Brand new OEM rear main seal for all 1989-2010 UZ (1UZ, 1UZ VVTi, 2UZ, and 3UZ engines), UR (1UR, 2UR, and 3UR) and 1997-2017 1GZ V12 engines! Keep your oil in the engine, not leaking out!
As we continue to build the Toyota V8 market more and more, we also continue to push the edge and develop the best new parts. Check out the XAT Racing exclusive dry sump oil pan and oil pump bracket! This oil pan will fit any UZ engine (1UZ non-VVTi, 1UZ VVTi, 2UZ, or 3UZ) and is made to use the Moroso dry sump oil pump. We modeled this kit after the actual setup the original TRD UZ V8s used in the early 00s in IMSA!
Please note, this is not a complete bolt on kit. Each kit would need to be unique to each chassis. Expect to sacrifice your A/C compressor for this, as it mounts the oil pump where the air conditioning compressor is normally located.
We made these headers specifically for a customer's 1984-1989 1st gen 4Runner that we swapped a 3UZ into. With how tight the space is around the engine, especially near the body and steering shaft, options are limited when it comes to exhaust manifold fitment.
Fortunately we have a solution to help get you started! You'll need to finish the rest of the exhaust plumbing on your chassis with the engine 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.
Depending on your specific application, you might need to modify these to fit your project better. The important thing is this will get you closer to where you need to be!
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. Made in the USA!
Not everyone needs a huge big brake kit. We've been able to source OEM Toyota brake pads for your 150 series Crown! No modification needed, and you can keep your stock wheels. Typically ships in 1-2 weeks or so.
Please send us your Japanese VIN so we can confirm fitment for you before ordering. There are multiple brake options for some of these vehicles.
Fits the following chassis:
‘Drop in’ PACALOY valve spring set to suit OEM retainers. Featuring Nano-peen and Gold nitride surface finish treatment, this is the highest quality 1UZ spring on the market.
80 lb seat pressure at 33.00mm installed height.
Coil bind is at 20.50mm
Our custom-designed CP piston kit can be ordered in custom compression ratio to suit turbo, nitrous, or N/A applications. CP Carrillo pistons are the premier piston in today's market! The custom forging is CNC'd to match ultra tight tolerances for high output engines. When the power goes up, so does the heat. Stock pistons are cast and cannot cope with the stress level of a race or high output engine. This piston kit comes with all eight pistons and includes pins, clips and rings. This item can be ordered for the VVTi version as well. Please select size and type from drop down menu. Made in the USA!
Please note these are custom made to order pistons. We do not stock these, and typical wait time is 4-8 weeks to produce. Since we have not found anybody to make off the shelf pistons for our engines, these have to be special order, and as such, are non-refundable. If there are issues with the order, we will fix them, but we will not take them back due to plans changes or changing your mind.
Full set of x16 stainless ARP bolts to bolt your exhaust manifolds to any UZ engine! We use these specific ones when installing PPE headers as it is much easier to do so than to line up on the factory studs
Please check stock with us before ordering if time is a constraint
Keep your car original and use the right parts the first time. Stick with OEM Toyota!
This is the grommet that sticks into the intake side valve cover and holds the PCV valve
Fits countless Toyota engines including JZ, UZ, GZ, etc.
Included with this listing is front accessory drive hardware that is still available for the 1UZ non-VVTi engines, all OEM Toyota parts!
Includes power steering and alternator pulley retaining nuts, lower alternator bolt, upper alternator nut, lower power steering mount nut, mounting bracket bolts, rear power steering pump to block mount bolts, belt tensioner pulley bolt, tensioner pulley mount bolts, center idler bracket nuts and bolts, alternator mount nut, and x4 clutch fan retaining nuts
