rotating the housing is dead easy on the gt25r you just pinch the big clip in the middle, it fits the standard pgt manifold and elbow, and the standard intake pipe fits on, only bits you need is custom oil feed, water pipes and intercooler pipe,
Fit standard manifold, need Dr Evil elbow which you already have.
You may need to mess about rotating the housing to get it to suit your engine but thats by the by.
