MuchBoost B58 hybrid turbo, BMW M140 i (F20/F21), 600–650 hp

A bolt-on MuchBoost hybrid turbo for applications including BMW M140 i (F20/F21), BMW M240 i (F22/F23). This upgrade is built for B58 applications and retains a clean, vehicle-specific installation.

The upgraded compressor and higher-flow turbine sides provide considerably more capacity than the factory unit. The housings are precision-machined for the new internals and the complete core is balanced at high shaft speeds.

Depending on the selected version, the manufacturer rates the turbo for approximately 600–650 hp. Final output depends on engine condition, the fuel system, intake, exhaust, cooling and, above all, the ECU calibration.

An upgraded turbo always requires vehicle-specific ECU calibration.
