NOS GM EFI Nitrous Systems

Product images may differ from actual product appearance.

100 to 150 Horsepower



LT1 System
Those fortunate enough to have LT1 power in their Corvette, Camaro, or Trans Am can certainly appreciate the extra performance available a NOS system installation. Capable of producing 150 more HP and fully-adjustable. Supplied with all required hardware, electrical, plumbing, and detailed instructions.

LS1 System
Turn your late model Camaro into a 12 second rocket. This is a dry system that only injects nitrous oxide into the intake tract, relying on EFI to provide the extra fuel necessary. Easy to install and tune yet delivers an honest 125 horsepower. All required electronics are included to enable the OEM computer (ECU) to compensate for the additional fuel requirement on demand. Jets are included with the kit that allow the user to adjust power outputs to match available traction. The system can only be activated at wide open throttle and comes with a safety shut-off in the event fuel pressure drops below what is required to maintain adequate flow. Hardware, plumbing, detailed instructions, a 15 pound bottle, Super Hi-Flo valve, and nitrous pressure gauge are also included.

LS2 System
The LS2 system uses a billet plate with no spray bars. This unique design allows better atomization, which prevents puddles in the manifold and provides the best cylinder-to-cylinder distribution for maximum power. This is no ordinary kit...the plate and solenoids will easily support 250 HP.

TPI System
An easy-to-install 5.0L/5.7L system for 1985-92 Tuned Port Injection Camaro, including IROC and Z28, 1985-92 Firebird, and 1985-91 Corvette. Features a spray bar that mounts between throttle body and plenum. Able to be adjusted (with supplied jets) to produce between 100 and 150 extra HP. A throttle-activated micro switch is used for system activation. Each system comes with all required plumbing, hardware, and detailed instructions. Not for use on LT1 engines.
