TRD has discontinued theirs, and Megan no longer sells any, factory Toyota might be the only way to go for your build! Quality solid mounts are readily manufactured by places like PHR, however these are not ideal for a car that rarely leaves the street. Please check availability with us before ordering

We don't always have a set in stock, so please reach out to us beforehand to verify wait times if you need a set posthaste. Price is for both sides

Please expect a 3-4 week wait time as these are custom made to order harnesses

We're big fans of Link ECU at XAT Racing! With all the features (and often more) that AEM ECUs provide, but at a better price, Link has quickly become a favorite of many tuners worldwide. Plus, Link ECUs are regularly available in stock, and AEM has discontinued their lineup!

This listing includes the custom made to order harness to make your Link G4+ or G4X series EMS "plug'n'play" to your car. Please select your application above, as well as any extras you might need to complete your build. Thunder ECU and sensors not included with base price.

Please contact us with any questions or inquiries!

XAT and PowerHouse Racing are happy to offer the Billet Aluminum Lightweight Pulley Kit for the 2JZ and 1JZ engines! Precision machined from solid aluminum, this is the finest pulley kit available. Reduce rotating mass and keep accessory speed where it should be, not underdriven. That's right, these are stock diameter pulleys that won't end up undercharging your alternator, slow down the water pump or make your power steering heavy, but still reduce rotating mass!

Kit includes:
☼ Power Steering Pulley
☼ Water Pump Pulley
☼ Alternator Pulley


Optional:
☼ Idler Pulley
☼ Water Pump Pulley Cover

The PHR Billet Aluminum Pulleys are made of 6061-T6 Aluminum. The idler pulley features a precision bearing for lifelong performance and reliability. Although the bearing should NEVER fail, it is still serviceable.

These are a direct replacement for the factory pulleys, no new hardware or spacers are necessary. They are the same diameter as the factory ones, and do not require a belt change!

Fits any car equipped with a 2JZ or 1JZ engine with e-fans or clutch fan water pump (does NOT fit with the hydro-fan), not limited to:

☼ 1993-2001 Toyota Supra
☼ 1992-2001 Lexus SC300
☼ 1989-1992 JZA70 Supra (or any JZ Mk3 swap)

☼ 1998-2005 Lexus IS300
☼ 1991-1997, 1998-2005 Lexus GS300

Please note that the IS300 and 2GS GS300 use a slightly different kit

Is your 2JZ having misfire issues at higher boost? Are you tired of constantly swapping out spark plugs and regapping them to ridiculously small levels?

For those running higher boost we've found that our King Spark kit is the best overall solution for the issues mentioned above.

We start with the very best OEM ignition coils ever made, bar none. These have supported well over 1000 rwhp on all sorts of different cars (including the fastest Mk3 Supra in the world) and can run with plenty of dwell. A great replacement for old failing stock ones!

We provide everything you see in the photo's, mounting brackets, wiring with connectors, either tested used or new (your choice) and a set of solid instructions for the mounting and set-up of your LQ9 King Spark system.

Optionally available is whats we've found to be one of the best plugs is our NGK Iridium spark plug (6 plugs). We supply these in -7 heat range, but other options are available if you have a specific preference.

These are designed for resistor plugs only, do not use a non-resistor plug with the King Spark system. The standard plug being used is the NGK or equivalent BKR7E, but other options and heat ranges can be used depending upon your modifications, compression, fuel requirements, etc.

If using an NGK you want a plug with the "R" in its nomenclature as this designates a 'resistor' plug.

Minor wiring required, but with our detailed instructions this is a do-it-yourself proposition

These fit perfectly in 2JZ-GTE and 2JZ-GE engines. 1JZ engines require some modification for them to fit in the valley.

If you opt for the Iridium plugs, let us know which heat range you need as well

Installation is not plug-and-play, but involves connection of only 8 wires to the igniter's two connectors. The igniter and the stock coil harness are eliminated. Installation instructions are included.

Please note that the GE heads, both VVTI and the distributor types, require a front facing intake manifold to utilize these coils, as the middle two coils do not fit under the Y-pipe throttle body.

If you have GTE valve covers on a GE head, the GE bracket will require longer standoffs to fit.

If the kit is being installed on a JDM/Asian Supra or Aristo, A Tachometer adaptor such as the Dakota Digital SGI - 8 or MSD-8920 will be required to restore tachometer functionality, as the tach on these cars is driven from a high level output from the (deleted) igniter.

