I have a 2000 Impreza 2.2l and I am lookin to keep it N/a. I have an intake and am soon to get a dual exhaust for it. However, I am looking to get the most out of it possible. With lets just say Headers, exhaust, Weapon R intake, and a PP6, what should I be looking at for hp? I was aiming for somewhere between 200-250, am I correct in thinking so? Or am I way off? Thanks!

 

Yea you won't be making 200-250 with bolt-ons for a 2.2L NA. Better ask Rallitek what you'd expect with that ecu upgrade, hopefully they have tested your make/model already.
