My uncle and pops both have Z's (kinda funny), but my uncle ran a 13.8 bone stock (2005) Z. My dad has yet to run because he just broke the engine in.Originally Posted by DJSHADOW7
When I read posts on the Z boards of them beating STi's/Wrx's its mostly from a roll.
Forced Induction is what does wonders to the Z. Adding an intake and headers/exhaust, really wont net too much.
