MuchBoost B57D30 Upgraded Turbocharger with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. It is based on an original Honeywell GTD2056VZK & GTB2260VK turbochargers, which means that the installation is 100%P&P. The turbocharger is meant to work with BMW 530d, 630d, 730d, X3 with the B57D30 210-265HP engines.

The turbo delivers up to 190% power (190 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 400HP to 450HP.

MuchBoost B57D30 400

Upgraded turbocharger with an estimated ~400HP at the crank. List of modifications:

  • Precisely machined seal plates and compressor housing,
  • Genuine Honeywell compressor housing,
  • Genuine Honeywell bearing housing,
  • Genuine Honeywell exhaust manifold,
  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • Genuine Hella electronic actuator
  • More efficient and larger Billet Compressor Wheel GEN II,
  • High-Flow 9 Blades GTD22VZ genuine Turbine Wheel,
  • 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.
