well, depending on the boost level. my car is not dynoed yet. a 40-50HP gain is expected on 5.5 psi boost on the GReddy kit. the problem is, the safest recommended maximum boost on d16 with STOCK internals is 8 psi. over it will be risky.......i know a guy who ran 14 psi on stock internals. it lasted a year and the car was being raced on the track almost constantly. it ran low 12's. i do NOT recommend above 8 tho.....
