Full bolt in T56 Magnum-F swap kit for the MKIV Supra. This kit includes a brand new Tremec T56 Magnum-F (built to your choice. GR700-GR1000-GR1000F), Quicktime SFI Steel bell housing, Grannas offset shifter, and chromoly transmission mount, wiring pigtail kit, and hardware. Driveshaft and clutch is optional, but recommended to make this an easy bolt-in experience. There is NO CORE charge for our transmission kits.
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 for EVERYTHING, trimmed transmission case... Also I trim the transmission case 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 the wiring side of things easy. Oh, and did I mention I have actual product support as well? Try calling Summit and asking for help on your import project LOL!
The stock tremec Magnum-F is rated at 700 ft lbs of torque. Just for comparison, the Getrag is only rated around 500 ft lbs in stock form. These T56 Magnum transmissions are STOUT and will outlast a V160 at high power levels. Everything I build is tested rigorously in my racing program. No one else pushes these parts to the level I do! You can rest assured all parts go through my quality control and abused to test the limits of these 6-speed transmissions!
In 2016, I built and tested the first Supra T56 Magnum kit in my own car 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 transmission will continue to gain value as parts become even more scarce, but repair costs will also climb with the decreased parts availability.
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 1993-1998 Toyota Supra. The shifter sits perfectly in the factory location.
This bolt-in kit includes:
All transmission builds are created from brand new TREMEC T56 Magnum-F's, NO USED transmissions EVER. These are then built to your specs. Choose the power level you need.

The OEM MKIV Supra MANUAL tunnel does not require any tunnel modification other than 2 minutes to slightly tap upward at the front side of the oem shifter hole location and also slight tapping back by the shifter area where the reverse lockout solenoid is located. If you are an automatic car it will require some cutting and use of the Tunnel Cover product I sell.
The Magnum transmission gearing is quite a bit different than the factory V160, therefore the factory 6speed rear gearing will be too high (3.13). The NA gearing is perfect, but it may not hold up to higher power levels. The best and easiest solution is to use the OEM 200mm rear which is 3.76, 4.08 or 4.27. All three of these ratios work well with the Magnum swap. The 4.08 would put you pretty close to an exact match to the V160 gearing. The other option is to swap to a Ford 8.8" kit, or Ford 9" Kit. More info on gear ratios can be found on this page I created T56 Magnum vs V160. The absolute best rear ratio is 4.10 which makes this transmissions gearing identically match the V160 gearing.
