could it be causing this. when i'm driving it sounds like a turbo is spooling up . it varies with rpms and.......i dunno its just weird and its pissin me off cuz i want boost so damn badly!

haha, yes, that could be causing it. I had the sound on one of my NA's. It wouldn't go away with tightening or loosening the belt. It went away when I removed the AP.

it could also be your throwout bearing...does it go away when you push the clutch pedal in?
