hey i got a v4 sti and hav just upgraded to a twisted gt2876r setup i hav full fuelling setup with 800cc injectors walbro fuel pump split fuel rails etc. front mount extractors bla bla bla. just wanna know if someone has run a setup similar to this and how much boost were they running, this is a stock sti engine the internals hav not been forged. i was thinking around 20-22psi???
Same turbo and injector set-up that I have. I am currently running it at 20psi... I have got a built engine now, but I did run this turbo on my standard engine at 15psi and it survived fine (did quite a few track days etc on it like that).

6 speeds (and 5 speeds with TY754XXXXX - from 98-00 models) have 8 bolt bell housings and the others have 4. They still bolt up fine, you just dont use all the holes.
As for the gearbox mounts - they look identical, and will (and do) work. Maybe the 6 speed mount is a bit tougher though due to the extra weight of the box? (a subaru techy person could probably answer that for you).
The 5 speed gearbox subrame is also identical to the 6 speed, so everything bolts straight into a GC or Legacy.
