Check out a video of a V8 with these cams idling here!
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

We use these thrust washers on every UZ build!
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 with this remap tune service, you will need to send in YOUR ECU that we will modify for you. We cannot offer this service for 2001 model year IS300s. There may be considerable delays as well. EXPECT AT LEAST 2 WEEKS FROM THE TIME THE ECU HAS BEEN SENT IN FOR THESE MODIFICATIONS TO BE DONE.
Remap service is available for any 3UZ ecu, 2002+ 2UZs, as well as any GR and UR and some others SUCH AS THE IS300 2JZVVTI!!!!. Achieved are:
Zero trouble codes for downstream O2, cat converters, EVAP system optionally
Quicker a/t shifts
Modified a/t shift points vs speed and accelerator pedal (quicker downshifts in particular)
Up to 10% power and torque gain guaranteed for any 3UZ engine (95 or 98 octane)
Speed limit removal option
The standard, unmodified tune remains with the ECT power button on normal. When switching to ON, you activate the new tune. You can expect 10+ HP and torque on 3UZ engines throughout the power curve!
Our "standard" UZ Toyota V8 build has no problem holding 800 HP, but we also have options to do well over 1000+ HP!!
Standard short block build does not include heads (optional extras) but includes:
We also offer upgrades over the above parts!
We've been doing UZs for well over a decade, so we know these engines inside and out. We also know the importance of being able to customize your build and have the flexibility to run exactly what your budget allows.
Before pistons are ordered, we inspect the block's condition and advise what sized pistons will be needed. This does not change the price, however you ideally will want as much cylinder wall thickness as possible, as that will hold power better, and it will give you room in the future to rebuild again if need be.
We also always use our in house torque plate to properly stress the block as with a head installed
Unlike other builders that order the pistons and drop them in, we make sure each bore correctly matches up with each specific piston! This is done to maximize fitment and sealing, which leads to more power and less blow-by.
Please note this does not include the core charge. We can easily source an engine for you, or you can send yours to us for building. We've built countless engines over the years and shipped them worldwide, including multiple builds making more than 1000 horsepower.
This listing is for a build short block, which does not include, long block assembly, setting the cam timing, installing the heads, setting the valve lash, head studs, valvetrain, etc. We can do a full build including those things as well, just let us know what your goals are and budget is!
Contact us with your address for a shipping quote! Listing does not include shipping price to or from us. We can assist with the logistics and having that taken care of.
Ask us about additional "white glove" service options to really make your built engine stand out!

