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 600HP.

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 600

Upgraded Turbocharger with an estimated potential of ~600HP 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.
