actually that happened to me... my car was on the dyno and the T4/66 bb turbo wouldnt make boost at all.. it was a new turbo that sat for 1 year.... the shaft was bent... after trailoring home, drove off the trailer... the fins scrapped the housing...


test the turbo by removing the ic coupler on the side of the turbo hit boost and see if there is enough pressure... if there is then its something else.. if not... we have a brand new full-race T3/67 turbo or used GT40 for sale.....

good luck
