Since there was a S54 powered Z3, then I can use that oem intake and throttle bodies, and add that to a M-50 motor. Note there's nothing about how to adapt the S54 throttle bodies onto a M-50 motor, so an adaptor/spacer plate is a perfectly legal way to mount it. If you don't like this change to the STCS, then you should contact the CRB, as per the August Fast-track.
Contact Karl Peoltl at RacersEdge about mating S54 TB's to that. His ex WC E46Tc car now has something like that and was turning 2:26's at RdAm in 2010 with the BMW club. see link here.> http://forums.bimmerforums.com/forum....php?t=1422245
