been searching the gearboxes for a couple of days,

 

the price of a 6spd TT is a lot higher than than the Auto TT.

 

 

are there many complaints or many people happy with the R154 or W58 box? i know the R154 is better than the W58,

 

 

on a basic stage 1/BPU supra

You will get mixed reviews about using the W58 with a TT engine, I was using one with a T61 single at 1.2bar with no issues....whilst others have reported failure on BPU TT.

 

I dont know if failure is down to driving style or just luck of the draw.

If you do no drag type starts and are sympathetic you may get awau with one for a while, but you are pushing it way over its designed torque handling level. Drag starts and brutal, snatched changes are going to be cruel to any transmission, let alone one that's overwhelmed by the engine in front of it.
