Nostrum – B58 Gen 1 Stage 2 Bundle (H186-1780)

Unlike the previous 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. 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. We have created the ultimate bolt-on fuel solution by bundling our HPFP kit with our Stage 2 injectors! Flowing 66% more fuel than the stock B58 Gen 1 injectors, our Stage 2 injectors allow for significant gains in peak horsepower, when properly tuned. 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.
