Product Overview

The NX Stage 1 EFI Fly By Wire nitrous system is the top of the line EFI power booster on the market. From the billet aluminum and carbon fiber solenoids, to our patented Shark nozzle, this system screams nothing but quality. This system includes a TPS activated WOT module (for use with fly by wire throttle bodys), a single Shark nozzle, nozzle mounting bung, Lightning series solenoids, 24" D-3 stainless braided solenoid to nozzle lines, 15 Foot D-4 stainless braided nitrous feed line, 18" D-4 fuel feed line, direct plug in fuel rail adapter, nickel plated fittings, wide open throttle switch, master arming switch, 40 Amp relay, and relay harness. Some systems include stainless bottle brackets and a 5, 10, 12, or 15lb nitrous bottle with the lightning 45 bottle valve. This system includes jetting for 35, 50, 75, 100 and 150HP. The system can be easily upgraded later to support up to 250HP. This system includes the latest technology and the best components available. NX Lightning solenoids feature an improved flow path that eliminates sharp turns and expansion areas in the nitrous flow path. This keeps the nitrous in dense liquid form which makes more power on less nitrous. Lightning nitrous solenoids feature an integrated purge port which allows you to connect a purge valve directly to the body of the nitrous solenoid for clean looks and less plumbing. Lightning Series solenoids feature CNC aluminum bodies topped with Carbon Fiber cans for the ultimate in weight savings.The billet aluminum Lightning 45 bottle valve not only looks great; It is packed with features including an integrated gauge port, an integrated push port, a large .325 orifice and an improved flow path with only one 45 degree turn. The Lightning 45 bottle valve looks sexy, flows great and weighs nearly one full pound less than our old style NX 45 valve.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Nitrous System, 15 lb Bottle, Hemi/SRT8 Kit, Single Nozzle, Fly-By-Wire, 35-150 HP, Kit

It used to be that big horsepower increases required major internal engine modifications. However, Nitrous Express has a way that's a whole lot easier--and cheaper. Just bolting one of their EFI single nozzle nitrous systems onto your domestic or import can add from 35 to 150 hp to a V8, with intermediate choices of 50, 75, and 100 hp (with a maximum of 75 hp for fours and sixes.) These systems rely on a Nitrous Express Shark performance nozzle and will work with standard fuel pumps, without any timing retard. The kits include the nitrous bottle, nozzle, hoses, solenoids, wiring, and mounting hardware.
