What sets Nostrum apart:

  • Largest 3.0L EcoBoost GDI injector available-96% larger than a factory 3.0 EB Injector
  • Direct replacement  
  • OEM comparable spray pattern  
  • Limited Lifetime Warranty 
  • Installation guide provided 
  • Ethanol compatible  
  • Allows operation of engine at significantly reduced fuel rail pressure while still achieving very high power levels

They’re finally here! The long awaited and highly anticipated Stage 3 injectors for the 3.0L Ecoboost Ford Explorer ST are now available. With a mind-blowing increase of 96% more fuel than the stock injector, the Stage 3s are what you want when you have a built engine, larger turbos, and the desire to push them to the absolute limit. 

Why Stage 3? More flow of course! One of the hurdles with DI is that as you increase pump pressure, the volumetric efficiency goes down. By lowering commanded pressure from 24 MPa to 20 MPa, the pump gains approximately 5% in flow rate that the Stage 3's are able to take advantage of! More flow, more horsepower!

For Stock Turbo or FBO cars, the Stage 2 injectors are what you want! They can be found here: Explorer Stage 2 Injectors

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 that remove layers of protection and safety from your engine. Our injectors operate with all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system! 

Inside the box, you will find everything you need to get your new injectors installed quickly, including detailed application specific instructions for a no-nonsense install. When you are ready to tune, we can get you set up with one of our trusted certified tuners, or we have injector tuning data available for your existing tuner.  

Take your Nostrum Stage 3 injectors to the limit by pairing them with our HPFP upgrade kit, flowing an incredible 47% more fuel than the stock pumps! 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.

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.

Horsepower and Torque numbers are approximate and can vary significantly depending on numerous factors including what supporting upgrades are done to the vehicle, ambient temperature, elevation, road surface, tire selection & condition, fuel octane and quality, vehicle weight, and more.  The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications.  Your results may vary.

 

Mat and Kathy's Explorer ST made 639 WHP on our Dyno on Pump E85! They went on to run a 10.67 in the quarter mile at the 2023 Shootout by Buschur Racing! See the run on Instagram here!

FAQ's:

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!  

Q: What is the difference between the Stages (for injector and bundles)? 

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.
