Welcome to the home of the highest powered direct injection N55 cars on the planet! If your power goals extend beyond the capacity of our DS25 HPFP alone, be sure to check out your options of pairing it with our N55LK innovation.

We’re proud to introduce our latest 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 pump packaging to provide improved hose routing for even easier installations. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.

What does this mean? It means the most reliable and highest flowing N55 pump on the market just got even MORE reliable and even MORE flow! The DS25 is also designed to run efficiently all the way up to 250 bar in order to maximize the flow potential of upgraded DI injectors.

Just like our previous generation DS2 kit, there’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like the OEM pump. All of the safety and sophistication of the stock DME remain in place. Software changes are required to run this pump. If using MHD or Bootmod3, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to for the appropriate software implementation via WinOLS.

Beyond the pump performance, why choose Dorch?

  • LIFETIME WARRANTY: The reason we can offer this is simply because our pumps are THAT reliable. That said, on the slim chance you have an issue, we’ve got your back!
