Nitrous Express Nitrous Kit w/Billet LT4 Supercharger Lid w/o Bottle

This Nitrous Express kit starts with a solid piece of billet aluminum, machined to replace the factory upper lid on your GM LT4 supercharger. This isn't just a cosmetic upgrade; the 1/8 NPT ports are machined directly into the lid, allowing for direct port style distribution of nitrous and fuel into each cylinder. This setup offers a cleaner and more direct way to inject your performance fuel, compared to other methods.

The installation is designed to be quick and clean, integrating directly with your existing LT4 supercharger. The system comes standard as a single stage, with jetting options that can add anywhere from 100 to 300 horsepower, depending on your setup. The billet aluminum construction not only looks solid but also provides a robust platform for the injection ports. Plus, the machined ports make it straightforward to add a water/methanol injection system later on if you decide to further enhance your setup.

While this kit doesn't include the nitrous bottle itself, it provides the core components for a direct port nitrous system. It's important to note that this system is not CARB approved and cannot be shipped to California. For those looking to significantly increase power on their LT4-equipped vehicle, this offers a well-built solution for direct nitrous and fuel delivery.
