Nitrous Express 90209-00 SX2 Dual Stage Direct Port Nitrous System 8 Nozzles 200-1200HP

The Nitrous Express SX2 Dual Stage Direct Port Nitrous System (90209-00) is a high-performance nitrous oxide injection system engineered for serious power applications ranging from 200 to 1,200 horsepower. This system is sold less bottle and is designed around NX's proprietary SX2 single-nozzle-per-port technology, the result of extensive research and development by the Nitrous Express design team.

Unlike conventional direct port systems that require two nozzles per cylinder, the SX2 uses a single nozzle per intake port, significantly reducing turbulence in the natural airflow path. This also eliminates the need to drill two sets of holes per cylinder, simplifying installation and improving reliability. Each SX2 nozzle is capable of delivering up to 300 horsepower per nozzle in either single or dual stage configuration, making this one of the most capable nozzle designs available.

This system uses nitrous and fuel rails in place of traditional distribution blocks, providing a cleaner, more consistent flow path. Installation requires drilling and tapping the intake manifold.

System Includes:

• 8 SX2 dual-stage nozzles — one per intake port
• 2 Super Shark nitrous solenoids — high-flow, high-response design
• 4 aluminum/carbon fiber Lightning fuel solenoids — lightweight and durable
• Stainless steel nitrous and fuel rails — replaces standard distribution blocks
• Stainless steel bottle brackets and hard lines
• Jetting and all necessary electrical components
