This is the whole fuel-side answer for a Mk3 Focus ST: Nostrum's 1050-250 high pressure fuel pump and its high flow EcoBoost direct injectors, sold as one matched package. Each side adds 36 percent more flow than the factory part, and together they give a tuner enough supply and enough delivery to run E85 or a blend and bring boost in properly instead of tiptoeing around a falling rail pressure. The pump is laser-welded stainless and keeps the standard low-pressure feed line; the injectors are the same ones already proven on the Focus RS and EcoBoost Mustang. For an owner that means one workshop visit and one calibration session.
Worth being clear, because 2.0 EcoBoost is a wide family. Nostrum builds this package for the Ford Focus ST, 2015 to 2018. The 2013 and 2014 cars are still awaiting calibration validation. Other 2.0 EcoBoost models such as the Maverick have their own Nostrum kit rather than sharing this one, so match the vehicle rather than the engine size.
Buy these separately and one of them usually becomes the new restriction. The pump governs how much fuel reaches the rail, which runs short in the midrange as boost climbs. The injector governs how much goes into the cylinder in the crank angle available, which runs short at high rpm. Matching them is the difference between a car that pulls cleanly everywhere and one strong in half the rev range. If you only need the pump for now, the standalone Focus ST 1050-250 pump kit is the same unit.
A tune is required. Nostrum supports COBB, HP Tuners and SCT here, and names EMS, Dizzy Tuning, Stratified, Panda Motorworks and Tunewerks among its tuners. The 240 bar working pressure depends on the optional rail sensor; without it the system is limited by what the factory sensor reads. The standard low-pressure feed line is retained and fitting instructions are supplied. If you are unsure, use a professional fitter, and tell us if the car is an import.

Yes. This package is the pump kit plus the high flow EcoBoost injector set.
Nostrum builds this one for the Focus ST and a separate kit for the Maverick. For any other 2.0 EcoBoost model, ask us first rather than assuming the engine family is enough.
It is what unlocks the 240 bar ceiling. Higher pressure pushes more fuel through the same nozzle and improves spray as boost rises, so budget for it if you are aiming high.
Use the checked vehicle route, then confirm model year, engine, drivetrain, hardware and existing modifications on the product page or with our team before you commit.
Send us your vehicle, year, current setup and any fitting date, event, trip or deadline before ordering. We will help check fitment, product choice and timing.