Many of these will crossover to other UZ engines and parts. This is not a 100% complete list, as some pieces are discontinued or different depending on your model.
Pictured is everything included!
BC has joined the fight! Now available are standard forged 4340 steel H-Beam rods, which also come standard with ARP2000 rod bolts!
We use these on all of our in house UZ builds, and the majority of customer builds as well. Brian Crower is one of the few names in the biz that are high quality, low cost, and happy to develop and make parts for our UZ engines. An XAT favorite!
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. We use factory OEM head gaskets when possible.
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.
So you bought one of our various LS460 upgrade brake kits, have driven thousands of miles on it, loved it, and abused the crap out of the rotors. After a wholesome amount of wear and tear, your rotors have finally fallen below 28mm of rotor thickness, and it's time to replace those tron discs for a new start.
Say no more! These rotors are what we use in all of our LS460 5 lug brake kits, including our 2GS (GS300/GS400/GS430/SC430, Aristo), IS300, MkIV Supra, Celsior/LS400, and 5 lug 2005-2015 Tacoma. Price includes both front replacement rotors
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. Made in the USA!
The XAT Racing Lexus BBK comes with everything you need to bolt on this new brake setup, short of your favorite brake fluid. That includes calipers, rotors, pads, pins, anti-rattle springs, mounting hardware, roll center adjusters, brackets, and stainless braided lines. Made in the USA!
Calipers are sourced from a 2007-2020 LS460, LS460L, LS600h, and even the new LS500 4 piston fronts, RWD non-sport package K17 style. We exclusively use brand new OEM Lexus/Advics in this kit.
For discs, we use preferred DFC/R1 (since StopTech went out of business) 2008-2014 IS-F 360mm (14.2 inch) rotors, not the cheap garbage ones. They come cross drilled from the factory (just like the IS-F rotors are), though we have other bolt on options as well if you're going for a different style or preference. We've not heard of any issues with rotor cracking like some other aftermarket applications have reported.
Please note that calipers are supplied bare natural dark grey. At this time, we do not have a reliable consistent source for powdercoating calipers properly, so we recommend reaching out to places local to you
Although this kit uses DOT approved components, please note it is meant for off road use only. Proper installation is required, and all safety precautions should be heeded. Most parts are readily available, but expect about a 1 week wait for us to have everything together
Additionally, you will 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.
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:
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.
With no other quality options on the market (Megan Racing seems to not want to make parts for our cars anymore), we did what we always do and ended up making them ourselves!
These 30mm billet RCAs serve multiple purposes, including compensating your suspension when lowering your car and also give a bit more room to make our LS460 brake caliper kit 100% bolt on with no modifications needed!
FITS ALL 2GS cars (98-05 GS300, GS400, GS430), 1ST gen IS300 (1998-2005), S150 Crown Royal (JZS151, JZS155, GS151, etc.), 89-97 LS400/Celsior UCF10, UCF20, and Mark II/Chaser/Cresta X90 and X100 chassis. Made in the USA!
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. DOES NOT FIT RHD CELSIOR. Contact us for UCF20 and rollcage-mounted options. Please keep in mind these are often made to order and may have a 3-4 week 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! Made in the USA!
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!

