[QUOTE="jimbixjr[/I]Will the turbo manifold from a M21 524td fit on a M30 engine? [/QUOTE] You may want to double check. My personal feeling is that it won't fit. The M21 Diesel engine is based on the M20 engine. The block of an M20 is much shorter than the block of an M30. This is also valid for their respective cylinder heads, and of course the exhaust manifolds.
