i got an 01 GSR with this set up, Comptech ice box, Competch Headers, SKunk2 intake, skunks2 cams stage 1, AEM 5 bolt cam gear, Apexi VAFC II, APEXI N1 exhuast) the cam gears and VAFC haven't put in yet... U will need to get a VAFC or ecu up grade otherwise u won't have a smooth power band, at least that is in my case with the things i have, that is why i got the VAFC and the cam gears so i can get it dyno tunned and set up so it has a smooth power band, (NOTE VAFC is not street legal) everything else i have is..
