apexi n1 with 2.5
he's thinking about 160 to the wheels. im thinking more around 130-35 ish.
the dh-racing manifold GUARANTIES 25 to the wheels so he just intrested.
lol btw its a 99 gsr
I'm going to have to doubt 25rwhp gain. Not saying it's impossible, but unlikely. A lot of times, companies will say about 25-20 rwhp gains for an exhaust header but what the common person doesn't take into account is the extent to which the car was modified (ie. forced induction). On a motor with forced induction, those numbers aren't that hard to believe. I'll agree with you on mid 130's.
