From the creators of the world’s first B58 direct-injection fueling upgrades, comes our next generation of pumps. Our widely successful “Dorch Stage 2” (DS2) has been replaced with our latest and greatest creation; the DS25! This new pump is our “Stage 2.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the packaging to provide exact OEM hose routing for ZERO interference when changing out coil packs or spark plugs. There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like factory. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.
Beyond the pump performance, why choose Dorch?
