Dorch Engineering EWG N55 49% Lift Kit HPFP Upgrade - with $400 core charge

Product Details

Take your EWG N55 to the next level with the Dorch Engineering HPFP Lift Kit. Engineered specifically for high power builds that push the direct injection threshold, this lift kit overrides the typical N55 fueling bottleneck by overdriving the high pressure fuel pump mechanism. Dorch installs their high lift fuel cam directly into a genuine BMW vacuum pump assembly. The result is a direct injection solution that drives up to 49% more volume into your fuel rail. For track street builds demanding extreme E85 flow, this kit provides the hardware necessary to sustain extreme target pressures without having to resort to port-injection setups.
