Lexus 1UR-FE 2007+ 4.6 V8

We at XAT are not thrilled with the lack of Toyota/Lexus UR engine support, so we've purchased a few spare engines for test fitment and are developing new parts for this market! One of the obvious go-to for race builds and anything making higher HP is a set of ARP head studs. ARP says they are working on a kit, but who knows when they will be available, and at what price. Perfect for any build from stock to 1000+ HP

Meanwhile, we have a set of our own ARP2000 offerings that we have confirmed to fit perfectly! Regardless of if you're building a high HP N/A engine, a boosted setup, or even just a factory rebuild, you can't go wrong with ARP hardware!

Fits all UR engines, including the following:

• 1UR-FE (2010-2021 4.6 in the Tundra, Sequoia, GX460, and overseas Land Cruiser 4.6)
• 1UR-FSE (2008-2010 GS460, 2007-2017 LS460, and Crown Majesta 4.6)
• 2UR-FSE (2007-2017 LS600h)
• 2UR-GSE (2007-2017 IS-F, 2015+ GS-F, 2014+ RC-F, and 2017+ LC500. Does not include LC500h)
• 3UR-FE (2007-2021 Tundra, Sequoia, LX570, and Land Cruiser 5.7)
• 3UR-FBE (same as above, but for flex fuel vehicles)

These are not simply overpriced regrinds of stock cams. There are machined from new billet cores, with a profile made specifically for super charged engines! Whether you're using a TRD/Maggy blower or stepping up to the Whipple, these cams will help make the most of your "big block Toyota" project.

These cams will be for anyone looking to get the most out of their Tundra, Sequoia, LX570, GX460, Land Cruiser, etc. with the 3URFE engine. THESE DO NOT HAVE THE LOBE FOR THE AIR PUMP FOR 1UR-FE ENGINES. OTHERWISE THEY WILL FIT.  We have specific 1ur-FSE camshafts as well- please inquire.

If you've already done basic mods like intake, exhaust, and tune, this is the logical next step for you to have some noticeable gains, however you can expect to need at least an upgraded valvetrain to run these. We cannot confirm fitment with the LS460 and GS460 car 1UR-FSE engines.

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.

Pictured is one set from the actual run of UR cams made!! We have just a few sets left in stock, as these are low production numbers. Once they leave, there may be a few weeks wait time before we get more in.

Cam specs for factory cams:
236 duration, 6.36mm cam lift intake
235 duration, 6.26mm cam lift exhaust

Cam specs for XAT SUPERCHARGED cams:
247 duration, 6.86 cam lift intake, 209 duration at .050"
248 duration, 6.85 cam lift exhaust, 209 duration at .050"

With the factory rocker ratio, that's 10.76mm of valve lift with our cams! As such, you should verify clearance with your pistons and these cams. In most cases, you may need custom pistons.

In the interest of ever expanding our knowledge base, we are offering actual bench flow testing numbers for various Toyota heads, free! Included are actual numbers from heads we have ported in the past for actual customers.

Although it looks cool to have big, polished, shiny intake and exhaust ports to show off...in the real world, this is impractical. Aggressive port jobs work for a dedicated drag race car or circle track roundy-round car that will always be going wide open throttle, pushing well over double the HP of the factory setup with big cams and/or extra boost from a turbo or supercharger. Anything else getting this treatment would end up losing low and mid range power as charge air velocity drops, and a little turbulence is conducive to better air/fuel mixing.

With decades of hands on experience, our guys hand port every head that gets our pocket port service. We have the know how with where it is needed most, and how much is needed. Our results show modest improvements throughout the RPM range, and noticeable gains in the top end, without sacrificing much low end power to get there.

Some engines (such as the 1URFE and 3URFE, which share the same exact cylinder head) already have massive ports that have been expertly engineered by Toyota. Are there gains to be had from porting these heads as well? At the very top end above 6000 RPM, yes, potentially, with enough cam and enough boost. For the vast majority of users making high HP N/A or even mild boost, there's not much benefit from doing so. As you can see from the numbers above, the stock UR V8 head already overwhelmingly outflows even a ported 2JZGTE head! This makes this 2nd generation of V8s a terrific starting platform as a capable powerplant.

