MuchBoost N47D20 Upgraded Turbocharger with a Custom Billet Compressor Wheel. It is based on an original Mitsubishi Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with BMW 120d F20/F21, 220d F22, 320d E90N/E91N/E92N/E93N/F30/F31/F34, 420d F32/F33/F36, 520d F07/F10/F11, X1 20d E84, and X3 20d F25 with the N47D20 163-184HP engines.

The turbo delivers up to 184% power (137 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 250HP to 300HP.

MuchBoost N47D20 250-260

Upgraded turbocharger with an estimated ~250-260HP at the crank. List of modifications:

• Precisely machined seal plates and compressor housing,
• More efficient and larger Custom Billet Compressor Wheel,
• Upgraded journal bearing system that allows the turbo to hold more boost,
• Clipped and Lightened Turbine Wheel,
• Genuine Mitsubishi compressor housing,
• Genuine Mitsubishi exhaust manifold,
• Genuine Mitsubishi bearing housing,
• Original Mitsubishi electronic actuator,
• 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 N47D20 290-300

Upgraded turbocharger with an estimated potential of ~290-300HP at the crank. Modifications compared to the 250-260 option are the same, except:

• larger Turbine Wheel to provide much more flow and lower exhaust temperatures with higher boost,
• 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 custom ECU tune will be necessary after mounting the turbo.

Example project

One of our clients managed to produce 196 HP at the wheels and 432 Nm of torque. The car was also equipped with an upgraded radiator. Please take a look at the dyno graph.

Another great example is this 120d that produced 296HP and 645Nm of torque. It was also equipped with:

• BMW B47 HPFP,
• Wagner Tuning EVO 2 Intercooler,
• Autobedrijf Gijsbertsen, Specialist in BMW fuel lines,
• RK Custom exhaust downpipe
