RX-7 Manual Transmission Project
 

Howdy all, new member here with a few questions concerning the capabilities of the manual boxes found in the RX-7 (the Turbo II is what I'm told I should be looking for).

While I don't own an RX of any flavor, I'm desiring to mate a manual transmission to my V8 Mercedes. I've long desired a manual in that car, but sourcing the bits and pieces AMG used (Getrag 265, plus a bellhosing design to bolt it right up to the M117 [which someone I know has the plans for, but won't share because he wants to generate profit for his business, understandably so, I guess]) is time-consuming scouring the planet for that stuff. I don't expect this to be a weekend project, but I do want to get it done in a reasonable amount of time with minimal downtime on the car.

Other options include Supra transmissions (outrageously expensive, along with a T56 or anything like that), as well as the T5 which tops out right where that European-spec V8 runs (228HP/299lb-ft). North American motors were hamstrung by reduced compression ratios and a more restrictive top end.

At any rate, someone suggested the transmission out of an RX-7 Turbo II. My questions are as follows:

1) How much torque can these boxes handle?
2) How much will one run me?
3) Assuming rebuild kits are available, are there also kits offering stronger internals?

Thanks!

Found the answers I was looking for. Thanks!
