Want even more power out of your M3? The BMW S55 factory dual pump setup is already quite capable, however, there is always room for improvement. This is where the Nostrum S55 HPFP kit comes in. Flowing 36% more fuel than stock, the Nostrum HPFP’s will provide you with more fuel earlier in the rpm range. This allows you to dial in more boost down low, allowing for more low end torque, reach your peak power sooner, and hold that peak power for longer. The Nostrum HPFP kit requires no permanent modifications, allowing you to revert your vehicle to stock in the future. Being that these pumps are installed just like the OEM pumps, the installation is far less involved than a vacuum pump style kit.
Our pumps are completely ethanol compatible, giving you the added benefit of being able to run e85 or blended ethanol fuel. Ethanol is wonderful on turbo cars, as it has a higher octane rating and is less prone to knock than 91/93 pump gas.
Bundle up and save big! Take full advantage of your Nostrum HPFP’s by pairing them with our Stage 2 injectors, the largest available on the market! Flowing 55% more fuel than the stock S55 injectors, our Stage 2 injectors allow for significant gains in peak horsepower, when properly tuned. Bundling the HPFP’s and injectors together turns the S55 into a monster of an engine!
These products come complete with everything you need inside the box, including detailed installation instructions. Nostrum backs every part we sell with a limited lifetime warranty. 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 Asked Questions
Q: Is this pump kit compatible with aftermarket port/meth injection kits or the Dorch lift kit?
A: Our pumps are not compatible with the Dorch lift kits. Due to the variety and variation in aftermarket supplemental fuel systems, we cannot guarantee fitment with all aftermarket parts. Certain meth injection systems will obstruct the installation of our pumps due to their injection plate before the intake manifold. For additional fuel capacity, we recommend bundlinge up to a Stage 2 or Stage 3 fuel bundle and avoid the complexities and risks with supplemental systems! Known compatibility issues with: Dorch Lift Kit, Certain Water/Meth spray kits
Q: My pump is making a chirping sound, is my car about to explode?
A: No, your car will not explode. The chirping sound is due to improper calibration and is caused by running fuel pressure above 18 MPa. After extensive in-house vehicle development on multiple vehicles, our calibration team has addressed these scenarios and proper adherence to our tuning guide will eliminate any issues.
