The Dorch Engineering DS3 (Dorch Stage 3) is the highest flowing single pump solution for the Gen1 B58, with Dorch's largest bore size to date and around 20% more fuelling than the DS25.
It retains the same reliable OEM drop-in design, with OEM hose routing for zero interference when changing coil packs or spark plugs and an included OEM-quality high pressure line. Combined with Dorch injectors and camshaft upgrades, it opens the door to four-figure direct-injection power.
Please note:
- Software changes are required to run this pump. Bootmod3, MHD and MG Flasher users can simply select the Dorch pump upgrade when flashing; otherwise a custom WinOLS calibration will be needed.
- Please select the option to suit your car. Only suitable for Gen1 B58 vehicles up to the 2019 model year – not compatible with 2020-on B58 vehicles.
