Nostrum High Performance B58 Gen 1 Stage 2 Injectors

Fuel upgrades for the B58 Gen 1 are finally here! Our Stage 2 injectors are for those looking to take their Gen 1 B58 to the next level, without having to rely on secondary fueling. With 66% more fuel flow than the stock B58 Gen 1 injectors, the Stage 2’s will allow for a significant increase in horsepower, with proper tuning. We estimate that these injectors will flow enough fuel to make nearly 900 wheel horsepower

Inside the box, you will find everything you need to get your new injectors installed quickly, including detailed installation instructions. When you are ready to tune, we have injector tuning data available for your dealer or tuner. Being that everything is installed like a factory part, there’s no need to worry about secondary injection controllers, filling meth tanks, clogged meth injectors, or any of the other complex solutions people use to squeeze more power out of these vehicles. Additionally, these injectors are operating with all the OEM ECU’s engine management system diagnostics and safety functions – resulting in a much happier and responsive system!

Take full advantage of your Nostrum Stage 2 injectors by bundling up! The Stage 2 B58 bundle includes our upgraded high pressure fuel pump, flowing an incredible 63% more fuel than the stock pump! That additional fuel flow allows for significant torque increases earlier in the rev range, and provide the injectors with all the fuel they need to make more 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.
