Lol the cycle never stops!! I forgot about boost controller, that's definitely on the list. I have an intake but I'm probably going to fabricate a fresh air box thing to enclose it in. Exhaust wise, I have the stock piping minus the extra large stock muffler at the end, I might go with 3" CM piping with high flow cat and downpipe. If I get a boost controller though I'll only bring it up to 10-11psi just to be safe. Nistune anyone?? Ive been on redz31 site, i learned alot from there as well as zbums site, z31.com hasnt been working lately for some reason.