These coils will work with the stock GTE ECU, but you would need an IGF box to synthesize the required IGF signal back to the ECU.Please note the coilpacks are NOT included with the base price 

If you're looking for a custom one off piece, we can have one made with your design! Please reach out to us and let us know what you're looking for. This is for GTE fitment valve covers only.

This solid billet aluminum valve cover is fully CNC machined and hand polished to a mirror finish, perfect for any show! It also leaves the cam gears uncovered, while covering up the coilpacks at the same time, for a more "race appearance." Engraved with the Powerhouse Racing logo, Supra script logo, or available blank with no logo for a show appearance. Please choose desired option from the drop down menu!

The black edition is fully CNC machined and anodized Black with machined accents, making it perfect for any show! Leaves the cam gears uncovered for a more race appearance while covering up the coilpacks at the same time. Engraved with the Powerhouse Racing logo and "2JZGTE Turbo" or 2JZ NO SHIT.

For a limited time, we're also offering everyone's favorite "The Fast and The Furious" quote, "2JZ NO SHIT" on certain Black Edition covers! Let the world know what you're running, how much you've spent in overnight parts from Japan, and that it doesn't matter if it's an inch or a mile, winning is winning.

Matches the Black Edition Pulleys and Oil Cap, available separately

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. 

Our new favorite injector! We use these on all of our builds and never had any reported issues. Finally, a quality injector without breaking the bank!

We sell these as complete drop in, plug n play injectors for your JZ engine. 2JZGTE engines will need a top feed fuel rail (we usually recommend PHR). 2JZGE engines with air assist (early non-VVTi USDM mostly) will need the Radium injector seat kit, available via the dropdown menu.

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.

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 and is meant to match the front kit we also sell! 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!

This listing includes the brackets and hardware to mount. We give the option of piecing together the rest of the kit yourself, otherwise you will need all of the dropdown menu options for 100% bolt on. These may not be legal for normal road use in your jurisdiction. We recommend checking before purchasing.

Caliper, mounting bracket, pads, and rotor weigh a combined total of 21.6 lbs

IMPORTANT: because of the size of the internal drum e-brake these cars have, you WILL LOSE E-BRAKE capability unless switching to the Project Mu shoes or a 2nd caliper setup.

Brackets fit:

And possibly others! We have not confirmed fitment on any other chassis/vehicle.

If you are switching to an after market exhaust manifold on your 1JZ or 2JZ engine, then many of the manifolds require a shortened exhaust stud to provide proper fitment.

We have custom sourced genuine Toyota parts that do the job, and have included the correct nut for them as well.

You will receive:
☼ (8, 10, or 12) Exhaust Studs Genuine Toyota
☼ (8, 10, or 12) Nuts for exhaust studs genuine Toyota

We keep a set ready to ship out at all times! Please select the engine you have so we can send the correct quantity.

2JZ-GE, both VVTi and non, will need 8 nuts and studs
1JZ-GTE VVTi will need 10 nuts and studs
1JZ-GTE non-VVTi, 2JZ-GTE, non VVTi, and 2JZ-GTE VVTi will all need 12 nuts and studs

Need the reverse Torx socket in 3/8ths drive to remove the old ones and install the new? We can get that too!

The studs protrude 22mm (7/8") from the head flange when installed. In the pictures for representation, the longer, rusted studs are the factory 2JZGTE ones.

*Various differentials or transmissions need the smaller or larger bolt pattern, so please measure on your actual transmission and/or differential flange. 

This U-Joint Adapter is the perfect solution for adapting your Toyota 3-bolt differential flange (Supra, GS, SC) to a driveshaft utilizing a 1350 4-bolt U-Joint flange.

Includes all necessary hardware for ease of installation.

Switching over to a single turbo? Still have ugly heater hoses running over your valve cover? Clean up your MkIV A80 Supra engine bay with this hose kit from PHR! Comes with four stainless worm gear clamps to ensure a leak free install.

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!

Asymmetric pistons have been slowly gaining popularity in the aftermarket world. The idea is that the skirt can be beefed up as necessary on the thrust side of the piston, but the trailing side does not need as much reinforcement. With this design, the piston can be made with less friction, which means more power and better mileage!

These pistons come with HD2 asymmetric skirts, lateral gas ports, and .200" wall wrist pins

The girdle kit includes required ARP hardware, and fits any 1JZ or 2JZ engine, GE or GTE! What is it for? A girdle will remove 'swing' in the main caps. The swing in the block will be most in the middle of the engine. The girdle will also act as a partial windage tray. This girdle is compatible with all 1J and 2J engines and all sump types.

