P & IH & TB porting - ZR-1 Net Registry Forums

Polo-1 · 04-12-2008

On my 92 Z , went from 325rwhp to 396rwhp. 100% stock to ported with headers and corsa (no head work). Night and Day difference. The power never dropped, it was still pulling at the rpm limiter. I think every Z should have this done (top end port work). They are so far off stock, and it makes the motor just pull to redline.

DO IT
