I am new to the turbo community, and tried to install (turbo kit) today. but had no luck. The problem was the turbo housing kept on hitting the side wall of the block. i was going to shave it down, but it was not a corner of the block. does the exhaust manifold have to come out an inch? Or does something else needs to be purchased. (ebay D series turbokit, going on a D15 B7 95 coupe).
