Late for soccer practice? The Nostrum HPFP upgrade is the first step to unlocking more power in your Explorer ST. Flowing 47% more fuel than the stock pump, our HPFP opens up a whole new world of possibilities and benefits. That additional flow allows for more torque delivery and more boost earlier in the rev range, giving you noticeable gains on even a mostly stock vehicle.

Take full advantage of your upgraded Nostrum HPFP by pairing it with Nostrum Stage 1 injectors. The stock injectors simply can’t keep up with the massive amout of fuel that our HPFP is capable of moving. Our Stage 1 Injectors give you 11% more flow than the stock injectors, raising the ceiling on how much power you can make. The Stage 1 bundle is great for anyone with minor bolt-ons and stock turbos, who is just looking for some more pep out of their daily driver. If you plan on going with bigger turbos or potentially even a built engine, the Stage 2 bundle is what you are looking for!

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.

The additional fuel provided by Nostrum’s hpfp will allow you to hit peak power even sooner. 
 
To take advantage of your now upgraded HPFP, we paired it with some bigger injectors!  Our Stage 2 injectors flow an additional 27% more fuel than the stock injectors. This is where we bring those peak gains back to the table. The Stage 2's are for those taking their build to the next level with all the bolt-ons and . If you are looking to push your Ecoboost to the absolute limit, you want the Stage 3 injectors! These are intended for those with built engines, built transmissions, and big turbos!

STAGE 3:

This kit includes the all new Stage 3 injectors and HPFP kit for 1 great price!


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!

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.

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!  

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!).  

 

Q: I need new injector seals! Do you guys have spares?

A: While we do carry some replacement seals, we have actually found it is more cost effective and usually quicker for customers to purchase part number: CM5314 from their local Ford dealer, as it will include all of the seals that you will need for your injectors!
NOTE: Those kits only service 3 injectors, you will need to purchase 2 kits!
