We have not yet looked at an X5M to see if it is possible. We have heard of some people installing the cross bank manifolds on the X5M and X6M. If that is something that can be done with out issue, then it is likely quite possible that the W.4 turbos will work when coupled with the cross bank manifolds.

The F8* X*M uses the same crossbank manifolds, the earlier E7* X*M's do not. It has been proven though that the S63 engine can use the S63TU headers with some light machining to the S63 turbo to header flange so they'll mate...I don't know if anyone has used S63TU headers AND S63TU turbos on an S63 engine, which means the machining wouldn't be needed.

Older X*M - http://www.realoem.com/bmw/enUS/show...diagId=11_4389

Newer X*M - http://www.realoem.com/bmw/enUS/show...diagId=11_5948

Point being, other than maybe some slight variations, there shouldn't be any reason the newer X*M couldn't use these turbos since it's truly the same TU engine as the M*.
