MuchBoost GTB2056VK turbocharger professionally adapted to 1.9TDI, or 2.0TDI transverse and longitudinal VE, PD, and Common Rail engines (all the engine codes are mentioned at the bottom of this page.) The turbo is equipped with a Custom Billet Compressor Wheel GEN I 6+6 blades or GEN II 11+0 blades. The turbo is based on a genuine GTB2056VK from a Mercedes 3.0CDI V6 OM642 engine.

There are both more and less powerful with later, sooner spool, respectively. GTB1756VK  and GTD1756VRK  turbos have lower peak power but faster spool. The GTB2056VK is right in the middle. The GTB2260VK  produces higher peak power numbers with a later spool.

Main Features
  • The potential ~250HP~270HP,
  • Fast spool thanks to Billet Compressor Wheel 6+6 or 11+0 Blades,
  • Low manifold pressures at high RPM,
  • High air-fuel ratio including high peak torque achieved at low engine speeds.
Details on the construction of the turbo:
  • GTB20VK series machined compressor housing.
  • GTB20VK series bearing housing.
  • GTB20VK series exhaust housing.
  • The manifold comes from KKK or Garrett turbochargers (it depends on your stock turbo).
  • 56mm High Flow Compressor Wheel 6+6 blades GEN I or 11+0 blades GEN II.
  • Upgraded Journal bearing system that allows holding more boost.
  • GTB20VK 9 blades turbine wheel.
  • The turbo is cooled by oil only.
  • The EGR is deleted.
  • Garrett 3rd generation of VNT (Variable Nozzle Turbine).
  • The VNT actuator adaptation – standard vacuum or electronic (it depends on your stock turbo).
  • 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.
Mounting tips:

Steps to be performed during assembly:

  • The Installation of a larger DP (you will receive the flange with the turbocharger),
  • The Installation of Inlet&Outlet pipes (we recommend stainless steel).
Other significant modifications

The turbo is meant to work with ~250HP-~270HP at 33PSI35PSI of boost. In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.

GEN I 56mm Billet 6+6 blades34PSI260HP

The main difference between the wheel options:

  • 6+6 Blades GEN I – Better top range power, later spool,
  • 11+0 Blades GEN II– Faster spool, higher power potential.
