The Grannas Racing GR1000S Sequential Magnum Kit is available for all of the chassis I make GR-Series magnum kits. It can also be adapted to any other Rotary or 2JZ powered car. The kit includes SFI-spec steel bellhousing, Tremec T56 Magnum with Sequential PPG Gearset, shifter, transmission crossmember, polyurethane transmission mount, all hardware, and a pigtail kit to make wiring it into your car a simple job.
A sequentially shifted T56 Magnum is truly the best of the best. For quarter and half mile racing this is what you need for lightning fast shifts without dropping out of power. You can full throttle upshift this transmission with lightning speed.
The transmission is based off the Tremec T56 Magnum, and uses the T56 magnum case but is stuffed with a full replacement PPG gearset. This has been tested in vipers making more than 1200 rwtq, so it is incredibly strong. Custom gear ratios are also available at an additional cost, but with the wide range of gear options below most can work with one of the shelf gearsets.
This can be combined with a Quicktime bellhousing, and clutch to make a full chassis-specific kit. I can put together a full front to back kit to make this a bolt in for your MKIV Supra, Lexus IS300, or Lexus SC300. This will require some tunnel modifications to the shifter area. Contact us for more information.
This setup includes shifter shown in the pictures, and we can move this shifter forward or backwards in whatever location you car requires. All we need are some simple measurements. We can also help you determine the best gear ratio for your setup as well.
