Compared FP to the stocker manni and took some measurements. Distance from the exhaust flange to the inlet flange on the stock was 4.25", FP 4.75". Put manifold exhaust flange down on table, used a straight edge on flat surface of inlet flange. Then measured distance from straight edge on table to exhaust flange mounting hole. Stock was 1.7055", FP 1.459".

With the FP manifold the turbo was sitting half inch closer to the engine and a quarter inch higher. No wonder the PBM was hitting the bellhousing and underside of car.

On a side note. Does Greddy actually think u can run their turbo studs and get a lock washer and nut to fit?!? I'm not comfortable with only 1.5 threads holding my turbo elbow on.
