MuchBoost 2.5DCI Upgraded Turbocharger with a Custom Billet Compressor Wheel 7+7/11+0 Blades, and Clipped and Lightened/Enlarged Turbine Wheel. It is based on an original KKK Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Nissan Navara, Murano, and Pathfinder with the YD25DDTi 190HP engines.

The turbo delivers up to 157% power (110 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 250HP to 300HP.

MuchBoost YD25DDTi 250

Upgraded turbocharger with an estimated ~250HP at the crank. List of modifications:

  • Precisely machined seal plates and compressor housing,
  • Genuine KKK compressor housing,
  • Genuine KKK bearing housing,
  • Genuine KKK exhaust manifold,
  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • Genuine Hella actuator
  • More efficient and larger Billet Compressor Wheel 7+7 Blades GEN I,
  • Clipped and Lightened 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.
MuchBoost YD25DDTi 300

Upgraded turbocharger with an estimated potential of ~300HP at the crank. Modifications compared to the 250 option are the same except:

  • Bigger Compressor Billet Wheel 11+0 Blades,
  • Larger Turbine Wheel,
  • Precisely machined exhaust housing.
Other significant modifications

In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.
