Do you want to get absolutely the most out of your engine? Muchboost has a solution for you!

Muchboost FCA GMR-T4 Hybrid Upgraded Turbocharger with a Custom Compressor Billet Wheel 6+6 and Enlarged/GT28 Turbine Wheel (depending on the option). It is based on an original Garrett turbocharger, which means that installation is 100% P&P. The turbocharger is meant to work with Alfa Romeo Giulia, Stelvio, Jeep Cherokee with the 2.0T TBi/T-GDI 200HP-280HP engines.

The turbo delivers great power characteristics and has something to offer for anyone that’s interested in gaining more power from their daily driver or trying to get maximum performance from their fun weekend car. You don’t have to worry about being taken over anymore.

We have developed 4 modification options that allow you to reach anywhere from 330HP to 430HP.

MuchBoost FCA GMR-T4 330

Upgraded turbocharger with an estimated ~330HP at the crank. List of modifications:

• Precisely machined seal plates and compressor housing,
• More efficient and larger Billet Compressor Wheel 6+6 blades,
• Upgraded journal bearing system that allows the turbo to hold more boost,
• Clipped and Lightened Turbine Wheel,
• Genuine Garrett compressor housing,
• Genuine Garrett exhaust manifold,
• Genuine Garrett bearing housing,
• Original Garrett electronic actuator,
• 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 FCA GMR-T4 370 – the most recommended version – provides moderate speed of spool with medium flow.

Upgraded turbocharger with an estimated potential of ~370HP at the crank. Modifications compared to the 330 option are the same, except:

• even larger Billet Compressor Wheel,
• larger Turbine Wheel to provide much more flow and lower exhaust temperatures with higher boost,
• Precisely machined exhaust housing.
