Someone is bound to know. Some details are here: http://en.wikipedia.org/wiki/BMW_M47I'll bet the later motor isn't compatible as it had balancing shafts. But I'm not sure either way.If you find some of the early model (85kw) cranks...and you could ship them to the States...demand is very high here since we really never had a diesel BMW. The 1980's 524td is a rare beast.
