Luke, I think the compressor position is virtually the same but the exhaust housing orientation is different and the dump pipe will also be slightly different. When I built my new manifold for the GT3076 I rotated the ehaust housing on the dump pipe then made a jig to hold the turbo while I made the manifold. My only regret is not moving the turbo away from the head slightly so a .70ar compressor housing could fit incase I feel the need to fit a larger turbo later on. With my current set up it is interchangeable between my 2wd and my custom manifold

As mark said, a good comparison will be pics of my car with 2wd manifold and GT3076 compared to his current set up[;^)]
