it's actually not that expensive to do...i did some snooping on CRSX...i know im going to hell for going to that site...but a2 cams 100 bucks to 120 buck, new springs and retainers another 100-150, and reflash 300 somthing, then upgrade to kpro 700 something, tune 300-400 bucks, supporting CAI, RH, midpipe another 700 bucks. Then you'll be cool with a A3...a little over 2000 spent on the A3...less then getting a A2 w or w/o kpro, less than a k24a1 w or w/o kpro...but i don't know how reliable it is, I actually thought about doing this, but then i kicked the boy racer's ass inside of me. And i'm getting married.