We've been using these for years on our various Celsiors/Crowns that we've imported
It's not even just a "JDM tax." Here's a detailed version of the process:
First, you see what cars are available at auction. Cars typically are inspected before being listed, so any potential issues, flaws, dents, rust, paint chips/flakes/problems, etc. are typically noted. They are by no means perfect and able to find/report all of the issues with the car, and typically there's only 2-4 small pictures of the car shown. Thousands of cars are listed every day, so you are at the mercy of the inspectors and their judgment of a particular car. Depending on where the car is located, we may be able to have a closer inspection and have someone take a look at it for an additional fee.
The notes that are taken on the car will be posted up with the car on the listing, but then they also have to be translated. Since theyre usually hand written, your phone cant always translate them properly. Sometimes extra parts are included (like a full set of extra wheels), as the company auctions it exactly as the car was provided to them, however these may be taken away/tossed by customs. Keep in mind that the legal cars to import are all 25 years old, which means they will have 25 years worth of mileage, wear and tear, and potential issues. Fortunately, Japan is far, far better about maintaining their vehicles than Americans are.
Another note is that the appraiser might not know the car inside and out. They might not be a passionate enthusiast, or know a particular model very well. They might not have an eye for specifics that might differentiate one car from the next. It is up to the buyer to know what they are looking at and what they get. XAT specializes in a very specific few models, as we know these cars well. We've been able to develop experience and knowledge for them, inside and out. As such, we only import the best models and versions of these cars (Celsior, Crown, Chaser, Century, Mark II, Land Cruiser, etc.)
When you import cars, you have to pay whoever you get it from (usually an auction yard), sometimes storage, pay the broker to place the bid, make sure it's de-registered, get the export certificate, transport from the auction yard to the dock, dock for loading, transport to the USA, dock at USA for unloading, customs fees, then you either pay the dock for the privilege of picking up your own car, or pay a transport company to deliver it to your location. There are many steps in the process, and lots of different people involved in the logistics of getting it over here. Keep in mind you have also bought this car site unseen, and by the time it arrives, it might not be in as good shape as you expected. Most cars tend to look better in pictures, and your brain fills in the blanks. On average, it's typically 2-3 months from the time of winning the auction to actually getting the car in your possession. And that's if it's legal, not counting if you purchase a car that is not old enough yet, so it has to be stored in Japan first until it is.
Now that you have the car, you then have to get it legal in your state. In FL, if it can drive under its own power, it's legal...sort of. We don't have emissions testing like other states do. For starters, it needs to be inspected by the state (different office than the normal DMV).
So then you have to physically take it to one of just a few locations, most of which are not local. That means paying someone or trailering it to where it needs to be. We're lucky that it's "only" 40 minutes away for us. You cant legally drive it there for the inspection, as it has no insurance, no registration, no tag, etc. Driving it there illegally is incredibly risky, and could end up costing you the whole car!
Now that it's there, it has to pass inspection. Your local DMV most likely is not set up for this, there's separate places that are. During inspection, you have to present the proper customs forms, which have to be filled out properly by the department of homeland security, US customs, EPA, the shipping company, the export certificate that confirms the car has been de-registered in Japan, a notarized copy of the translation of the Japanese documents, etc. This process requires advanced appointment, dealing with government employees that hate doing their job and are miserable to work with, and never less than 2-3 hours out of the day. This is for each and every single car.
Once it passes, you have to go to your local DMV and obtain a title for it. VIN has to be registered, etc. It's a different process for JDM cars, as they don't have 17 digit VINs and they don't have stickers plastered over every door and body panel.
You cant register/tag it without insurance, so you need to find an insurance company that will insure the car. Once it's insured, and you get the tag, THEN it's legal to drive.
