Unlike the S55 with its dual pump setup from the factory, the B58’s are stuck with a single HPFP which is one of the biggest limiting factors keeping you from making more horsepower. This is where the Nostrum B58 Gen 1 Big Bore kit comes in! Flowing an astounding 63% more fuel than stock, the Nostrum HPFP’s will provide your engine with the additional fuel it so desperately craves. The Nostrum HPFP kit requires no permanent modifications, allowing you to revert your vehicle to stock in the future.
All of Nostrum’s fuel system products 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.
Every Nostrum manufactured part is backed by a limited lifetime warranty. Their 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. Nostrum have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning.
