It combines the 2.3 Race direct injectors, flowing 45% more than the stock injectors, with the Big Bore high pressure fuel pump at 63% more flow than factory, plus the hardware, accessories and installation instructions. That pairing is aimed squarely at built engines running a large turbo, where the injector is the limit at the top of the rev range and the pump is the limit through the middle. As with the rest of the range it all stays inside the factory direct injection system, so the ECU keeps its own diagnostics and safety functions rather than handing fuelling to a secondary controller.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBuilt 2.3 EcoBoost Mustang engines with a large turbo already fitted\u003c\/li\u003e\n\u003cli\u003eDrag, track and record-chasing cars where fuelling has to hold at sustained high load\u003c\/li\u003e\n\u003cli\u003eOwners already on the Race injector step who need pump capacity to match\u003c\/li\u003e\n\u003cli\u003eHigh ethanol calibrations that ask far more of the fuel system than petrol does\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhen The Standard Upgraded Injectors Are Not Enough\u003c\/h2\u003e\u003cp\u003eNostrum's usual high flow injectors sit 22% above stock and cover most bolt-on and stock-turbo builds comfortably. The Race injectors were developed for the 2.0 and 2.3 EcoBoost engines that have moved beyond that: a built bottom end, a much larger compressor, and a fuel target the smaller injector simply cannot meet at high rpm.

The in-tank lift pump, fuel lines and any ethanol sensing are separate decisions that should be made with your tuner around the power target.\u003c\/p\u003e\u003ch3\u003eCan I fit the injectors now and the pump later?\u003c\/h3\u003e\u003cp\u003eYou can, but the pump becomes the limit almost immediately at this injector size, which is why Nostrum groups them.
