well this month i have been busy. my cx went from being bone stock to having some sack. i first put in a p07 head (thought it was a z6 head), z6 intake manifold, p08 ecu, and short ram intake. then 2 weeks later (last week) i put in a z6 head witch started to knock like a bitch. i tore off the whole rocker arm assembly and cleaned everything out and that fixed the noise. z6 distributor was leaking oil like a bitch. so i pulled the cx one apart and robbed a shaft oil seal and put it in the z6 distributor (very easy). then today i put a y8 trans in. oh yeah and when i put on the z6 head i gutted the cat as well. not bad for a months time. i'm pretty impressed.
