Nostrum S55 Stage 2 Fuel System Bundle:
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. Also included in the bundle are a full set of Nostrum Stage 2 injectors.These are the largest injectors currently available on the market. They have been designed and tested to flow an incredible 55% more fuel than the stock S55 injectors, and 12% more fuel than the EU5 M5 injectors when compared to stock. 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 900 wheel horsepower, and have already fueled more than 700 wheel horsepower vehicles - without the need for secondary port or meth injection! Bundling the HPFP’s and injectors together turns the S55 into a monster of an engine!Nostrum backs every part we sell with a limited lifetime warranty. All Nostrum products 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.
