Gemini Stage-6 Nitrous Kit w/10lb Bottle - 4150

The Gemini Stage-6 Nitrous Kit w/10lb Bottle is a wet-type single-stage nitrous oxide system engineered for engine builders, performance technicians, and motorsport enthusiasts seeking reliable power augmentation in the 50–300 HP range. This complete kit from Nitrous Express delivers consistent boost across the RPM band without complexity, making it the choice for street cars, bracket racers, and high-performance builds where straightforward installation and proven reliability matter.

The wet-stage design injects both nitrous oxide and fuel through a single nozzle, optimizing air-fuel ratio consistency and reducing jetting complexity compared to dry systems. The Gemini platform uses precision regulator technology and quality stainless steel plumbing to maintain stable bottle pressure throughout the power band. The 10 lb aluminum bottle is lightweight yet robust, and the white powder-coated finish resists corrosion in engine bays and race environments. Stage-6 calibration allows fine tuning within the 50–300 HP window, accommodating modest engine builds up to heavily modified applications without requiring multiple kits.

Installers and tuners appreciate the Gemini's straightforward manifold and solenoid layout—no external feed lines or complex electronics to troubleshoot. Competitive racers favor this system for bracket racing, street elimination, and naturally aspirated engines where transient response and heat rejection matter most. The 10 lb bottle capacity supports multiple passes on a single charge, and standard 1/4 in NPT ports integrate with common fuel rails and carburetors. Proper tuning, fuel management, and nitrous system maintenance—including post-run bottle purging—are essential to maximize engine longevity and consistent performance.
