But if I run like 18ish.. would a fmic help at all? I want one but I dont wanna get it just for the looks.. also, can you get around the secondary air injection pump or do you always have to remove it?

I remember reading somewhere that with the turbo ripped out, the 1.8T was aprox 95HP so every 14.7PSI will double that. I have raced my friends stock STi and it is a bit faster, but not much. Im running 19psi, but have other mods too.
Remember the 300hp is what the manufacturer is rating the STi motor at the crank with NO accessories, its probably closer to 285-290 at the crank with all the drive belts added on, a/c compressor/alternator/power stering, etc.. then knock off the powertrain loss and you really only need about 250 at the wheels to be on par with an STi. They are almost the same weight too.
Also dont forget sti is 6 speed for track racing, 6 speed doesnt help for straight line races, thats why the evo was a 5 speed, its less shifts =more time in gear.

The base hp of the NA 20v is 110 or 120hp. It runs basically the same motor but with cams suited for NA. Think compression may be 10:1.
