MuchBoost M47D 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  M47D engines with a stock power of 122-136HP.

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.

MuchBoost M47D 230

Upgraded turbocharger with an estimated ~230HP 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 6+6 Blades,
  • Genuine Clipped and Lightened Turbine Wheel,
  • Precisely machined seal plates and compressor housing,
  • Genuine Garrett compressor housing,
  • Genuine Garrett bearing housing,
  • Genuine Garrett exhaust manifold,
  • Original actuator,
  • Dynamically balanced,
  • 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 M47D 250

Upgraded turbocharger with an estimated potential of ~250HP at the crank. Modifications compared to the 230 option are the same except:

  • Enlarged Turbine Wheel,
  • Precisely machined exhaust housing.
Other significant modifications

The turbo is meant to work with ~230-250HP In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.
