Dorch Engineering BMW N55 Lift Kit – HPFP Upgrade

The Dorch Engineering N55 Lift Kit – HPFP Upgrade, a game-changing fuelling solution for the BMW N55 community, delivering up to 49% more fuel flow when paired with any of our existing N55 HPFP kits. This innovative upgrade allows higher horsepower capabilities than ever before using the OEM direct-injection fuel system, providing the fuelling capacity needed for high-boost, big-turbo, and ethanol-powered builds.

The N55 Lift Kit – HPFP Upgrade starts with Genuine BMW vacuum pump cores, where we install our proprietary Dorch Engineering cam using precision manufacturing tools and advanced validation equipment. The result is a clean, simple solution that dramatically increases fuel flow, all while retaining OEM reliability and utilizing the safety and sophistication of the factory DME. Unlike traditional fuelling upgrades, this system requires no cutting, bending, or crimping — it drops in like a factory part, seamlessly integrating into your N55 fuel system.

Best of all, the N55 Lift Kit – HPFP Upgrade works with factory DME logic, meaning no special tuning is required to get started, and all OEM safety protocols remain intact. For N55 enthusiasts pushing for big power on direct injection, this kit provides unmatched fuel flow potential with OEM-level fitment and reliability. Whether you’re chasing record-breaking horsepower or just want the most efficient fuelling solution available, the Dorch Engineering N55 Lift Kit – HPFP Upgrade is the ultimate performance upgrade for your BMW N55-powered F2X M135i/M235i, F3X 335i/435i, and F87 M2.

When combining the N55 Lift Kit – HPFP Upgrade with the Dorch DS25 HPFP (or DS2), it’s important to understand that there is a minimum power requirement for proper operation. This minimum power threshold ensures that your BMW N55 engine can be tuned easily and operate smoothly, maintaining OEM-like drivability. Running the N55LK + DS25 HPFP combo on lower power setups can create unnecessary challenges for your tuner, complicating the calibration process.

However, when combining the N55 Lift Kit – HPFP Upgrade with the Dorch DS15 HPFP (or DS1), there is no minimum power requirement. This makes the N55LK + DS15 HPFP combination the ideal fueling upgrade for a wide range of builds, from mild to high-power setups. With 49% more fuel flow on tap, this pairing supports everything from upgraded turbo setups to ethanol blends, while still maintaining OEM-level reliability and smooth drivability.

It’s important to note that software calibration changes are required to properly run the N55 Lift Kit – HPFP Upgrade. To make tuning easy, Dorch Engineering offers preset, optimized maps available through Bootmod3, with MHD support coming soon. Simply check the box for the appropriate “Lift Kit” upgrade when flashing your tune, and you’ll unlock the full potential of your N55 fuel system upgrade.

Whether you’re looking to maximize the performance of your N55-powered BMW M135i, M235i, 335i, 435i, or F87 M2, the Dorch Engineering N55 Lift Kit – HPFP Upgrade provides the fuelling capacity, tuning flexibility, and proven reliability to support your performance goals.

NOTES

When pushing much beyond the flow capacity of our existing Stage 2 HPFP kit, the N55 is very much limited by the injectors. In order to see the full potential of this upgrade, it is highly recommended to upgrade to the larger S63 EU5 Injectors. These are OEM BMW injectors that flow up to 800whp on full E85.
