There wasn't a thread on this particular subject (I searched)...so...
I'd like a RWD cast manifold for a RWD 3SGTE project I'm doing. I don't want a tubular steel one as they are prone to cracking (from personal experience). If the stock manifold worked in RWD it would be perfect. I don't want more than 300Hp (flywheel) in this project, so I don't need fancy manifolds. Just something tough and reliable.
I've considered a lot of options with the standard manifold. Simply spinning the turbo 180 degrees so the inlet faces towards the front of the engine, makes the compressor housing foul the oil cooler and in general the turbo is just too close to the block.
I've thought of a spacer piece that pushes the manifold further away from the engine and using extended length studs. About 40mm or so. This would let it fit when combined with a relocated oil cooler (already doing that). However dump pipe options are stupid thanks to the bellhousing and starter location.
What are people thoughts on this idea, combined with a modified bellhousing to locate the starter on the other side?
Unless there are aftermarket cast manifolds out there for this particular application?
