Dorch Engineering BMW B58 Gen 1 DS25 HPFP Upgrade

From the creators of the world’s first B58 direct-injection fueling upgrades, Dorch Engineering proudly introduces the B58 Gen 1 DS25 HPFP, the next evolution in high-pressure fuel pump technology for Gen 1 B58 engines. Replacing the Dorch Stage 2 (DS2), the new B58 Gen 1 DS25 HPFP — also known as Stage 2.5 — has been completely redesigned and optimized to deliver greater fuel flow and improved reliability, making it the most advanced and highest flowing HPFP for Gen 1 B58 engines.

The B58 Gen 1 DS25 HPFP features a refined exterior design, with updated OEM-matched hose routing, ensuring zero interference when changing coil packs or spark plugs, and guaranteeing a clean, factory-like fitment. Installation is fully plug-and-play, requiring no cutting, bending, or crimping, and it operates under full DME control, retaining all factory safety features and sophisticated fuel system management.

Internally, the B58 Gen 1 DS25 HPFP is equipped with an optimized pressure chamber, revised spring rates, deeper plunger depth, and enhanced volumetric efficiency, all working together to provide superior fuel delivery under demanding conditions. Capable of running at up to 250 bar, this pump is designed to fully support upgraded direct-injection injectors, enabling higher horsepower builds, big turbos, and ethanol blends with maximum reliability.

Software changes are required to run the B58 Gen 1 DS25 HPFP. For users running Bootmod3, MHD, or MG Flasher, simply select the Dorch HPFP upgrade option when flashing your tune. If you’re using a custom tune, you can send your .BIN file directly to [email protected], and the Dorch calibration team will apply the necessary WinOLS adjustments for seamless operation.
