Show original supplier description
The Nitrous Express 20933-10 is a GM LS 102mm nitrous plate system designed to deliver a significant power boost, ranging from 50 to 400 horsepower. This wet, single-stage system features a billet plate that is compatible with all FAST 102 intakes, allowing for a straightforward installation between the throttle body and the intake manifold. The system comes with jetting for various power levels including 50, 100, 150, 200, 250, 300, 350, and 400 horsepower. Engineered with advanced technology, this kit includes ProPower Lightning series solenoids, which feature an improved flow path that maintains nitrous in a dense liquid form for maximum power output. These solenoids also have an integrated purge port for a cleaner appearance and reduced plumbing. The Lightning Series solenoids boast CNC aluminum bodies topped with carbon fiber cans for reduced weight. The system is pre-machined with provisions for a second set of nitrous and fuel passages, enabling an easy upgrade to a dual-stage system by adding part # NX933D. Included in the kit are all necessary components for installation, such as a 6AN feedline, braided stainless solenoid to plate lines, stainless bottle brackets, a master arming switch, and a WOT switch. The kit also comes with a 10lb white bottle and stainless braided hoses.
