Who needs 8 cylinders to go fast? Introducing Nostrum High Flow Injectors for the 2.0/2.3 Ecoboost!

Our upgraded injectors have been designed and tested to flow 22% more fuel than the stock 2.3 injectors. That additional fuel flow allows for a significant increase in horsepower, with proper tuning. We estimate that these injectors will flow enough fuel to make over 700 wheel horsepower, and have already fueled a few vehicles making more than 500 wheel horsepower – without the need for secondary injection!  

Take help you take full advantage of your new Nostrum injectors, we recommend pairing them with our Standard Bore Plus HPFP, which flows 37% more fuel than the stock pump. With a higher max operating pressure than our regular standard bore pump, and having a lower cost than the Big Bore pump, the Standard Bore Plus unlocks even more horsepower potential, and allows you to take full advantage of our high flow injectors! This is perfect for anyone who is looking to get the most out of their stock turbo, or run pump E85! That additional fuel flow allows for significant torque increases earlier in the rev range, and provide the injectors with all the fuel they need to make more peak horsepower, when properly tuned. It also saves you money versus buying these parts individually!

Going with a big turbo? Want to hurt some V8 owners feelings? You’re going to want the Stage 2 bundle!

Inside the box, you will find everything you need to get your new fuel system installed quickly, including all the hardware and accessories that you need, as well as detailed installation instructions. When you are ready to tune, we have tuning guides available for your dealer or tuner. Being that everything is installed like a factory part, there’s no need to worry about secondary injection controllers, filling meth tanks, clogged meth injectors, or any of the other complex solutions people use to squeeze more power out of these vehicles. Additionally, these injectors are operating with all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system!  

Every Nostrum manufactured part is backed by a limited lifetime warranty. Our products are comprehensive solutions that come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your dealer or tuner. We have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning.

Frequently ask questions:

Q: Why do your numbers say I will make less horsepower on E85 than 93 octane? 

A: Great question! The numbers we list in the product descriptions are similar to the numbers a turbo charger lists for air flow. The numbers are the “fuel system capacity to generate power” regardless of the other engine system limitations (air handling, mechanical limitations, knock propensity). Essentially the numbers are calculated assuming “sufficiently large air flow”, “sufficiently capable mechanical assemblies” and disregarding knock limits. The equation uses actual observed engine volumetric efficiency (when available from sponsorship vehicles) and fuel capacity (including target pressures) to calculate power. Gasoline has more energy per mass volume than E85. So the higher fuel flow capacity will mathematically generate higher power potential for a gasoline than a high ethanol content fuel. The other variables (air flow, spark, rotating assembly strength, charge cooling, mechanical assembly strength) are highly variable from build to build. This is why we state horsepower capacity for the fuel system – representing the potential of the fuel system if you have all the other aspects of your build addressed!
