MuchBoost 2.0EcoBoost Upgraded Turbocharger with a Custom Billet Compressor Wheel and Clipped/Larger Turbine Wheel. It is based on an original BorgWarner Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Ford Focus MK3 ST 250 with the 2.0 EcoBoost 250HP engine.

The turbo delivers up to 140% 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 300HP to 350HP.

MuchBoost 2.0 EcoBoost 300

Upgraded turbocharger with an estimated ~300HP at the crank. List of modifications:

  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • More efficient and larger Billet Compressor Wheel,
  • Clipped and Lightened Turbine Wheel,
  • Genuine BorgWarner compressor housing,
  • Genuine BorgWarner bearing housing,
  • Genuine BorgWarner exhaust manifold,
  • Original actuator,
  • 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 2.0 EcoBoost 350

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

  • Even larger Billet Compressor Wheel,
  • Bigger 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. A reinforced actuator option is available with this turbo.

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