XAT Built Engines

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

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

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

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

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

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

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

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

Shipping is not included, you will need to reach out to us with your location and we can get shipping quotes to your address! Ask us about additional "white glove" service options to really make your built engine stand out!

XAT 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.

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

We also know the importance of being able to customize your build and have the flexibility to run exactly what your budget allows.

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

• Forged aftermarket connecting rods (BC, Manley)
• ACL rod, main bearings; OEM thrust washer
• New OEM oil pump (XAT upgrade optional)
• Block honing with torque plate
• Hot tank/vapor blast block

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

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

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

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

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

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

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

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

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

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

Standard short block build includes:

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

We also offer upgrades over the above parts!

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

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

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

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

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

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