Introducing the GR1000S kits. PPG Sequential T56 Magnum - Bolt in kits for the Supra, IS300, SC300, and RX7

Grannas Racing GR1000S Sequential T56 Magnum kit

Want the ultimate swap kit for drag, half mile, road course and still use your car for limited street use? Then look no further than the GR1000S sequential t56 magnum kit

Using the strong Tremec T56 magnum case, and stuffing it with the strongest PPG 6-speed gear set imaginable, then combining it will true full power no-lift sequential shifting makes this the ultimate 6-speed setup. This transmission has been proven durable, and there are vipers making north of 1600HP and well over 1400 wheel torque with this setup.

The PPG shifter shown is included, and can be located for multiple vehicles depending on your needs. In these pictures, you will notice the included shifter can be relocated rearward to allow perfect fitment in the MKIV Supra, Lexus SC300 or Lexus IS300, and Mazda RX7 (FD3S). We can also move the shifter to fit your chassis, just let us know what car and I will get it setup.


The GR1000-Sequential kit uses a T56 Magnum case with a full billet PPG gearset, which is available in multiple ratios to best suite your cars needs. Including a new ratio that matches the V160 gearing almost identically. So if your looking to do the baddest 1/2 mile Supra then this is the transmission you need.
