The Evo was a better platform for tuning than Subaru. Subaru builds a better car overall. imwo.
I kept my engine mods more conservative - streetable, but about 100 more horsepressure than stock. Probably much for my average autocrossing skills. TD04 with a 19T compressor wheel. 21 psi from 3200 up to 7100 rpm redline. Is not slow.
Swapped out suspension components until I hit a good balance between streetable and the ability to dance. I will never do this to a car again.
I no longer flog it, rarely using the maximum boost.
