Hi flowed stage 2 factory borgwarner turbochargers. W205 turbo upgrade . Designed to handle 700hp+. These are a change over unit ( core replacement with your current turbo's as long as they can be rebuilt ). Direct fitment and replacement looking visually externally identical to oem standard. Tested and proven results. Upgrading both the compressor wheel 6+6 and the turbine wheel 9 blade and thrusts upgraded for running higher boost.
