Not a Z owner, but I've got plenty of friends who used to own Civics or 350's and upgraded so I wanted to check in and say hi.
All I've got to commute in right now is this POS Civic:
I was fortunate in that most of the stuff on the car was obtained through sponsorships or were pre-produtcion prototypes. It's turbocharged @ 9psi with a Greddy kit, Magnaflow Exhaust, random carbon crap, coilovers, volks, ricer spoiler and body kit, bride seats, takata harnesses and a few other random tid-bits. If any of you feel like wasting 10 minutes of your life, you can read my build thread on the civic forums:

Anyways. I look forward to meeting you all and checking out all the 370z
and vids!
