GR700 T56 Magnum 6-speed swap kit for the Mazda FD3S RX-7

You might have seen videos of my 2JZ swapped FD3S... But this will be the first time you will see it since I did the GR700 transmission kit swap.

I have heard people saying these magnums shift clunky, and that the T56 cannot handle RPM. I made this video specifically for those people. I shift my RX7 at around 8k with no issues, and I shift my white Supra at north of 10,000RPM. So anyone that says these cannot handle RPM does not know what they are talking about. With a properly setup clutch these transmissions shift flawlessly. Also, as you can see in this video the transmission shifts super smooth, with very short throws. I think my RX7 shifts better now than it ever did with the V160! The throw is 1/3 the length, and it engages very easily even at high rpm.

The GR700 for the FD3s is a new product I created and is available to anyone with a 2JZ swapped FD3S Rx7, specifically setup for the tech2 subframe. I can also work with other subframes if you can provide dimensions.

About my car:

I am using a Tech2 subframe to mount the 2JZ, and the motor itself is a mild build. I am running a "budget" motor which is shelf Eagle rods and JE pistons, stock crank, and an unported head with HKS 272 cams. The rear is a Samberg 8.8 IRS with 4.30 gearing.

The car makes around 650whp on pump gas at 18psi, and about 740whp on E85 at 26psi. I have always ran a V160 in this car, but with parts becoming scarce I wanted to sell it before I had any sort of issue with it. The logical choice was to swap it to one of my GR700 T56 Magnum kits. These trans have tons of aftermarket support, a super strong gearset, and can handle RPM well.

The car has gone 9.6 in the quarter mile and trapped a best of 153. It is a fun all around street car. No cage, no rollbar. I am excited to take it back to the track and see what it will do with the GR700 in the car.
