The Ranger Raptor's 3.0 V6 EcoBoost is a strong engine with an ordinary fuel pump behind it, and that pump is the first thing to fold when you add boost or ethanol. Nostrum's 1150-250 Big Bore kit replaces it with a welded stainless assembly flowing 47% more than standard, displacing 1.87 cc per revolution and working to 248 bar. It is the pump that has taken Ranger Raptors past the 650 whp mark, and Nostrum quotes the fuel delivery as supporting up to 750 whp on petrol or 700 whp on E85 in a fully built truck. The kit is complete: pump, mounting flange with its alignment tool, stainless high-pressure tubes with OEM fittings, the connector adapter harness and the install guide.
E85 carries a much higher effective octane, which is why it suppresses knock so well on a boosted V6 and lets a calibrator run more timing. The trade is volume: the engine wants substantially more fuel through the same pump for the same mixture. On a standard truck that shows up as falling rail pressure at the top of a pull, and the tuner protects it by pulling boost. With Big Bore fitted the pump stops setting the ceiling, and the calibration can chase drivability and torque delivery instead.

Big Bore is the sensible pump for a Raptor keeping its factory turbos on an ethanol map. The Goliath 1200-250 sits above it at 60% over standard flow and is aimed at trucks already past what Big Bore supports.
Yes, alongside normal pump petrol. If you plan to move between fuels, an ESSIM ethanol content analyzer lets the calibration read what is actually in the tank rather than assuming.
