Nitrous Express 4150 Gemini Stage 6 Nitrous Kit (50-300HP) w/o Bottle

This is the Nitrous Express 4150 Gemini Stage 6 Nitrous Kit, designed to fit standard 4150 flange carburetors. It's a comprehensive system for adding significant horsepower, offering adjustable power levels from 50 to 300 HP. This kit is ideal for those looking to extract more performance from their engine, particularly those with single-plane manifolds where distribution can be a challenge.

What sets the Gemini plate apart is its advanced direct-port pattern. Unlike traditional spray bar systems, this design ensures a more even distribution of nitrous and fuel directly into each intake runner. This means you get consistent cylinder filling and better atomization, leading to more reliable power gains. The plate itself is built to handle the demands of multiple stages of nitrous, and it eliminates common issues like spray bars sagging, splitting, or obstructing airflow. The kit includes everything you need to get started except for the nitrous bottle itself, featuring Lightning solenoids with a limited lifetime warranty, a heavy-duty 40-amp relay, stainless steel bottle brackets, and an extra 4AN long supply line.

With jetting included for 50, 100, 150, 200, 250, and 300 horsepower, you have the flexibility to tune your power output as needed. The improved flow path with only one 45-degree turn helps maintain optimal nitrous and fuel delivery. Remember that this system is not CARB approved and cannot be shipped to California.
