Aussie Mike,

I am not claiming to be and expert or anything but my advice would be not to wast you time.

I have been in and out of the Toyota Supra tranny amongs other things and they are truely reliable. How ever they are delicate in the same manner. I had a supra done up with a 60-1 turbo running 20 psi boost , with a Haltech E6 programmer , amongs cams and other things. I would estimate my car putting out about 450 + hp others claim it was putting out more which why I am siding on the low side with out dyno results.

The tranny held up after a rebuild and when I was rebuilding it there was no aftermarket parts except those from the dealer. So it was expected to break again. This was a street car so it did not see abuse compared to a track car.

When I bolted the slicks on I worried about the tranny, which not too many times.

Also, the 7M motor generates low torque at low RPM this maybe an issue with having a LS1 motor.

Also, the 7M torque comes in gradual compared to a NA motor.

Best of luck