ACL Lexus V8 1UZFE/2UZFE/3UZFE Standard Size High Performance Rod Bearing Set
Need just the rod bearings? We typically stock these, the main bearings, and thrust washers!
Don't get stuck using those old, used, obsolete hand-me-down Supra injectors, start fresh with a healthy size and don't look back! These drop in to your stock fuel rails!
All Victory injectors start out as Bosch cores. They are then sized and matched within 1-2% providing exceptional idle quality. All injectors come with a limited 2 year warranty (minus 2200cc injectors.) You will also receive 1 free cleaning within the first 2 years! All injectors are a top feed high impedance injector and a direct drop in on the 1uz/2uz/3uz. VVTi engines supported as well. Make sure you select your size from the drop down menu! Includes a full set of 8 for your UZ engine
Please contact us for wiring options. While we try to sell these as drop in, plug in injectors, the plug-n-play adapters may be on backorder. You may have to wire in the 2 wire connectors to your harness yourself, in which case they will be included.
550cc, 650cc, 850cc, and 1000cc use USCAR connectors. 1200cc, 1300cc, and 1650cc use EV1
Power steering pump mount bolts for the pump bracket to the cylinder head. NOT the pump to the bracket.
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
High performance progressively wound PACALOY™ beehive valve spring and high-grade titanium retainer kit. This kit was engineered to match Kelford camshafts for ultimate quality performance and reliability.
80lb seat pressure @ 34.30mm
Installed height / 190lb @ 12mm lift
Coil bind is at 21.0mm
Fits all 1998+ UZ engines, including 1UZ VVTi, 2UZ, and 3UZ! Usually you do a timing service at the same time as replacing this, since it's water pump driven. In any case, we only stick with OEM factory parts. Do it once, do it right. And nobody does it better than Toyota!
Fits all UZ engines 1989-2010! Includes all 8!
The non-VVTi 89-97 engines came from the factory with platinum spark plugs, however you can directly replace them with these iridium long life plugs instead.
One thing Toyota seems to have struggled with for a few decades was valve stem seals. We use these Viton stem seals on all 98+ UZ engines we build! That includes 1UZ VVTi, 2UZ (VVTi and non), and 3UZ engines.
If your engine smokes briefly at startup and at no other time, it's likely time to replace these.
Please make sure you select the correct engine, as the 98+ seals are different from the 89-97 ones
Please note there are 2 different diameter pulleys the UZ engines used. Depending on your setup, you should have either a 90mm or 102mm pulley. We do include a serviceable bearing as well with these pulleys, which will last the life of your engine!
You will need to verify which setup you have before purchasing!
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.
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!
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!
Alright, lets see, who makes these...
What?? Nobody does? Oh, okay, guess we'll have to then!
Available in stainless steel, this pair (both included) are the same dimensions as the factory header flange, used on the SC430 for instance. If you're looking to make a set of headers that bolt up to the factory H or mid piping, this is what you'll need. Or perhaps your exhaust is rusted, and you just need replacement options.
As seen in the pictures, they match perfectly over a factory header, but still give plenty of room for improvement when it comes to flow.
We also make the flange that goes from the manifold to the head! That can be added as well.
Factory exhaust manifold not included. Why would you use one of those anyways? Ew.
Please note this is a different flange shape from the non-VVTi 1UZ, and they are not interchangeable.
Made in the USA!
Finally, a solution for valves that doesnt cost $1200+ to have a custom set made, and 6+ week wait time! We now have a solution for all UZ Toyota V8 engines to run upgraded, stronger valves that fit properly and arent simply repurposed from another engine.
That's right, these are specifically made for your 1UZ, 2UZ, or 3UZ! After many years of trying to have a reliable solution, we now offer these valves for anyone looking to build up their UZ properly and do fun race car/truck stuff with it.
We now offer these as an option for all build engines and heads we do. Do you need them? Well, do you want to second guess not putting them in while the engine was apart getting serviced?
Performance cams for different stages of modified 1UZ VVTi and 3UZ engines with various upgrades. Choose your preference from the dropdown menu option! Despite what you may have read, these cams do NOT work with 2UZ engines.
Do you have a hydrofan you're eliminating? Or a non-serviceable, pressed on (instead of bolted on) center idler? We have an easy fix! Let us know which engine you have and we'll get you the right fitment idler bracket.
Fits 98+ UZ V8 engines! Factory OEM Toyota. Usually ships in a few days.
Fits 98+ UZ V8 engines! OEM part, no cheap knockoff here. Usually ships in about a few days
Brand new original hardware to mount the OEM auto transmission bellhousing to all 1UZ and 3UZ engines, as well as 1GZ V12 Centurys running the 4 speed A342E automatic
The factory cast bracket for the timing belt tensioner could use an upgrade. This becomes especially apparent when running higher lift cams that makes any UZ an interference engine! Our billet 1UZ timing belt tensioner design uses 7170 aluminum with a lubricated press in bushing to hold up to the rigors of high RPM, high lift cams, heavy time and endless mileage. Made in the USA!
Fits all UZ engines, including 1UZ 2UZ and 3UZ
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
Already have a supercharged UZ with an engine pulley kit? Finish up the look and replace that idler pulley with one of ours! XAT is always looking to offer as many Toyota V8 parts as we can, and we will continue to bring more parts to market as long as we are alive! These billet pulleys include a serviceable bearing (not pictured), so the pulley should last the life of the engine.
