More fuel capacity for the boost you want to use.

When fuelling is limiting your Mustang, changing the pump alone can leave the injectors as the next restriction. This Stage 2 bundle upgrades both together: a Big Bore HPFP with 63% more flow than stock and four direct injectors flowing 22% more than the original 2.3 EcoBoost injectors. It gives your tuner more capacity to work with while keeping direct injection under the factory ECU.

SKU: H186-1532

Why upgrade the pump and injectors together?

The mechanically driven pump can limit fuel supply around peak torque, while the shorter time available to inject fuel at higher revs can make injector capacity the next limit. Upgrading both gives the calibration more room across the rev range. That is the appeal of the bundle when the car needs both changes, rather than paying for a pump upgrade and reopening the job later.

Capacity with usable injector control

The injectors flow 19.7 g/s at 100 bar and retain an OEM-equivalent spray pattern. The spray pattern matters because fuel needs to mix properly in the cylinder at everyday engine loads as well as at full throttle. The pump and injector specification supports a 240 bar maximum operating pressure.

This is extra fuelling capacity, not an automatic power figure. The turbo, fuel, engine hardware and calibration determine how much of that capacity your car can use.

What comes in the bundle

  • Big Bore high-pressure fuel pump kit.
  • Four upgraded direct injectors.
  • Application-specific high-pressure fuel line and fitting hardware.
  • Installation instructions and data sheet; tuning guidance available for the calibrator.

The pump uses the stock low-pressure feed connection. The bundle does not add a separate port-injection controller or methanol tank.

Choosing it for your car

For the 2015-2023 Ford Mustang 2.3 EcoBoost. This is the Mustang bundle, not the Focus RS kit; the pump installation hardware is application specific. It makes sense when the build needs both pump and injector capacity, including a calibrated ethanol build. The fuel system still needs to be sized around the actual engine and power target.

Installation and calibration

Arrange the calibration alongside fitting. The pump and injectors need the correct data in the ECU before the upgraded system is used. Your tuner should assess low-pressure supply, fuel choice and the rest of the engine build together, then validate the result in logs. The hardware purchase does not include a custom tune.

Warranty

Nostrum's limited lifetime warranty covers manufacturing defects in its manufactured parts, subject to its terms. Installation and removal labour, diagnostics, misuse and damage from incorrect installation or tuning are excluded.

Nostrum also excludes its returns and warranty claims where the vehicle is tuned by TunePlus.

Only need more pump capacity?

If your current injectors still meet the build's requirements, the application-specific HPFP kit is available separately. It does not include the injector upgrade supplied with this bundle.

Frequently asked questions

Why not just fit the pump?

A pump upgrade increases fuel supply, but the injectors still have to deliver it in the time available. The bundle is for a build that needs capacity in both parts of the direct-injection system.

Is it the same kit as the Focus RS version?

No. The vehicle-specific pump lines and installation hardware differ. Choose the bundle for your car.

Will fitting it automatically add power?

No. It adds fuelling capacity for a compatible calibration to use. Output depends on the turbo, fuel and supporting engine hardware.

Can I use ethanol fuel?

The fuel hardware is ethanol compatible. Use the blend specified by your calibration; ethanol-compatible parts do not automatically make the car a flex-fuel vehicle.

Is a tune included?

No. Book the custom calibration separately alongside installation.
