boost the F22B1 or 2, my buddy has a boosted F22B2 (non vtec) he's pushing 10lbs of boost and is reliable as NE thing. been running like this for more than a year and he is pushing V8 #s (220HP, 290ish FT LBS TQ) You do the math. im getting the same kit hes got and told me to expect better #s since i have VTEC.