Fits all UZ engines!! 1UZ, 2UZ, and 3UZ
Display engine is a 2UZ, ready to get blown! This is one of those little important parts included in our full UZ Whipple kit to make it fit right.
Made in the USA!
TEVI-1093D and TIVN-1093D oversized valves by SuperTech for all 98+ UZ engines
This is a full set of Super Tech +1.5mm oversize valves for all VVTi UZ engine heads and all 2UZ heads, both intake and exhaust. For those looking to squeeze the most out of their Toyota/Lexus UZ V8, we have you covered! Please note these do not fit the 1989-1997 1UZ Heads
Features:
☼ The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)
☼ Surface finish is smoother than with chromed stems, having less friction between stem and guide.
☼ Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
☼ Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
☼The nitrided layer is adhered to the base material at a microscopic level, so does not "flake" or brake when the valves bend due to impacts with the pistons.
☼ The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.
☼ All valves are swirl polished, have stem undercut and a hardened tip
Intake:
Head Diam: 36.00mm (+1.5)
Stem Diam: 5.48mm
Length: 95.05mm
Part Number: TIVN-1093D
Exhaust:
Head Diam: 30.50mm (+1.5)
Stem Diam: 5.47mm
Length: 95.10mm
Part Number: TEVI-1093D
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.
Looking to run a big boy Sequoia 150 amp alternator on your JZ, UZ, or GZ? We have the fix to make the connector plug-n-play! We've even used this when replacing the alternator on one of our V12 1GZ GZG50 Toyota Centurys!
Please note the 1GZ uses an 8 rib belt, so when swapping your alternator, you will need to swap the pulley as well. Made in the USA!
Pre89 1UZ and 3UZ fitment confirmed reusing the stock Supra brake booster! Billet mounts for your aluminum UZ engine (or motor mounts, if you're wrong) into the MkIII Supra chassis! The pre89 version is finished and now available. If you have a 1989 model year Supra, please verify the subframe you have (or if your engine mounts were square or round) before ordering. Made in the USA!
Helpful hint: Square mounts came on the earlier cars, round on the later. 1989 was the crossover year, so please verify on your car. You may also need to shave the isolator part of the mount slightly for better fitment between the engine/mount.
Includes rubber isolator mount! Well, not actually rubber, it's UHMW (ultra high molecular weight) with a shore hardness of 68D, roughly equivalent to over 100A (which is a more familiar comparison scale). Despite being one of the smoothest V8s ever created, we prefer having a dampening barrier vs. a "solid" mount to reduce NVH for street cars.
These make bolting in your favorite UZ engine a breeze. Billet aluminum mounts, milled on a 5 axis CNC machine IN THE USA. Only the very best out there!
These are for the non-VVTi 1UZs, VVTi 1UZs, and all 3UZ engines. Please note the 89+ version is different, but we do stock both!
We cannot confirm fitment with the 2UZ. The iron block engines have a different mount location, so the mounts will be different.
These are GUARANTEED* to make your engine faster!
*These covers are absolutely not guaranteed to make your setup faster. Please don't believe this.
Who else but XAT?? We're starting an initial group buy on having all 4 timing cover pieces (both cam gear covers, mid cover, and lower timing cover) made in pure carbon fiber (no fiberglass). Carbon fiber is a known strong, yet lightweight material used on nearly every race car and high end exotic today!
Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement engine bearing, P-Series is suitable for most OE applications. Due to the increased load capacity of the Tri-Metal design, it is a suitable upgrade from Bi-Metal engine bearings.
These V8s arent getting any newer, but they have a ton of life left in them! Keep your UZ on the road and making power with factory OEM replacement parts. We typically keep plenty of these kits in stock!
Kit includes all OEM:
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!!
Please note these typically take 2-4 weeks MINIMUM to ship out
ATEMU simulates most critical features of particular Toyota / Lexus auto transmissions which were available for UZ / JZ equipped vehicles since 1998. This makes it possible to obtain rated power from engine when using factory ECU and any transmission other than that ECU is designed to work with. Factory ECU would otherwise enter limp home mode with significant power and torque loss (for example, VVTi set to max retard for 1998-2000 Lexus LS400) Some non-critical error codes remain intact for simplicity of installation and reducing the cost for off-road application. These codes can be easily addressed with additional components if emission test has to be passed for street legal application.
We now offer the additional resistor pack to wire in if you need to eliminate the check engine light (CEL)
Many users have run into an issue with drive belt routing when installing a supercharger setup onto an engine still utilizing the A/C unit on an SC/Soarer chassis. Elate has developed a bracket that utilizes 2 positions on the engine to securely mount to along with positioning a 60mm idler pulley at the correct offset allowing maximum belt engagement for the supercharger.
Kit includes:
~ Billet machined 6061 aluminum bracket w/ media blasted and anodized finish
~ 2 x 110mm bolts to allow the unit to be mounted to the engine
~ 60mm diameter smooth polymer idler pulley (fitted) OR 60mm diameter 6PK steel idler pulley
** Laser etching may differ from time to time**. Expect a significant wait time of weeks or longer.
Brand new factory OEM Toyota bolts to bolt the bellhousing to your engine!
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!
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.

