Nitrous Express Q-Jet/Holley Spread Bore Hitman Plus Nitrous Kit w/Composite Bottle

Nitrous Express is well-known for making nitrous oxide systems that offer a lot of performance for the money. This Hitman Plus kit is a great entry point for anyone looking to add a significant power boost to their carbureted engine without breaking the bank. It’s designed to work with Q-Jet and Holley spread bore carburetors, making it a versatile option for many classic muscle cars and trucks.

What sets this kit apart is its Phase 3 nitrous plate. Unlike older designs with spray bars that can sag or block airflow, this plate offers superior fuel and nitrous distribution for better atomization and more consistent power. It comes standard with four adjustable horsepower settings: 50, 100, 150, and 200 HP. The system also includes a Lightning 45 bottle valve, stainless steel bottle brackets, a 40-amp relay, and a wide-open throttle (WOT) switch with bracket, so you have most of what you need to get started.

This kit is designed to be upgradeable. If you decide you want even more power down the road, you can upgrade it to a Stage Six capability, potentially up to 300 HP with a larger nitrous solenoid and different jets. It’s a solid option for someone new to nitrous who wants a reliable system that can grow with their needs.
