Add at the end of 9.1.4.G.1: "It is permitted to use the OEM intake and throttle body for either the chassis or the installed engine."
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.
