Default How To Install Zex Wet Nitrous System...

Zex Wet Nitrous System for 2003-2006 Nissan 350Z

Zex Wet Nitrous Kit 82220 (for 2003-2006 Nissan 350Z)
Zex Nitrous Purge Kit 82010
Zex Liquid Filled Pressure Gauge 82341
Arm Switch
4 or 5 Pin Relay (The Window Switch will trigger the Relay to activate the Zex Controller)
JEGS 11206 Fuel Pressure Switch (To ensure the system shuts down if fuel pump fails)
MSD 8969 RPM Window Switch (To control what RPM the system starts and stops)
NGK PLFR6A-11 Spark Plugs (One Step Colder)
Add-A-Circuit Fuse Tap (To pick up power from the fuse block)
NOS 15551 Inline Nitrous Filter (Installed between the Bottle and the Controller)

Specific Tips for the 2003-2006 Nissan 350Z
1. The Throttle Position Sensor No.1 Wire is “Green” (Provides the Wide Open Throttle signal to the Zex Controller)
2. The No.1 Ignition Coil Wire is Black and Yellow (Provides the RPM signal to the Window Switch

3. Use the Resistor Wire included in the Zex Kit per the instructions
4. Install the “One Step Colder” Spark Plugs for the 55 and 75 HP shot (To prevent detonation)
5. Install the “Two Step Colder” Spark Plugs for the 100 HP shot (To prevent detonation)
6. Run High Octane Fuel (100+) to prevent detonation
7. Set the Window Switch above 2500 RPM for “System On”, Set below redline (6600 RPM) for “System Off” (You Do Not Want To Hit Redline Spraying Nitrous)
8. Bleed Fuel Pressure Off Before Installing Fuel Adapter By Removing The Fuel Pump Fuse (Located In Fuse Block Behind The Battery) And Then Cranking The Engine Over For Several Seconds.
9. The No.1 Cylinder Is The Right Side Forward (As Viewed From The Drivers Seat)
