MuchBoost B47C20 hybrid turbo set, BMW 125d F20/F21 (330 hp)

MuchBoost B47C20 hybrid turbo set, BMW 125d F20/F21, 330 hp

A bolt-on MuchBoost hybrid turbo set for applications including BMW 125d F20/F21, BMW 225d F22/F23. This upgrade is built for B47C20 applications and retains a clean, vehicle-specific installation.

The turbo is based on original Garrett housings. The upgraded compressor and higher-flow turbine sides provide considerably more capacity than the factory unit, while the housings are precision-machined for the new internals.

Depending on the selected version, the manufacturer rates the turbo for approximately 330 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.

Futurez imports MuchBoost turbochargers and works with the manufacturer in Finland. You get secure delivery from a Finnish seller, a wide choice of payment methods and help selecting the correct turbo version. Every purchase also earns F* Bonus points.

Before ordering, check the engine code and the identification numbers on the original turbo. If you are unsure about fitment, contact us with the VIN and the old turbo numbers and we will help verify the correct version.

Tip: Ask us for the gaskets, bolts, oil lines and other installation parts at the same time. A new turbo should not be installed with a restricted oil feed or leaking gaskets.

MuchBoost turbochargers carry a 12-month manufacturer warranty covering manufacturing and material defects. The warranty does not cover failures caused by external factors such as lubrication problems, unsuitable engine calibration or installation errors.
