CTS Turbo Stage 2+ Turbo Upgrade - BMW S58 (M2 / M3 / M4 / X3 M / X4 M)

CTS Turbo is excited to announce the release of our latest Stage 2+ designed specifically for the BMW S58 platform. This kit builds on the success and knowledge for the previous turbo projects we have made and incorporates new technology to optimize performance and maintain factory fitment. Our engineers utilized transient flow analysis and flow bench testing to optimize the twin scroll turbine housing, while maintaining stock fitment, stock location, and using the stock wastegates. This allows for the use of any stock fitment downpipes, intakes, and charge pipes. The result is an impressive 825whp-900whp. You can simply transfer your factory wastegate controllers, high performance downpipes, intake and charge pipes during the install. No custom parts are needed and all factory installation hardware and gaskets are used! No need for cores to be sent in or purchased.

Fits: BMW S58: M3 (G80/G81), M4 (G82/G83), M2 (G87), X3 M (F97), X4 M (F98). Confirm your exact car with us before ordering.