If you are using the OEM main caps, the girdle will rest on them. Your engine shop/builder should machine the provided spacers to the exact same height. If using billet main caps, you can let the girdle kit have a tiny amount of space from the caps, but spacers may still require modification to fit.

We have confirmed fitment with Titan and Induction main caps. Some minor milling may be required on the caps as well as spacers to fit the girdle properly.

The Power House Racing high flow fuel rail for 2JZ features a 17.5mm (-8AN) internal diameter aluminum rail for the most flow possible! Capable of fuel flow to feed over 2000 Horsepower.

The PHR Fuel Rail Kit Includes:
High-flow fuel rail
Mounting brackets
Fuel Injector Bosses
One -8AN side inlet fitting,
One -6AN side outlet fitting,
One -6ORB plug for the center port.

Comes in a Black Anodized Finish. This anodizing offers protection against exotic fuels and alcohols, so it's E85 ethanol ready right out of the box!

Must be used with 14mm injector top. Denso (HKS / GReddy style 11mm) fuel injectors will not fit this large diameter fuel rail. We recommend Victory Motorsports or Injector Dynamics injectors with these fuel rails, but there are many injectors that will work.

Will work with factory intake manifold or Virtual Works intake manifold. Will not work with Hypertune Intake Manifolds.

If you're piecing together your own kit, or maybe just swapping out a turbo, XAT Racing has you covered! This listing is for a single turbo oil feed setup with a -3 or -4 sized line. Reach out to us with the turbo youre using and we can make sure you get the right parts! We include the GTE block side fitting and turbo fitting as well, depending on what you are running.

We typically use -3 sized lines on most turbos, except for Borg Warner AirWerks (SX series) turbos, which get a -4.

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.

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.

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.

Looking to update your Supra's interior? We have just the thing! Many options are available, including synthetic or genuine leather and stitching colors.

Please keep in mind these are made to order, so you can expect a few weeks wait time for them to be finished up and shipped out. We also cannot 100% color match to your interior. Every car has had a different amount of use/wear, exposure to UV, chemicals, etc., so we are unable to get it exactly the same as what you have. The color swatches are the different options we have. If matching colors is a concern, we recommend getting all of the interior options we offer at the same time, including front/rear seats, door arm rests, center console, and shift boots.

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 

Finally an overflow you can be happy to have in your engine bay! The PHR Radiator Overflow for the MKIV Supra tucks in close the the headlight, making room for 4" intercooler piping or a full size battery to fit up front (PHR will soon be offering a battery tray to fit a group size 26 battery, stay tuned). No more tucking ugly plastic overflows and pretending it's not an eyesore. The PHR overflow features a CNC Formed aluminum tank body with a billet cap. Please keep in mind this MkIV Supra chassis specific fitment. It is not meant for similar chassis' (SC300/Soarer) without modifications.

Installation notes:

Hose from radiator should attach to the bottom port on the overflow tank. The top port can just vent or can have a spillover hose run underneath the vehicle. If running hose please do not let the spillover drain in front of the tires.

The PHR Radiator Overflow is not designed for use with a OEM size (Group 24) battery or the OEM battery tray. The PHR Radiator Overflow is perfectly paired with a PHR Billet Battery Tray or PHR Battery Relocation Kit. If you would like to retain a OEM size battery, you will need a new battery tray.

Price is for 2 package for 1 axle. If you need a set for the whole car, front AND rear, you will need to select that from the dropdown menu.

Power House and XAT Racing are glad to offer the Stainless Steel Braided Throttle Cable for 1993-98 Toyota Supra and 1992-2000 Lexus SC300 and custom lengths for other applications! 

This throttle cable is made of beautiful teflon-lined lubricated stainless cable with billet CNC ends and cable stops. This is the perfect upgrade over you plain-looking factory throttle cable. Available for XAT Royal Chamber, Non-Turbo, Twin Turbo, Hypertune, and Virtual Works intake manifolds.

Throttle cable assembly instructions available upon request. For custom applications, please see the above picture for needed measurements. We will need the lengths in blue and in red.

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!

For those that need more electricity than our 200 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.

The PHR Billet Isolating Engine Mount is the ultimate solution without compromise. Full solid mount will always be accompanied by increased vibration and noise transfer. This innovative isolating design help cut down that transfer while keeping the rigidity that you want for your race engine. More aggressive than the TRD variation without committing to full solid mount. Despite the 2JZ being a very balanced engine, a full solid mount will always be accompanied by increased vibration and noise transfer. This innovative isolating design help cut down that transfer while keeping the rigidity that you want for your race engine. 