Just because it's legal doesnt mean it's road ready. XAT inspects each and every car thoroughly. We note any maintenance that has been done, and typically any maintenance that it might further need. Every car is meticulously detailed as well. I personally use a toothbrush and wet toothpick to clean all of the creases and body lines in between the bumpers, doors, around emblems, and even windows to get as much nasty gunk out as possible. We also wash every car with Toyota brand car soap (not even kidding), claybar every car, polish every car, shampoo/vacuum the carpet of every car, condition the leather of every car, and clean anywhere and everywhere that we can to restore every car to "almost new" status again! In some cases, decades of air pollution will have given the car a slight brown haze, so we do our best to remove that as well. It may take 20 man hours for each car to be truly ready for sale.
We dont import just any old JDM car that seems cool either. There are very specific particular models we target to bring over, and theyre always the best we can get, especially bang for the buck! For instance, with the 10th generation Crown, we do not bring over anything less than the 2JZ spec hardtop cars. The smaller sedan version with framed windows, we pay no attention to. We specifically target the earlier zenki models (1995-mid 1997) as they have the best platform to start with. Typically, we aim for Royal Touring 2JZ spec (with Toyota's first 5 speed automatic), or Royal Saloon G models, which include power rear seats, rear A/C, and nearly every other option from the factory. We dont even look at the 1G-FE or 1JZ powered cars, as theyre frankly not worth it.
When it comes to Celsiors, we stick to a few specific trim levels, depending on what car someone might have in mind. The B type is the more "sporty" option, with active TEMS shocks and suspension, while the C type has a comfy air ride that can be raised or lowered with a controller. We also occasionally get the eR spec, (European style), which includes leather, sunroof, and Autobahn tuned springs, shocks, steering rack, upper arms, bushings, etc. While you may see similar JDM cars listed for sale, often for less money, they typically are missing some of the best options these cars came with. And that's what we provide our customers with.
Another thing to consider: in Florida, you are only allowed to buy/sell 3 cars in any 12 month period without getting a dealer's license, which requires a brick and mortar location zoned for commercial etc. etc. That's an entirely separate process that has its own share of months and months worth of headaches. As such, we have to lease a specific physical location to run our business out of that is approved by the state, so we do have a bit of overhead to contend with.
XAT Racing is FINALLY a car dealer once again. We have gone through the necessary legal process to be a legitimate car dealer legally. We've risked many thousands of our own dollars out of pocket just to start the process.
Full engine gasket kit for your 90-97 1UZ engine! Fits SC400/Soarer, Aristo, Crown Majesta, and LS400/Celsior engines
We typically recommend replacing the included head gaskets with factory MLS 1UZ VVTi head gaskets
Wilwood Adjustable Single Pedal - Reverse Mount - 6:1
It's a clutch pedal! We use this with our UCF10 LS400 pedal mount bracket. Also can work with most other cars.
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
Breathtaking performance with ultra high efficiency – Bullet’s world first High boost upgrade for the 1UZ-FE utilising the HTV1900 Supercharger.
Forget the M90 or M112, this is the Supercharger to have nestled confidently on your engine. This kit has been developed to meet the needs of those 1UZ owners chasing a real world 250kws+ at the wheels. The Harrop HTV1900 is a Roots-type supercharger manufactured utilizing the latest Eaton TVS (Twin Vortices Series) rotating assembly. The Eaton TVS rotating assembly features twin four-lobe rotors, twisted 160 degrees. By comparison, the original Eaton superchargers (for example – the M90) features three lobes twisted 60 degrees. The fourth lobe and added twist, when combined with redesigned air inlet and outlet ports, creates a smoother, more efficient flow of air into the engine. In addition to improved overall efficiency, the Eaton TVS supercharger has improved noise and vibration characteristics as well.
The HTV1900 kit is a true OEM style kit utilizing the renowned Bullet High Flow cast intake manifold. From the CNC cut top plate to the unique Bullet high flow rear entry, the Bullet kit is unrivalled in engineering precision and product development. The HTV1900 delivers maximum boost from ‘off idle’ all the way to the redline, maximum torque at lower engine speeds and drastically reduced air intake temperatures when compared to the M90 and M112. The HTV1900 can support boost levels in excess of 15psi and with the increase in efficiency, produces unlimited high rpm power that easily outperforms any other 1UZ positive displacement Supercharger kit on the market. Guaranteed.
For maximum gains, Bullet recommends a complete standalone engine management system to take full advantage of this Supercharger’s potential.
Forget the M90 or M112, the HTV2300 is the Supercharger to have nestled confidently on your engine. This kit has been developed to meet the needs of those 1UZ owners chasing a real world 250kws+ at the wheels. The Harrop HTV2300 is a Roots-type supercharger manufactured utilizing the latest Eaton TVS (Twin Vortices Series) rotating assembly.

