Full bolt in T56 Magnum swap kit for the 1993+ Mazda RX7 using the Tech2 subframe. This kit includes a brand new Tremec T56 Magnum (built to your choice. GR700-GR900-GR1000-GR1000F), 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... I also include a wiring pigtail kit, and billet speed sensor block off. 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 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.
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 1993+ Mazda RX7 who swapped to 2JZ using the Tech2 subframe kit. The shifter sits perfectly in the factory location.
This bolt-in kit includes:
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.

I recommend a 4.10 gear to match up well to the close ratio magnum gearing. More info on gear ratios can be found on this page I created T56 Magnum vs V160.
