> 310whp is quite loftey as is 360wtq there crazy. Remember you have mostly an oem exhaust still and didnt travis have afully build sti block to make that much? My guess would be 260whp on the same amount of boost your running now. But as pete says im not going to crack an egg thats unhatched.

the fp green was MADE to run at 18-23psi on pump… and LOVES racegas.

the ej20 motors will outrev the ej257 thus giving it a “happier” powerband as well… with a PROPER tune on 93pump i can see 335hp/325tq… on cam2/c16 400/400 easy. with a more useable powerband with the 5spd… assuming it doesnt strip the teeth off 3rd gear.
