In terms of mechanical fitment, they drop directly into any N55 or S55 engine currently supported by Dorch Engineering's HPFP systems, making them the natural fueling upgrade once you're pushing past what the factory injectors can supply.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eFuel delivery capacity varies by fuel type: expect roughly 900-1000whp on E0\/E10 gasoline, and 720-800whp on E85, depending on your specific supporting build and tuning. As Dorch Engineering themselves note, when pushing much beyond the flow capacity of a standard Stage 2 HPFP kit, the N55 becomes limited by its factory injectors, so upgrading to these at minimum is highly recommended to see the full benefit of a bigger fuel pump upgrade.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e these injectors require coding via ISTA, along with proper tuning before running them.
