i thought the purpose of the 6 speed in the rx-8 was due to the 4.30 rear?

 

My ideal transmission would be a rebuilt one in my car with a smaller, taller, whatever 5th gear. I'd like to keep my RPMs a little lower when cruising. That's it.

 

To anyone not sure about what power the FE tranny will take, chew on this. The UK's fastest FB is using a standard FE box, running a 10.91@130mph. It runs a 12a engine, with a HKS T51kai running 25psi and revving out to 12000rpm. A crude car, but effective.
