Stage 1 Plus is Nostrum's matched pair for the 2015-2023 Ford Mustang 2.3 EcoBoost: the Standard Bore Plus high pressure fuel pump with 37% more flow than factory, and a set of four batched high flow direct injectors flowing 22% more than the stock 2.3 injectors at 19.7 g/s at 100 bar. Doing both sides at once is the point. A pump alone lifts the mid-range, injectors alone lift the top end, and only the pair takes the fuel ceiling off a stock or full bolt-on car across the whole rev range. It also keeps everything inside the factory direct injection system, so there is no meth tank to fill, no secondary port injection controller to wire in and no extra failure point sitting outside the ECU's own diagnostics.
You get the fully welded stainless Standard Bore Plus HPFP with its mounting flange, low pressure fuel line, high pressure fuel tube and flange installation tool, plus four drop-in batched direct injectors, an installation guide and the injector data sheet. Batching matters more than it sounds: the four injectors are matched on flow, so the tuner is calibrating one consistent set rather than compensating for cylinder-to-cylinder scatter. If you only want the pump for now, the Standard Bore Plus kit is sold on its own.

Many of the products we sell are made to order, imported or custom built, so a lead time may apply. If you need a part urgently, contact us before ordering and we will confirm the expected delivery timeframe and process.
The injectors are the same high flow set; the pump is not. Stage 1 Plus uses the Standard Bore Plus pump at 37% flow, while Stage 2 uses the Big Bore at 63% for bigger turbo builds.
Not for the fuelling this bundle covers. It was put together so a stock or bolt-on 2.3 can be fed entirely through the factory direct injection system, including on pump E85.
Most Ford EcoBoost specialists can. Nostrum publishes tuning guides for dealers and tuners, so send the guide to whoever is doing your calibration before the car goes on the dyno.
