Nitro-Port Cast, LS3 1000 HP Loaded/ Short LS3 Port Intake/Cable Driven 102mm Throttle Body

The Nitro-Port Series Cast Manifold. Engineered for serious street and strip enthusiasts, this new manifold brings power, precision, and versatility to LS1 and LS3 platforms.

Designed with performance and adaptability in mind, the Nitro-Port manifold features a low-profile, modular design ideal for tight engine bays while delivering aggressive performance gains. Short runners support high-RPM power, and -8 AN fuel rails with -8 ORB fittings ensure consistent high-flow fuel delivery under demanding conditions.

For those pushing the limits, integrated nitrous/water injection bungs offer easy expandability, while rear-mounted vacuum and pressure ports keep plumbing clean and accessible. The manifold also features a rear-mounted MAP sensor location for simplified installation.

The Nitro-Port accepts 92mm, 102mm, and drive-by-wire* throttle bodies with a straight throttle body mounting flange, allowing builders more flexibility across multiple LS configurations.

Whether you’re building a high-revving track machine or a show-stopping street car, the FiTech Nitro-Port Cast Manifold delivers the performance, reliability, and engineering excellence customers expect from FiTech Fuel Injection.
