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:

• Upgraded journal bearings system that allows the turbo to hold more boost,
• Genuine Hella electronic actuator
• More efficient and larger Billet Compressor Wheel 9+0 Blades GEN II,
  
• Bigger GTB22VZK Turbine Wheel.
• Genuine Garrett compressor housing,
• Genuine Garrett bearing housing,
• Genuine Garrett exhaust manifold,
• Dynamically balanced,
• Precisely machined compressor housing, exhaust housing and seal plate,
• Perfectly calibrated VNT system + dynamically balanced. We use a modern VISCOM flow bench and Schenck balancing machines,
• The compressor and turbine wheels are balanced separately, and then the whole core is high-speed balanced using VSR balancing machines at speeds similar to the level seen in the vehicle.

MuchBoost N57N +400

Upgraded turbocharger with an estimated potential of +400HP at the crank. Modifications compared to the +350 option are the same except:

• Bigger Compressor Billet Wheel 11+0 Blades GEN I,