Please note the optional intercooler kit is NOT a complete kit. You will need to plumb the lines up to a heat exchanger, which will depend on your chassis/setup.
This will fit all UZ engines, however the non-VVTi 89-97 engines will have timing belt idler pulley slightly off . You would need to run a larger idler pulley to keep timing belt tension. Customers have reported using pulley part number 231016 though it may also need a spacer.
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!!
Pulley for UZ setups using the replaceable middle/center idler bracket instead of a hydrofan setup
Not sure if this is the right pulley for you? Put your application in the order comments, or email us before your order and we'll get you taken care of!
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.
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.
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!
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!
Please contact us for availability on the different rotor/caliper styles, as they go in and out of stock regularly!
Made in the USA! 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 BBK is specifically designed to use MkIV Supra TT rotors (323mm), 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.

Made in the USA! 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 (323mm), 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!

These are for off-road use only and are not meant for any on-road vehicles. Buyer is responsible for obeying all laws, local and federal. This are purely for testing to see if your cat has failed and is clogged.
You may get a check engine light/MIL/CEL code with these. Gaskets not included. We often use high temp gasket maker like Permatex ultra copper, ultra black, etc. as replacement gaskets. Made in the USA!
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
There's a number of brake pad options out there with different compounds and capabilities. We've found the best all around option and have been using these since our very first kit in 2019.
These pads are great for all uses: street, strip, race, drift, highway cruising, etc. Theyre dead quiet in all conditions and have great feel.
They also come with all necessary installation hardware. Many less expensive kits out there do not include all of the needed springs/clips, and some dont include any at all! Be wary of these kits, as you will no doubt end up spending extra time and money to source the individual parts you need separately. Or you can purchase this kit, which we typically keep in stock and ready to ship next day!
Save yourself the hassle and go with the option we selected!

The Lexus LS400 was a five-year, one-billion dollar investment for Toyota, designed to be the absolute epitome of luxury, complete with automatic features, California walnut in the interior, and even an integrated cellular phone. The designers thought of almost everything to make the vehicle the perfect flagship for the brand, but Air Lift Performance thought that a change in ride height was in order. Their engineers started on the Lexus LS400's suspension by adding exactly what their air suspensions are famous for -- giving you the maximum drop, 3.5in from stock without sacrificing performance. But simply getting you low was not enough for Air Lift Performance.
These kits are also about achieving the versatility that the common coilover cannot, eliminating classic lowered-car problems, such as bottoming out, with the touch of a button. They pride themselves on making sure that every Lexus LS400 kit that they build not only provides a great ride, but also handles the curves like a fine sports sedan should.
In front, the Lexus LS400 kit features double-bellow air springs over monotube, threaded-body shocks, which provide a comfortable ride and great body support during cornering or braking. The rear kit also features double-bellow air springs, providing the ability to air out 4.9in from stock
With 30 levels of damping adjustability, the shocks allow for a huge range of customization, with the ability to go from super soft to a stiff performance setup. As the leader in air suspension products for more than 65 years, Air Lift Company and its Performance division is committed to delivering quality parts that last. To ensure the highest quality, longevity, and customer satisfaction, the key suspension components have all been torture-tested to 1 million cycles on our in-house hydraulic test rig at temperatures ranging from -30 F to 150 F. With a one-year, unlimited-mileage warranty -- not to mention Air Lift Performance's best-in-class customer service and technical support, should you run into any snags in the installation process -- you can purchase this kit with peace of mind.

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.
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. Made in the USA!
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:
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!

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.
Don't bet your engine and cooling system on subpar cheapo parts, especially when the OEM ones are so inexpensive! We have fitment listed for all UZ engines, and even the 1GZ V12!
If you're in there doing maintenance anyways, why not replace with brand new factory parts and get another 20+ years out of them??
Typically takes less than a week to ship out! If youre uncertain, please observe the above pictures and match yours to the correct fitment.
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.
Fits most engines we specialize in! Including 1JZ, 2JZ, 1UZ, 2UZ, 3UZ, 1GR, 2GR, 3GR, 4GR, and so many more
StopTech Drilled and Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels and offer significantly improved braking performance. The unique cross-drilling and slotting aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance.
Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.036". World Products Man-o-War Block. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Looking for a complete brake upgrade for your UCF10 or UCF11 chassis? Here you are! We have finished the rear kit to match the front Wilwood kit we had developed for the earliest LS400 and Celsiors out there.
This kit uses the MkIV Supra TT rear rotors, giving you the flexibility to run whichever style you prefer (blanks, drilled, slotted, or drilled and slotted).
Please note these are meant for UCF10 (1989-1994) LS400s and Celsiors only. We have not confirmed fitment on other cars, though it may fit UCF20 chassis and GZG50 Century.
Made in the USA!
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 Rays wheels, etc.
Brackets fit:
☼ 1992-2005 Lexus GS300 / Toyota Aristo JZS147, JZS160, JZS161
☼ 1998-2000 Lexus GS400 / Toyota Aristo UZS160

And possibly more! WE HAVE OTHER BRACKETS TO FIT IS300/CHASER/MARK II/CRESTA/CROWN HARDTOP AS WELL!
You will receive 1 pair of brackets to mount both front calipers, as well as mounting hardware. Please note that we normally stock the brackets and rotors, however it may take 1 week to ship the calipers.
We have FINALLY released a rear kit to go along with this front kit! Our rear kit uses radial mounted LS430 (not LS460) rear calipers and Supra TT rear rotors. PLEASE NOTE FITMENT DIFFERS FROM THE FRONT KIT. NOT ALL OF THE ABOVE CHASSIS' ARE SUPPORTED FOR REAR 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.

W-Series Transmission Adapter for 1UZFE Swap FITS ALL KNOWN W SERIES ALUMINUM HOUSING TRANSMISSIONS
1UZ 2UZ 3UZ R-154 R150 R151 R150F R151F 5 Speed Adapter and Throwout Bearing Kit (also fits 1997-2004 Toyota V12s!)
Made in the USA! When we took a look at the previous generation of adapter plates, all we could see was room for improvement and higher quality. We wanted a plate that would mount PERFECTLY with zero slop. It needed to look good and perform even better. DON'T get stuck with an overvalued, sloppy plate that ends up costing you input shafts and has poor fitment. You can go with a less expensive alternative and end up with broken parts, or you can do it right the first time with us! No complaints with over 5 years of service.
This billet aluminum adapter plate reuses your factory 4 speed or 5 speed auto UZ bellhousing (1990-2004). It will require you to cut off the CD009 bellhousing, which gives MUCH more room to work with in most chassis. Alignment of the input shaft becomes dependent on this plate and not the quality of the bell housing cut, so worry not! This isn't like other kits out there. NO additional hardware/starter modification is required!
2005+ 6 speed auto bellhousings will not fit with this adapter.
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:
XAT Racing took a hard look at the concept, and decided to go all in with the "Toyota Big-Block" design. These V12s have started becoming more popular over the past few years! This will fit all versions of this transmission: CD001, CD003, CD005, CD008, CD009, JK41A, JK41B, JK40C, 1EA0A, and 1EA0B from the 2003-2008 Nissan 350Z/Fairlady Z, 2009-2020 370Z, Skyline V35 and V36 non-GTR sedan and coupe, and Infiniti G35 and G37
Our products are CAD designed with OEM blocks and transmissions on professional equipment by industry professionals. No bad measurements, no flame cuts, no warped discs, no nonsense. You should be using a 3/4" master cylinder in tandem with the TOB we use.
This is the missing link for doing a 1UZFE swap, or simply adding a manual transmission to your Toyota V8. Our CNC process for manufacturing the plate results in an extremely precise adapter plate, laser tight tolerances, and a focus on quality that has yielded a product that will produce less wear on the transmission and clutch. The adapter kits come with the needed pilot adapter and bushing as well. This is the tried and true kit from XAT Racing, except no imitations when it comes to Toyota V8s
Click here for install instructions
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.

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. Full set for your UZ V8! (NOT MEANT FOR AFTERMARKET RODS)
For higher HP builds (especially if your engine sees boost), we recommend upgraded rods as shown below, which include the rod bolts with them. These ARP rod bolts however are more than adequate for a fresh stock rebuild. ARP2000 bolts are also an option!
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.
You should not have to shave the head studs down for the scissor gears for the cams. We include washers for non-VVTi applications to make installation easier.
LISTING IS FOR HEAD STUDS FOR 1 COMPLETE ENGINE, BOTH HEADS!
Head studs need to be torqued to 70 ft/lbs
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. 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!

The added tensile strength of the ARP 2000 material lets you torque the studs down further, giving you even more protection from lifting the heads and/or blowing a head gasket, and is good for engines making 800+ HP
You should not have to shave the head studs down for the scissor gears for the cams. We include washers for non-VVTi applications to make installation easier.
Both (left and right side) head gaskets for your UZ engine rebuild! We only offer multi layered steel head gaskets for these, as they're tried, tested, and true. Please note if you do not select the OEM size, this order will be for Cometic gaskets. It often takes 8+ weeks for those to be custom made.
Please note the head gaskets are some of the only parts different between the different UZ engines, and you will need to select which engine you need these for specifically. Some of the few parts that do not interchange between the UZ engines are the head gaskets.
1UZ VVTi gaskets fit 1UZ non VVTi as well!
We offer an exclusive UZ engine torque plate for those that want to properly hone the cylinders on their Toyota/Lexus V8s! These fit 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 in the USA). 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.
They also get 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+ for these units, we thought we would bring it to the market for a reasonable price!!
You can expect one 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!
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.
We are also offering a rental service to use the ARP head studs that can be shipped with the plate. If you go this option, you will also be charged $15 to rent them, which we will subtract from the deposit once it is returned to us. Rental service is for 1 week only. Made in the USA!
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.
Please note these are only for the non-VVTi 1UZ engine. The 1UZ VVTi, all 2UZ, and all 3UZ engines should look at the SuperTech kit instead, as they have better fitment.
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 VVTi engines use a different kit.
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.

Our custom-designed JE piston kit can be ordered in custom compression ratio to suit turbo, nitrous, or N/A applications. Includes a full set of 8! JE pistons are the premier piston in today's market. The custom forging is CNC'd to match ultra tight tolerances for high output engines. When the power goes up, so does the heat. Stock pistons are cast and cannot cope with the stress level of a race or high output engine. This piston kit comes with all eight pistons and includes pins, clips and rings. This item can be ordered for the VVTi version as well. Please select size and type from drop down menu. Made in the USA!
Please note these are custom made to order pistons. We do not stock these, and typical wait time is 4-8 weeks to produce. Since we have not found anybody to make off the shelf pistons for our engines, these have to be special order, and as such, are non-refundable. If there are issues with the order, we will fix them, but we will not take them back due to plans changes or changing your mind.
Please note we are currently unable to supply these. Our best option right now is this listing: https://xatracing.com/XAT-UZ-Cams-regrind

We have released our custom made billet VVTi UZ race cams!! For those looking for serious power gains and pushing the limits of their Toyota V8, we now have a solution. Don't settle for stock cam regrinds, do a proper build with purpose built camshafts from scratch! Please choose your specific engine application from the drop down menu. We make different versions of these cams for 1UZ VVTi and 3UZ fitment, 2UZ non-VVTi fitment, and 2UZ VVTi fitment. This includes all 4 cams for 1 engine.
Forced induction (turbo or supercharger) cams have .428” (10.87mm) peak cam lift with 285 intake and 289 exhaust cam duration and 54 degrees of overlap. These are great for high HP N/A builds and forced induction projects!
Factory VVTi cams have 8.6mm and 250/260 duration, for reference
Cams can be ordered in VVTI and non-vvti versions., We now have fitment for all 98+ UZ fitment variations! These all will retain VVTi compatibility, and if need be, VVTi can always be disabled d own the road.
For the manufacturing process, we start with proprietary cast iron billets, CNC machine the lobes, and finish off with double heat treatment, 5160 induction hardening, and Tufftriding.
Please note you need to have your head machined to fit the race cams for lobe clearance. The forced induction cams do not require this modification.
The plugs at the end of the cams are included. Your scissor gears will also get reused from your original cams. The last 2 pictures show actual TRD heads and where they had to machine to install performance cams for example

Sizing ranges from mild street 264, all the way to insane, full built, ITB's, high comp, race motor 294 duration. For added revs, you will need our shimless conversion with buckets and new valves, but at this stage you can turn the heads well past 8K rpm. If you are building a stock engine with cams, full exhaust, piggyback or stand alone ECU you can use up to the 270 without having to go shimless, but you will need our upgraded valve-springs.
Please note these only fit the early 89-97 non VVTi heads. These are sometimes special ordered cams and may have a wait time on them of 3-plus weeks. Feel free to contact us for an up to date estimate before ordering

