BMW N54 Port Injection Conversion Kit

Convert your BMW N54 fuel system from factory piezo direct injection to port injection with Nexsys Motorsports integrated hardware and software package.

Off-road vehicle usage only. Not for road vehicles.

What it does

The N54 platform is capable of strong power, but the factory high-pressure fuel delivery system can become expensive to maintain and limiting for performance builds. This kit allows N54 owners to remove the direct injection components and move to a port injection fuel strategy.

Benefits of port injection

  • Lower repair and maintenance cost compared with N54 piezo direct injection components.
  • More injector flow options for upgraded fuel-system builds.
  • Increased usable injection window.
  • Fuel passes over the intake valves, helping reduce the need for walnut blasting.
  • Ability to remove direct injection components for reduced weight, parasitic loss, noise, and engine bay clutter.

Included

  • Press-fit direct injector bore plugs
  • Port injector harness and controller
  • High Pressure Fuel Pump block-off plate
  • Port Injection conversion kit license key required for flashing the vehicle

Required supporting components

  • Port fuel injectors
  • Boost-referenced fuel pressure regulator
  • Intake manifold with port fuel injector bungs
  • Fuel line to connect the low-pressure fuel system to the intake manifold rail while maintaining the low-side fuel pressure sensor
  • MHD Tuning flasher license for Nexsys custom code
  • For high-performance applications: upgraded low-pressure fuel pump(s) and upgraded fuel lines based on power goals
