    You won't be able to run 300 bhp on a standard turbo mate. Look for around 240bhp until you get a garrett or VXR.

    to "bypass" the rear bcs do u just block it off and put the spacer in the recirc valve and run baileys?? surly that will give unsettled boost? isnt it the rear bcs that controlls the mid throttle boost??
