Unlock your Ecoboost Mustang’s true potential with Nostrum's Stage 2 fuel system! Including our High Flow Ecoboost injectors and a Big Bore HPFP, this fuel system is designed to give your 2.3 as much fuel as it could ever need, without having to rely on meth or port injection! From mild stock turbo daily drivers to fully built record breakers, you can count on Nostrum to keep you fueling good!

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 450 wheel horsepower -  without the need for secondary injection!  

Take help you take full advantage of your Nostrum injectors, we paired them with our Big Bore HPFP, which flows an incredible 63% more fuel than the stock pump! 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!

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.

Why is spray pattern important?

While increasing flow rate is critical to making more horsepower, there are other factors to consider when choosing fuel system upgrades. A bigger injector isn’t always a better injector! It can flow a large volume of fuel at WOT, but if the spray pattern is poor, you can expect poor idle quality, poor drivability, increased knock propensity, soot, NVH (noise vibration harshness,) and tuning difficulty. Additionally, the wrong spray pattern can result in liquid fuel impinging in the cylinder walls, causing oil dilution, which increases mechanical wear to internal engine components.

Nostrum has invested significant time and resources into acquiring the equipment and machinery necessary to deliver an OEM level of quality on our injectors. Our spray patternation and arc flash machines (images below) give us an unparalleled look at how an OEM injector is designed and how it operates. Our engineers design and develop injectors to optimally interact with engine air flow inside the combustion chamber to improve fuel evaporation and create a homogenous air-fuel mixture that results in a higher combustion quality. For you, this means that you can expect our injectors to perform at their absolute best regardless of what you are asking from them, from daily driver duty to setting new ¼ mile records.

Frequently ask questions:

Q: What is the difference between the Stages? 

A: The specifications depend on the engine application. Usually the Stage 1 bundles are focused for stock-turbo FBO E85 builds and Stage 2 are focused on big turbo/built builds. In some cases we even expand to stage 3 depending on the capability of the platform, such as the Ford 3.0L EcoBoost and the BMW S55 platforms. The reason we offer stages is to satisfy multiple customer profiles, where the Stage 1 is offering more value and the Stage 2 is offering higher performance capability. This strategy is more customer centric then a one size fits all solution and we have seen very good success in all our other platforms.  

 

Q: Why don't I see horsepower gains with just a pump? 

A: Fundamentally we have to look at the entire fueling system and "where" in the rpm range the limits are. DI fuel systems in stock trim are often pump limited at middle rpm (peak torque) and injector limited at high rpm (peak power). This is due to engine speed. HPFPs are mechanically driven pumps (driven by the camshaft pump lobe spinning at ½ crank speed) and are RPM (engine speed) dependent. Many of the quoted flow increases in the aftermarket are purely displacement based comparisons: where by example the big bore pump has a piston diameter X% larger than the "stock" pump or the swept displacement ((3.14*(radius)^2)*(stroke))of the pump Y% larger than the stock pump. The larger displacement of the pump really shines in low rpm, where the fuel injector has plenty of time (crank angle degrees) to inject fuel. As the engines starts to approach peak power the engine speed starts to become quite short and is limiting the injection duration (crank angle degrees) for the injection event (which is another reason why we like to increase fuel pressure up high!).
