Unlike the S55 with its factory dual pump setup, the N55 is stuck with a single HPFP, which is one of the biggest limiting factors keeping you from making more horsepower.This is where the Nostrum N55 HPFP kit comes in! Flowing an astounding 63% more fuel than stock, the Nostrum HPFPs will provide your engine with the additional fuel it so depserately craves. 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 HPFPs 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 HPFPs and injectors together turns the N55 into a monster of an engine!
