MuchBoost 2.7HDI Upgraded Turbochargers with Custom Billet Compressor Wheels and Clipped/Enlarged Turbine Wheels. They are based on original Garrett Turbochargers, which means that the installation is 100%P&P. The turbochargers are meant to work with Citreon C6, Peugeot 407, 407 Coupe, 407 SW, and 607 with the 2.7HDI DT17 204HP engines.

The turbos deliver up to 171% power (146 extra HP) over the factory specs. It is a great choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbos allow you to get more from your engine and enjoy it even more than you’ve been so far. The price is for 2 turbochargers with no core charges.

We have developed 2 modification options that allow you to reach anywhere from 300HP to 350HP.

MuchBoost 2.7HDI 300

Upgraded turbocharger with an estimated potential of ~300HP at the crank. The list of modifications:

  • Precisely machined seal plates and compressor housing,
  • Genuine Garrett  compressor housing,
  • Genuine Garrett bearing housing,
  • Genuine Garrett exhaust manifold,
  • Upgraded journal bearing system that allows the turbo to hold more boost,
  • Original actuators,
  • More efficient and larger Billet Compressor Wheels,
  • Clipped Turbine Wheels,
  • Perfectly calibrated VNT system + dynamically balanced. We use a modern VISCOM flow bench and Schenck balancing machines,
  • Dynamically balanced,
  • 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 2.7HDI 350

Upgraded turbocharger with an estimated potential of ~350HP at the crank. Modifications compared to the 300 option are the same except:

  • Bigger Compressor Wheel,
  • Larger Turbine Wheel,
  • Machined exhaust housing.
Extra upgrade option

There is also a Ceramic Ball Bearing Upgrade option available for the 350HP option. It provides a better spool and more low-end torque.

Other significant modifications

The turbo is meant to work with ~300-350HP In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.


A set of gaskets is included with every option you choose!
