MuchBoost B47D20 upgraded hybrid turbocharger with Custom Billet Compressor Wheels 11+0 Gen II and an Enlarged Turbine Wheel. It is based on a genuine Garrett turbocharger, which means that the installation is 100% P&P. The turbocharger is meant to work with 120D F20/F21, 220D F22/F23, 320D F30/F31/F34, 420D F32, 520D G30/F10/F11, X3 G01/F25 and other with the B47D20 150-190Hp engine. 

Our Hybrid Turbocharger allows your car to feel more agile and sporty. It is a great choice for someone looking for a quick daily driver with more power. Our Turbo allows you to get 200% (150 extra HP) more power than the stock figures.

We have developed 2 modification options that allow you to reach anywhere from 260HP to 300HP.

MuchBoost B47D20 260

Upgraded turbocharger with an estimated potential of ~260HP at the crank. The list of modifications:

• Precisely machined compressor housing,
• Genuine Garrett Ceramic Ball Bearings system provides a faster spool,
• Genuine Garrett  compressor housing,
• Genuine Garrett bearing housing,
• Genuine Garrett exhaust manifold,
• The turbo is cooled just by oil (no complication with water cooling fittings),
• Original actuator,
• Enlarged Billet Compressor Wheel 11+0 GEN II,
• 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 B47D20 300

Upgraded turbocharger with an estimated potential of ~300HP at the crank. Modifications compared to the 260 option are the same except:

• Larger Turbine Wheel,
• Machined exhaust housing.

Other significant modifications

The turbo allows you to get 260-300HP at the crank. To fully utilize the potential of this hybrid turbo, we recommend upgrading i.a. fuel, exhaust, cooling systems, and the clutch. Individual ECU remapping is the foundation.
