Nitrous Express EFI Kit

Model Number: 601200

The NX Stage 1 EFI 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 single Shark nozzle, nozzle mounting bung, Lightning series solenoids, 3AN stainless braided solenoid to nozzle lines, 4AN stainless braided nitrous feed line, 4AN fuel feed line, nickel plated fittings, wide open throttle switch, master arming switch, 40 Amp relay and relay harness, stainless bottle brackets and systems with a bottle include the the Lightning 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.

This system includes a 10lb nitrous bottle with the billet aluminum Lightning 500 bottle valve. This valve not only looks great; It is packed with features including two integrated gauge ports, 5/8 siphon tube, a large .500 orifice and an improved flow path with only one 45 degree turn. The Lightning bottle valve looks great, flows great and weighs nearly one full pound less than our old style brass valve.

    Do I need to buy any additional gauges to safely run this? Also, do I need to buy something that will act as a kill switch to the nitrous if the motor leans out?

      There are many ways to run nitrous. You can run it off a push button switch that you turn on and off, you could run it off of a full throttle switch, or you could for the ultimate setup, use a MSD window switch that only allows the nitrous to be used between certain rpms, and use that in conjunction with a full throttle switch. That way it will only work at full throttle and between your designated rpms. The last way is the most safest.
