DORCH ENGINEERING N55 Stage 2 HPFP
Stage 2 kit is a bigger, better version of our Stage 1 kit for some of the more extreme applications. This is a complete plug-and-play kit to support 650whp and also allow for full E85 up to 500whp (these numbers can vary quite a bit depending on tuning strategy, fuel type, etc.). 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.
