DOC Race E46 Topmount

Made some headway on the M3 Topmount positioning. Fit with a T4 PT67 turbo we are beginning to build the twinscroll merge collector for the setup.

With the turbo fit, we found a few other areas that were going to be addressed for retaining air conditioning and also air intake chambering. Even though were building a wangan style headlight for track day rips, were developing an intake charge system that is more inventive and realistic for day to day use without the road debris through the compressor.


With a few small adjustments this twinscroll setup looks promising for the sought after 42R frames; downpipe and wastegate setups are in the works..