These are beautifully CNC-machined from 6061 aluminum with a 70A Durometer rubber cushion separating the two ends. You're going to shed a tear hiding this away in your engine bay.

Mount is serviceable meaning you can inspect and replace the rubber cushions inside. These can be purchased from PHR separately.

Price includes both mounts for both sides! THE SUPRA VERSION IS DESIGNED AROUND THE S1 (EARLY MODEL) ENGINE BRACKETS** SC300 and Late Model Supra Brackets (97+) will not work. If you have a 97+ Supra or any year SC300, you will need the billet mount brackets as well. The factory cast mount brackets have been discontinued.

Powerhouse Racing has always been on the top of the world in creating solutions to common problems that occur with the 2jz engine. One common issue is the timing pickup will often separate from the main timing belt gear and spin independently of the timing gear, causing a trigger/sync error. This will cause running and timing problem. As a solution, they have built a one-piece gear to so that you would never have to face this issue.

Rather than welding the factory gear (which typically ends up messy), PHR has made the move to CNC a single-piece steel timing gear to offer an even stronger product. Zinc plated to prevent corrosion.

**NOTE FOR VVTi*** A 2JZ utilizing the VVTi system has a different timing gear with 36-2 tooth setup. It is a single piece and does not suffer from the same potential seperation issues. Meaning you may not need to change the gear on a VVT-i setup. However, the teeth on the VVTi version are brittle and do commonly break, so they have developed a billet version. It also has more defined edges which can provide a cleaner signal. 

Some racers choose 36-2 for more resolution on their timing signal even on a non vvti setup. If youre running a standalone ECU, we strongly recommend swapping over to the VVTi's 36-2 tooth gear for the same price and getting a better read/signal for your computer!

These toe arms are essential pieces for racing applications. They keep your rear wheels locked in line without radial shimmy upon launch. In cornering they remove neraly all toe flex and add stability and predictability.

The PHR Toe Arms are constructed using swaged steel tubes, chromoly heim joints and 4130 Heat Treat spacer bushing and taper sleeve bushings.

With big single turbo kits, one of the biggest problems with installation is the routing of the factory manifold. The Powerhouse Racing Lower Waterneck Rotator is the ultimate solution for turning your waterneck away from your turbo manifold on your 2jzgte.

With the lower waterneck in the factory position, there are two problems:

First, the waterneck gets in the way of the runners on many turbo manifolds. See picture below.

Second, the waterneck is blocking the ideal routing for compressor outlet to the intercooler piping. See picture below.

The PHR Lower Waterneck Rotator moves the waterneck out of this terrible location allowing the manifold to fit properly and the compressor outlet to be free of obstruction. See picture below.

NEW REVISION!!!

The thermostat has two functional parts to it: the thermostat valve itself, which opens at a certain temperatures, and at the same time, a valve that closes off the radiator bypass hole when the thermostat opens.

Normal operation of the thermostat and waterflow is as follows: when the thermostat is closed, the bypass hole is open. This flows the water directly out of the head and back to the waterpump at low coolant temperatures, like during warmup and no water flows through the radiator. Once the coolant reaches the thermostat opening temperature (usually 180 degrees or 160 degrees), the thermostat opens and the bypass hole is closed off, forcing water through the radiator, and cooling it down.

Take a look at the following picture to see what hole needs to be blocked off when the valve opens.

With other brand waterneck rotators, and even the earlier version of the PHR lower waterneck rotator, positioning of the thermostat has had to be moved away from it's proper location in the housing.

With these designs, the thermostat is moved away from the bypass hole to accommodate the rotator itself, and the thermostat installs in the lower waterneck boss. This new position makes it so the bypass hole can never fully close, so even when the thermostat is open, the bypass hole is not closed and a large amount of the water is not allowed to go through the radiator and be cooled. This reduces the efficiency of the cooling system.

The NEW Powerhouse Racing Lower Waterneck Rotator solves this problem. The position of the thermostat remains in the factory location, allowing the thermostat to close off the bypass hole like it is supposed to and moving flow of all the water through the radiator, maximizing cooling system efficency.

See the picture below to see the position of the thermostat in the NEW Powerhouse Racing Lower Waterneck Rotator:

You have two choices when installing your new rotator when it comes to the hose. You can trim your OEM radiator hose, or you can use specialized silicone hose

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

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

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
