The GR700A kit is the newest version of the full bolt in T56 Magnum XL (long tailshaft) swap kit for the 13B or 20B Rotary powered FD3S RX-7's. The A in GR700A stands for Aluminum bellhousing, as this kit comes with the Grannas Racing cast aluminum bellhousing. This bell is superior for a street car as it dampens noise as well as does not need indexed, it is a direct bolt on bell. The bell will fit both auto and manual rear plate rotary engines.

This kit includes a brand new Tremec T56 Magnum XL, GR cast aluminum bell housing, Grannas Racing billet offset Magnum-F shifter with GR 4" billet shift lever, chromoly transmission mount, bluetooth wiring harness, and all hardware required. Driveshafts and clutches are optional, but recommended to make this an easy bolt-in experience. There is NO CORE charge for our transmission kits.

The wiring harness we include makes for a super clean and simple install. But not only that, but it has a bluetooth module with you can play with the settings such as reverse lockout control, and convert and adjust the T56 speed signal to make the factory speedometer work perfectly. No more need to cut down the reverse lockout spring or wire in a manual reverse unlock switch, this will auto unlock reverse under a set MPH (defaults to 4mph)! All of the settings are all adjustable through your smart phone with an app.

The stock tremec Magnum XL is rated at 700 ft lbs of torque. These T56 Magnum transmissions are FREAKISHLY strong and will outlast all other street transmissions 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. Since then we have developed more and more kits tailored mostly to the import crowd.

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 1993-1995 Mazda RX7. The shifter sits perfectly in the factory location (does require a bit of trimming at the front of the tunnel hole for shifter clearance.

This bolt-in kit includes:

• Grannas Racing Aluminum Bellhousing
• Remanufactured Starter
• Grannas Racing 1.5" offset shifter (If you do not buy the trans from us, you will need to send the shifter to us for modification/changeover)
• Grannas Racing 4" billet shift lever
• Machining of the T56 case to fit starter (ONLY IF BUYING THE TRANS FROM US WITH THE KIT)
• Full chromoly transmission crossmember 
  
• Grannas Racing Rubber T56 transmission mount + hardware
• Includes bluetooth wiring harness
• Current clutch options are here
• I recommend the "close ratio" TUET18131 - 2.66, 1.78, 1.30, 1.00, .80, .63 but i can also get this in "wide ratio" TUET18132- 2.97, 2.10, 1.46, 1.00, .74, .50
• Driveshafts are available in aluminum and carbon fiber for almost any rear end combination.

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

PLEASE NOTE: The T56 Magnum transmission works great with the factory FD3S rear gear ratios. For bigger power cars I recommend a 8.8" rear with 4.10 or a 9" rear with 4.11 gears. You may want shorter gearing depending on your power level and tire size.