Please keep in mind these are made to order nowadays and will have a 3+ month wait time. The OEM head gaskets are more readily available. These are for stock bore/liners only, not for Darton sleeved blocks

Both sides are included!

Material: MLS
Compressed Thickness: .034

Overview

This world exclusive Bullet designed kit is perfect for the Landcruiser owner who tows or uses their vehicle for off road workouts. The Positive displacement Supercharger system has been developed with reliability being the main focus. Small boost levels of only 5 psi allow the engine to comfortably perform without stressing internal components, whilst delivering exceptional power and torque increases. The Supercharger delivers maximum boost from “off idle” all the way to the engine redline. This means that instantaneous Torque is available down low where you need it – when taking off from a standing start with a heavy load or caravan on the back or when in low range on a sandy beach or in the boggy mud.

Fuel Economy remains the same (if not slightly better) on average due to the increased torque available from the engine, with returns of under 18 litres per 100kms easily achievable when towing. More power is developed down lower in the engine rev range meaning the engine does not have to rev as hard to produce the same level of power. This is most noticeable when towing up a hill – the gearbox does not have to downshift as often as more torque is available through the mid range.

EGR cooler will also have to be removed with this kit

When we first began to modify and tune the mighty TOYOTA 3UR 5.7L v8 engine we dug into the areas that we could improve the performance and reliability of the engine. We all know that production equipment is made to work within stock performance parameters - so we knew that the fuel system would be the first place we would need to address. While the stock 3UR fuel rails do work just fine- when you start adding HP with a Supercharger or Turbo the fuel demand starts to exceed the flow capabilities of the stock fuel rails. Stock fuel rails are made from pressed and welded steel that have bent crossover and feed ports- these ports are as narrow as 5mm!! To put this measurement into perspective- each injector has a 6mm port on each rail- MEANING the feed port for all 4 injectors on each rail is smaller than just one of the injectors feed ports- WOW - so this is why Tundras approaching 600WHP start to run lean and drop pistons and start welding rings and breaking ring lands- the engine is going seriously lean under these high load situations-  this is where we stepped in- 

XAT Racing 3UR billet -8AN fuel rails are made from genuine RMR fuel rail stock- machined to perfection  in a multi phase manufacturing process. We designed our fuel rail kit to exceed the performance of the stock rails when needed most- so we started with -8AN fuel rail stock- feed and drain ports are all -8AN ORB meaning you get a perfect o-ring seal on all inlets and outlets. Our injector standoffs have locating tabs so your injectors are facing the correct direction as TOYOTA designed- meaning your injector spray pattern is optimized- and not spraying in the wrong direction- this design feature is exclusive to the XAT Racing 3UR billet fuel rail kit. Injector standoffs have 14% larger (7.15mm) feed ports at the injector vs stock(6mm), while the rail inlet and outlet ports are a whopping 82% larger (9.15mm) than stock (5mm).  All standoffs as well as inlet and outlet ports are e-85 safe o-ring sealed for a leak free design- this also means an easy replacement of o-rings if you ever need to refresh the setup. Mounting tabs are located in the same OEM locations and even use the OEM poly spacer and bolt for install- making install as easy as it can get. 

XAT Racing 3UR billet fuel rail kit is offered in Anodized finishes as well if your looking to change up the color or look of the fuel rail setup- 

Each kit comes with both fuel rails with all inlet and outlet ports in -8AN pre-installed as well as all standoffs installed. 

XAT custom in house, made in the USA, billet aluminum fuel rails! Fits all 2007-2021 3URFE engines, including Tundra, Sequoia, Land Cruiser, and LX570. Also fits 1URFE truck engines (GX460, etc.) Made in the USA!
