Does anyone know the specifications of the Turbo in the 2015 MCS and the specifications on the JCW? I was wondering if the turbos were different in the two. Thanks!

 

They're still listed as the same part number on RealOEM and etk.cc. As for specs, the most I know right now is they're MHI turbos (Mitsubishi). After that, we'll have to measure/investigate. Very probably they're BMW-specific, so the only real comparisons we'll be able to do are compressor and turbine inducer and exducer diameters along with possibly measuring A/R.
