XAT Racing 1GZ V12 to R154 5 speed Toyota Transmission Adapter Plate

This is an adapter plate to attach a Toyota R Series 5 Speed manual transmission to the 1GZ Toyota V12 powerhouse! Fully CNC Machined in the USA from 1 3/4" thick billet 6061-T6510 aircraft grade aluminum plate.

Please inquire if you have a chassis with a popular swap, as we are likely able to provide the clutch line. You will also need a clutch/flywheel combo, the GZ 4 speed auto bellhousing, and whichever other parts your chassis requires to make it all work. together Please contact us with your project details so we can set you up with the right parts you need!

As a quick recap: You will need the 1GZ V12 automatic bellhousing with this kit. The 6 speed auto from the 2005-2017 cars will not work. You can use our "OEM style" or 11 lb chromoly flywheel with these kits if you plan to use a single disc clutch. Single disc clutches will need to be an SW20 MR-2 turbo. We have all sorts of available clutches, many in stock, at the bottom of the listing.

Which version will I need?
All R154 transmissions should have the long shaft. R150 and R151 transmissions from 1996 and newer trucks should also have the long shaft, however we have seen newer R155s from the 2nd gen Tacoma, Hilux, Prado, etc. using a short shaft. We insist you measure your transmission before placing the order.

95 and earlier truck transmissions should have the short shaft. Again, we recommend double checking yours before ordering to avoid any confusion or mixup to avoid any restocking fees.

The longer shaft length is 7.25" from shaft to the case of the transmission itself (with the bearing retainer off). The shorter shaft version is about 30mm shorter, or roughly 6"

What this kit comes with:
☼ XAT Racing UZ R Series Adapter Plate
☼ Hardware needed to install plate
☼ Throw out bearing with fittings (optional, but required)

You will also need:
☼ Our flywheel: you can NOT use the R series I6 or V6 flywheel with our kit. This will not fit the GZ engines. We have 3 separate flywheels that fit: OEM style budget and lightweight quick response. Check out the related parts on this listing.
☼ GZ factory automatic bellhousing (6 speed bellhousing will not fit)
☼ R series transmission (R150, R151, R154, and potentially MA-5/AR5 GM transmissions)
☼ Clutch/pressure plate: this will depend on planned HP goals and chassis usage as well as personal preference. We have a myriad of choices and brands available, many in stock
☼ Clutch lines: Clutch line will depend on your chassis (LHD, RHD, or if it's a swap). We can provide a line as an optional extra if we you can provide the length and fittings needed.

You may also need other manual conversion parts, depending on your chassis. Please keep in mind you WILL need to use a 3/4" bore master cylinder with this kit. The factory master cylinder may be enough, however it will ultimately depend on your application. The majority of Toyota car manuals have a 5/8" bore master. The optional master cylinder we provide may require further chassis modification to bolt up to your firewall.


BENEFITS OF XAT RACING KITS OVER COMPETITION

☼ We don't use aluminum ring gears. I can't think of a single OEM that has used an aluminum ring gear in a production car before. For long term reliability, we use actual OEM hardened steel ring gears on our flywheels
☼ No starter/plate shimming. Our plates are all billet CNC'd, so each one is exactly the right length. No guessing and fumbling, just correct, proven, and tested fitment.
☼ Starter bolts do not need to be shortened or clearanced in any way
☼ We've been selling our kits for over a decade and invested heavily in support and upgrades for these underrated engines
☼ Solid customer service before, during, and after purchase.
☼ We don't use "proprietary" clutch/flywheel replacement parts. Guess what...neither does our competition! They will tell you that to make sure you keep coming back though.
☼ We run XAT Racing full time. This isn't just a side hustle for us, it's our passion!
☼ Quality, OEM parts used where possible. We avoid using inexpensive garbage just to get a sale and maximize profit. ☼ Every individual part and fitting is specifically chosen to be proven and solidly reliable.


Bleeder Kit Options:

We also offer a bleeder line kit to make life much easier, instead of being stuck with having the bleeder fitting inside the bellhousing. This includes the fittings needed for a -4 AN setup to convert to. In most cases, the 10" line will be enough, but opting for something like the 36" line will give you the freedom of running the line anywhere. Anyone who has done the hydraulic bleeding process for brakes or clutch line on their back on the ground will agree that having it mounted in the engine bay instead with a quick twist makes life much easier!

Clutch Hydraulic (Feed) Line:

Typically, the clutch hose for most applications should be 36" in total length (3 feet, about 1 yard/1 meter roughly). We can supply custom hoses with custom lengths as well, but for the majority of applications, 36" fits fine. The one we use with almost all builds has a 90* fitting on one end (to bolt to the banjo bolt fitting from this kit), and the other a straight fitting. Please contact us if you have a specific length you're looking for. We try to stock a variety of options for our customers, but keep in mind that some custom setups may require a bit extra time to ship.

The banjo bolt we use is M10 x 1.0 for most popular Japanese applications, including most Toyotas and Nissans.