Superior viscous damper design controls harmful torsional vibration across the entire rpm range. Reduce wear on engine components. Reduce risk of crankshaft failure. Improve timing. Unleash lost torque and horsepower. Precision CNC machined and balanced high-grade steel components. Corrosion resistant black zinc finish with engraved timing marks. No maintenance required. Trusted by leading engine builders worldwide. SFI 18.1 certified. Made in USA.
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!
With plenty of different fitments, these flywheel bolts are most likely the ones you need. These are used to bolt the flywheel to the crankshaft. Includes moly lube! Specific fitment includes but is not limited to:
☼ XAT Racing R150, R151, R154 etc. 1UZ/2UZ/3UZ Manual Transmission Adapter
☼ XAT Racing W55, W58, etc. 1UZ/2UZ/3UZ Manual Transmission Adapter
☼ XAT Racing KA24 / SR20 1UZ/2UZ/3UZ Manual Transmission Adapter
Please note these will NOT work with multi disc clutch kits (such as our QuarterMaster twin disc kits).

These bolts are also meant for the above manual transmission swaps only, not the factory automatic.
High quality precision machined. Made from proprietary Manganese Bronze. All guides need honing after fitment.
Please note the 1UZ non-VVTi fitment is not interchangeable with the 98+ engines
PPE Engineering is one of the longest running header suppliers for the Toyota/Lexus UZ V8 platform, and it's easy to see why! These headers are hand welded on a jig and nicely ported afterwards. These exhaust manifolds are made of 100% 304 stainless steel using a 4-1 design, and feature 1 5/8" runners with smooth formed collector and 2.5" outlet. They are a direct fit to the stock catalytic converters. Power gains are 18-20 whp and 20+ ft lbs!
Please make sure you select the correct car application so we can send the correct header design out for you. Price is for both headers. Please keep in mind these are made to order, so there will be a wait time of at least 3 weeks or more.
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.
To go with your SuperTech UZ valves, you'll want these SuperTech springs as well! Please note these are not for 1989-1997 1UZ heads. They are single valve springs, so they are lighter and get the job done just as well!
☼ Valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high RPM, and better memory.
☼ Computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions.

Once again XAT Racing is filling the gaps in the TOYOTA V8 market with another custom product made exclusively for all 98+ TOYOTA UZ series V8 engines! When building a high horsepower engine, a good focus is on the durability factor of the parts used to complete the engine. The engine's intake and exhaust valves are one of these areas needing to be more robust and/or improved upon when building sustainable power. XAT has one again teamed up with industry giant MANLEY to bring our new 1UZ vvti, 2UZ, 2UZ vvti, and 3UZ Stainless Steel valve kit to market! These valves are available in stock size, .5mm oversized, as well as 1mm oversized. Full stainless steel construction with a swirl polished finish for the best available fitment and performance factor for you, the valued XAT Racing customer.
These valves come in a complete kit of 16 intake and 16 exhaust valves for one engine. Might take 2-3 weeks to make and ship out.
What better option than factory? Instead of paying $400+ for an alternator in a Toyota box, we offer this same OEM alternator for a much more reasonable price. This specific listing is for the 90s style 3 pin oval connector. Please verify that you have this same oval style, and not the round 4 pin of some of the 2003+ UZ engines.
There may be a wait time for an OEM alternator. In the case that they are on backorder, we can likely get an equivalent brand instead. Feel free to contact us for availability first!
Please note depending on your application (including Century) you may need to cut off the extra mounting tab. This tab was added on later engines and serves no purpose on many applications.
For Century GZG50 V12 fitment, you WILL need to reuse your old pulley.
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!
UZ series V8 Stainless Header Flanges (both sides for one engine), fits 1UZ, 2UZ, 3UZ, VVTi or non-VVTi. MADE IN THE USA! If you are making quality headers or turbo manifold the work starts here. Precision cut and zero warp-age during the process. We also offer optional flange thickness. Price is per pair for one complete engine, both flanges. Mild Steel available as well in the drop down menu. Fits all UZ engines: 1UZ, 2UZ, and 3UZ engines, VVTi or non!! Made in the USA!

