MuchBoost M47TuD20 /  M47D20 Upgraded Turbocharger with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. It is based on an original Garrett Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with BMW 318D & 320D E46 with the M47TuD20 /  M47D20 engines with a stock power of 116 / 150HP.

The turbo delivers up to 167% power (100 extra HP) over the factory specs. It is a great choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.

We have developed 2 modification options that allow you to reach anywhere from 230HP to 250HP.

Upgraded turbocharger with an estimated ~230HP at the crank. List of modifications:
