MuchBoost N54B30 Upgraded Turbochargers with a High Flow Compressor Billet and Enlarged Turbine Wheels. It is based on an original Mitsubishi turbochargers, which means that installation is 100% P&P. The turbochargers are meant to work with BMW 135i, 1M, 335i, and Z4 with a 3.0 BiTurbo 306HP-340HP.

The turbo delivers great power characteristics and has something to offer for anyone that’s interested in driving a super-fast daily or someone trying to get into motorsport.

We have developed 3 modification options that allow you to reach anywhere from 450HP to 650HP.

MuchBoost N54 450

Upgraded turbocharger with an estimated ~450HP 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 genuine Turbine Wheel to help reduce backpressure,
• Genuine compressor housing,
• Genuine exhaust manifold,
• Genuine bearing housing,
• Original vacuum pressure 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 N54 510

Upgraded turbocharger with an estimated potential of ~510HP at the crank. Modifications compared to the 450 option are the same, except:

• even larger Billet Compressor Wheel,
• larger High-Flow 9 blade Turbine Wheel to provide much more flow and lower exhaust temperatures with higher boost,

Muchboost N54 650

Upgraded Turbocharger with an estimated potential of ~650HP at the crank. Modifications compared to the 510 option are the same except:

• Larger Turbine Wheel,
• Larger Compressor Wheel,
• 2.0″ Inlet.

Other Significant Modifications

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.