Please note the 89-97 ones are different from the 98-10 ones
So your old, reliable Toyota truck isnt making much power. Probably less than 200 HP nowadays. But it's as reliable and solid as ever! If only it went a bit faster...
XAT is here to help! We can offer a full turn key swap for your truck, giving it a huge boost in power while still keeping it all Toyota, and all reliable. We will tailor your build to suit your needs, depending on what your goals are for your truck, and what you need out of it. Here's what you can expect from our build process to start with:
Please note we will have NO way of ensuring it will pass any emissions testing. This is for off-road vehicles only. You will need to consult your local laws. You may need further modifications done locally to conform to any local legislature, which will be solely your responsibility. This is also a SERVICE and DOES NOT INCLUDE THE TRUCK. Depending on what is supplied to us, there may be a great deal more work needed to get it to where it needs to be.
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!
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!
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.
Brand new OEM front main seal for all 1989-2010 UZ engines! Typically ships within a day or two!
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!
Select your specific UZ engine application from the dropdown menu!
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.

Please note these will not fit the 1989-1997 1UZ non-VVTi engines. Typically ships within a day or two!
The 98-02 UZ engines also had rubber bolt washers like older Toyota engines did to seal around the bolt holes of the valve covers. These should be considered to be replaced when doing the valve cover gaskets. Double check your engine to see if you need those as well
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.

☼ XAT Racing CD009 Manual Transmission Adapter
Please note these will NOT work with multi disc clutch kits (such as our QuarterMaster twin disc kits). Please reach out to us if you have those applications, as it will depend on which flywheel/clutch setup youre running. These bolts are also meant for the above manual transmission swaps only, not the factory automatic.
Fits our 1UZ 5 speed adapter kits. Rated for 480 ft lbs
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
Replacement friction surface disc for your XAT CD009 swap! Fits both UZ and JZ applications. Does not fit our 7M - CD flywheel
Includes all replacement hardware as well! Specific fitment for our in house flywheel, unlikely to fit other manufacturer flywheels
Includes replaceable friction surface plate, so it is infinitely rebuildable! Made in the USA!
The flywheel itself is 10.5 lbs, and the full weight of clutch and flywheel combination is 25 lbs.
Custom made in house full size flywheel! This flywheel is meant to be an option with a full size ring gear, with extra mass and MOI to make for a more reasonable street driving setup when used with an XAT QuarterMaster 8.5" twin disc clutch
This ONLY is made for the QM 8.5" twin clutch (not 7.25") and is NOT meant for single disc clutches. Made to fit 1UZ, 2UZ, and 3UZ engines with our manual swap conversion parts.

Link continues to gain traction in the UZ Toyota/Lexus V8 market, and rightfully so! They have an excellent selection of options available, and are an XAT favorite when it comes to engine management. Why pay extra for the AEM name when Link is just as (or even more) capable?? From now, on, you can expect all XAT projects to be powered by Link ECUs.
Each harness is custom made to order, so please be patient as you can expect a 1-2 week wait time for manufacturing typically. Please feel free to reach out to us beforehand and let us know what kind of application this is for. Swapping a 1UZ into an S13 or S14 240SX? Putting a 2UZ in a Tacoma/pickup? Factory Crown Majesta or GS430 getting "the beans?" Let us know so we can be sure to have the right harness made for your project.
This is not for a full engine harness, does not include ECU or sensors. This listing is for a plug-n-play adapter to fit your factory harness, whether it remains untouched or is rewired for a swap. Depending on your plans, you may need other parts as well for everything to work properly. If you're boosting it, you'll no doubt want MAP and IAT sensors to go along with it. Although superior up and down, the VVTi engines also have additional considerations over the non-VVTi, and reaching out to us via phone or email (sales@xatracing.com) is the best way for us to get you situated with what you need.
Please reach out to us with any and all questions, as your application may need more consideration or wiring than standard
Fits our 1UZ 5 speed adapter kits. Rated for 398 ft lbs

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!
