Full bolt in 6-speed (T56 Magnum) swap kit for 2JZ swapped MK2 Supras. You can choose the transmission of choice GR700, GR900, or GR1000. This kit includes a brand new Tremec T56 Magnum built to spec, Quicktime SFI Steel bell housing, billet shifter relocation, and chromoly transmission mount. Driveshaft and clutch is optional, but recommended to make this an easy bolt-in experience. There is NO CORE charge.

If you add up the cost on all these parts, you will see that I am matching prices with big name speed shops like Summit and Jegs. Not only do I match big box store pricing but I put it all together in a one-stop-shop package deal and also provide you with the little details they don't... like proper hardware and a pilot bearing for the bellhousing, which quicktime doesn't include... Also I trim the bell to fit perfectly, I am not just drop shipping an item and taking my cut of profit like these big name stores. I also include a wiring pigtail kit to make wiring quick and easy. Oh, and did I mention I have actual product support as well? Try calling Summit and asking for help on your T56 Magnum swap!

The stock tremec is rated at 700 ft lbs of torque. Just for comparison, the Getrag V160 is only rated around 500 ft lbs in stock form. These transmissions are STOUT.

I built and tested this kit to be a direct replacement for the Getrag V160. We all know the V160 is a great transmission, but V160 parts have become impossible to find. Rather than risk breaking your transmission and not being able to repair it, I suggest swapping to this setup and put your V160 away for safe keeping. The getrag v160 will continue to gain value as parts become even more scarce.

These transmissions have great aftermarket support, aftermarket gearsets, and parts readily available for when you ruin a synchro or break a gear tooth. 

This is perfectly setup for a 1981-1985 Toyota Supra MK2 (Mark II). The shifter sits perfectly in the factory location.

This bolt-in kit includes:

    • Brand new "stock" T56 Magnum Transmission
    • Quicktime Bellhousing for the 2JZ
    • Hardware for the bellhousing to block and bellhousing to transmission (not included from Quicktime!)
    • Pilot bearing (2JZ crank to T56 magnum) also not included from Quicktime!
    • Full chromoly transmission mount
    • Factory shifter rotated 180degrees puts the shift point forward a bit and places shift point perfectly in tunnel. SEE PIC!
    • Includes wiring pigtail and plug kit
    • Current clutch options are here
      • I recommend the "close ratio" TUET11009 - 2.66, 1.78, 1.30, 1.00, .80, .63 but i can also get this in "wide ratio" TUET16885 - 2.97, 2.10, 1.46, 1.00, .80, .63
      • Driveshafts are available in aluminum and carbon fiber for stock rear diff 

    All transmission builds are created from brand new stock T56 Magnums, NO USED transmissions EVER. These are then built to your specs. Choose the power level you need. 

    This is a brand new T56 Magnum direct from the Tremec factory, and I match the big box store prices. You can buy from me and get real experience or try calling the big name stores with your swap tech questions and see what kind of service you get! Read more here: GR700 Transmission

    We take a brand new Magnum Trans and give it a 1st thru 4th carbon fiber blocker ring upgrade. Upgraded bronze Fork Pads on all forks. Includes sprayer bung mods which is normally a $150 add-on. This is basically a GR1000 without the cryogenic treatment and rem polishing. Read more here: GR900 Tranmission

    We take a brand new Magnum Trans and give it a full REM polishing and Cryogenic treatment of the gear set. We do a 1st thru 4th carbon fiber blocker ring upgrade. Then include upgraded bronze Fork Pads on all forks. Also includes sprayer bung mod and case mods to fit Supra tunnel. Read more here: GR1000 Transmission

    We take a brand new Magnum Trans and faceplated the 1-4 gears. Includes custom billet shift forks, bronze fork pads, and then we do a cryogenic treatment of the gearset, and then do a rem polishing of the gearset. Read more here: GR1000F Transmission  


    Slight clearance mods to the center case are needed to allow fitment into the MK2 supra tunnel, this is included on all my transmissions except the GR700. 

    I recommend a 4.00 or shorter gear to make the car similar to the overall gearing of a V160 car. More info on gear ratios can be found on this page I created T56 Magnum vs V160.


    These transmission's will work well with the factory rear. A carbon fiber driveshaft can lessen the abuse on all driveline parts, and will absorb some of the harshness of the manual transmission.

    The MK2 requires very minor hammering in the tunnel in some tight spots. It will only take about 10 minutes of work to get the clearances in check. I will provide instructions to customers.

    Big thank you to Dan Dulac for helping on the development of this kit! This kit is only intended to work with 2JZ motor mounts built to Wilbo specs. If you have other mounts the crossmember bolt locations may vary slightly.
