These are the largest direct injectors Nostrum builds for the 2.0 and 2.3 EcoBoost, and they exist for one reason: a built engine on a big turbo eventually asks for more fuel per cycle than a standard-sized nozzle can deliver in the crank angle available. Each flows 1950 cc/min, a mass flow of 23.4 g/s at 100 bar, 45 percent more than the factory 2.3 injector and 61 percent more than the 2.0. They fit as a direct replacement with no adapters or modifications, carry double Teflon combustion seals, and keep the fuel system inside the factory ECU's management and diagnostics.
Nostrum's upgraded direct injector set is the everyday choice: 22 percent over the standard 2.3 and good to 240 bar. This Race set is a different tool. It roughly doubles that flow step, but the working pressure ceiling is 200 bar rather than 240, so the extra fuel comes from nozzle size instead of pressure. On a stock-turbo car that is the wrong trade; on a built engine that has run the smaller injector out of duty cycle it is the only way forward without a second injection system.
An injector this size needs a pump that can keep the rail fed, which is why Nostrum specifies the Big Bore pump alongside it and packages the pair in its Stage 3 bundles. Spray quality was engineered around the higher flow too, because a large nozzle with a poor plume brings knock, soot and bore wash with it.
These cover the 2015 onwards Focus ST and Focus RS and the 2015-2023 Mustang EcoBoost. A tune is required and does more work here than on a smaller injector, so use a tuner who knows the platform; Nostrum supports COBB across all three cars with SCT on the Mustang, and names JEM Sport, Panda Motorsports, ZFG Racing, Speedperf6rmanc3 and Livernois. Note the 200 bar ceiling when planning rail pressure. If you are unsure, use a professional fitter.

You can, but you give up 40 bar of working pressure for flow the engine cannot use. On a stock or hybrid turbo the smaller upgraded set is the better result.
Nostrum specifies it, and it makes sense: injectors this large empty the rail faster than a smaller pump fills it. The Focus RS Stage 3 bundle packages the two together.
Nostrum engineers the plume for atomisation quality at the higher flow rather than chasing volume alone, and the car keeps factory ECU management. Drivability then comes down to the calibration.
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.
