MuchBoost N57N Upgraded Turbocharger with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. It is based on an original GTB2056VZK Garrett Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with BMW 330d F30, 430d F32, 530d F11, X5 30dx F15 with the N57N 258HP engine.

The turbo delivers up to 174% power (192 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 3 modification options that allow you to reach anywhere from +350HP to 450HP.

MuchBoost N57N +350

Upgraded turbocharger with an estimated +350HP at the crank. List of modifications:
