what bhp are the above items good for? was thinking of 350-370bhp?

 

Gearbox yes, depending on how you drive and intercooler not a cat in hell's chance!!

Agree with Banny.
The box will tolerate a torque of about 370 lbft if driven 'well'.
Powershift it and expect the worst, a blown box and a bill for a 6 speeder!

The TMIC will never hold 350+ for long, it will get too hot too soon and tail off.
Best bite the bullet and do what most do in the end, fit the FMIC which is a leap forward.

for the sti 5 gearbox do I need the rear diff too? I have a 93wrx wagon.

 

If you decide to go front mount you may find this useful all the info you may need from fitting dv adapters mikalor upgrade clamps and problems you may come across follow the links on the group buy page I'm running the group buy and should be due in at the end of the month

Your going to need to upgrade your turbo also as it runs a TD04.
Are you aiming for 350bhp or just going with what your car can do now?

The Sti V5 box is a 4:444 diff ratio and i think yours is a 4:111
4:444 rear diffs can be tricky to find.
