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 wastegates, 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.
Each turbocharger is VSR balanced to exceed OE tolerances with upgraded heavy-duty bearings and thrust washers.
Our turbochargers are designed to move a lot of air at lower boost levels, which means you can make some serious power without over-speeding the turbos, which means reliable performance.
Further performance can be gained using larger turbo inlets with this setup.
Installation and tuning must be performed by a qualified professional. Wastegate actuators MUST be calibrated using ISTA+ software before tuning.
