MuchBoost OM628 Upgraded Turbochargers with a Custom Billet Compressor Wheel and Clipped/Larger Turbine Wheel. They are based on original Garrett Turbochargers, which means that the installation is 100%P&P. The turbochargers are meant to work with Mercedes E-Class 400CDI W211, G-Class 400CDI W463, M-Class 400CDI W163, and S-Class 400CDI W220 with the OM628 250-260HP engine.

The turbo delivers up to 180% power (200 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 OM628 400

Upgraded turbocharger with an estimated ~400HP 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 Garrett compressor housing,
• Genuine Garrett bearing housing,
• Genuine Garrett exhaust manifold,
• Original actuator,
• 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 OM628 450

Upgraded turbocharger with an estimated potential of 450HP at the crank. Modifications compared to the 450 option are the same except:

• Bigger Compressor Billet Wheel,
• Bigger High Flow 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 set of gaskets is included with every option you choose!