The XAT Racing Lexus BBK comes with everything you need to bolt on this new brake setup, short of your favorite brake fluid. That includes calipers, rotors, pads, pins, anti-rattle springs, mounting hardware, roll center adjusters, brackets, and stainless braided lines. Made in the USA!
Calipers are sourced from a 2007-2020 LS460, LS460L, LS600h, and even the new LS500 4 piston fronts, RWD non-sport package K17 style. We typically source a used set and rebuild them, though we can also get brand new OEM Lexus/Advics ones if you prefer.
We typically prefer the Posi-Quiet Centric/Stoptech pads, as they have excellent street performance and are not unnecessarily loud/squeaky once properly bedded in. Other options are available as well, if you prefer.
For discs, we use preferred Centric/StopTech 2008-2014 IS-F 360mm (14.2 inch) rotors, not the cheap garbage ones. They come cross drilled from the factory (just like the IS-F rotors are), though we have other bolt on options as well if you're going for a different style or preference. We've not heard of any issues with rotor cracking like some other aftermarket applications have reported.
Please note that calipers are supplied bare natural dark grey. At this time, we do not have a reliable consistent source for powdercoating calipers properly, so we recommend reaching out to places local to you
Although this kit uses DOT approved components, please note it is meant for off road use only. Proper installation is required, and all safety precautions should be heeded. Most parts are readily available, but expect about a 1 week wait for us to have everything together
Additionally, you will most likely need 18" wheels to fit over these. The only 18s we have found to not fit so far are some Enkei RPF1s and IS250/IS350 F Sport front wheels. We cannot make any promises on what else will not fit, however every other 18" wheel we have tried does fit over these brakes, including factory X-Runner wheels, Enkei NT03+, G35 Ray's wheels, etc.
Please keep in mind these are made to order with a build time of 4-6 weeks
This is a solution to avoid the supercharger belt when running a positive displacement blower on a 1UZ non-VVTi engine It uses the factory mounting location without the need of shim; the bolts are easy to access. It can accommodate two sensors. The bypass goes from next to the thermostat to the inlet. The crossover tube is made out of aluminum using an additive manufacturing process called SLM. The adapters are manufactured using 6061 T4 aluminum. It comes with 180° thermostat for a Porsche and the -6 AN bypass line is made from aeroflow components.
Our engines arent getting any younger! Keep your 1989-1997 1UZFE engine running fresh, smooth, and happy with these high quality ignition parts. With decades of experience, we have an idea of what works well, and offer this kit using the very same parts we've used on our own 1UZ engines. As always, we only use OEM quality parts or better!

We offer a number of other service parts as well for all UZ engines, so let us know what you're looking for and we'll be happy to offer suggestions and supply what you need!
It may be worth doing your valve cover gaskets and spark plug tube seals while youre in there also. We've added those options via dropdown menus for your convenience.
No cap? Get our oil cap for your engine, fr fr, ong. Or whatever kids say these days!
As with all of our machined products, we machine this at our shop in the USA with USA sourced materials. This fits nearly any valve cover that runs an M37x3.0 screw type oil cap, which is most Toyotas. However this will NOT fit the 1JZ or 2JZ factory valve covers. We are still working on the JZ version
Fitment includes but is NOT LIMITED to:

Unfortunately due to supplier issues, we've had to discontinue our billet UZ cams indefinitely. Our only other option is to re-grind factory cams to custom specifications.
Cams can be ordered for VVTI or non-VVTi engines., We now have fitment for all 98+ UZ fitment variations! These all will retain VVTi compatibility, and if need be, VVTi can always be disabled down the road. You will either need to send us your cams, or we can supply a core set for you.
For the manufacturing process, we start with proprietary cast iron billets, CNC machine the lobes, and finish off with double heat treatment, 5160 induction hardening, and Tufftriding.
Depending on how aggressive of a cam you choose, you may need to clearance in the head and bucket area for the bigger lobe to fit. Please note you need to have your head machined to fit the race cams for lobe clearance. The last 2 pictures show actual TRD heads and where they had to machine to install performance cams for example
