What sets Nostrum apart:

63% more HPFP flow than stock
Direct fit, no harness or spacers required
Comprehensive install solution - everything you need is in the box!
Ethanol compatible
Includes comprehensive installation guide

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.

All of our 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.

We have created the ultimate bolt-on fuel solution by bundling our HPFP kit with our high flow injectors! Save some cash and bundle your new HPFP with our Stage 1 or Stage 2 injectors!

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.

Frequently asked questions:

Is this compatible with the Gen 2 B58?

The Gen 1 HPFP & injectors are compatible with the Gen 1 B58 only. The Gen 2 B58, like the one found in the A90 Supra, uses a 350 bar high pressure fuel system from the factory, where the Gen 1 engine uses a 250 bar system.

Be sure to follow our social media for all of our future B58 developments!

Is the HPFP compatible with aftermarket camshafts?

Our Big Bore HPFP kit is intended to be used with the factory B58 Gen 1 camshaft. We cannot guarantee compatibility with aftermarket parts.
