Description

The Zex LSX Nitrous System is a wet-style injection kit specifically fuel-tuned for GM LS-based engines, including the LS1, LS2, LS3, LS6, LS7, L99, and Gen III and Gen IV V8 platforms. These engines utilize higher fuel pressures (58 psi) and the system is engineered to handle these specific requirements for optimal performance gains. The kit is adjustable, allowing users to select between 75, 100, 125, 150, or 175 horsepower settings via included jets. Engineered with proprietary active fuel control, the system automatically monitors nitrous bottle pressure and adjusts the enrichment fuel flow to maintain a safe air-fuel ratio. Integration is simplified through the use of an electronic controller that connects to the vehicle's TPS sensor, ensuring nitrous flow is restricted to wide-open throttle positions. The kit includes an extra-long nitrous feed line to accommodate installation in F-bodied vehicle chassis configurations.
