HOME/MODIFICATIONS/Zex nitrous kit installation

Tools needed:

• battery powered drill with a number of different drill bits
• a soldering iron with flux and electrical solder (for wiring)
• wrenches: 7/16, 1/2, and 9/16; 2 of each
• flashlight
• hot glue gun or a really good epoxy glue (never know when you need it)
• 10mm socket and a ratchet
• a marker to mark drilling points

Recomended Preparations:

• new timing belt and water pump
• valves adjusted (valve lash)
• compression test
• diagnosis check
• use Magnecor KV85 wires and ZEX spark plugs
• A full tank of high/premium octane (92) gas
  

Step 1: Running the Main Line

I chose to locate the nitrous tank in the trunk. You may choose to locate your bottle elsewhere, the instructions should be very similar.

The kit comes with all the needed components for locating the tank in your trunk. Using the 15ft main nitrous line start with one end in the trunk. I ran the line through an existing hole under the spare tire up to the front of the car. You have the option of running the line through the interior of the car, which is much faster, however having the line under the car is safer and recommended by Zex. I zip-tied the nitrous line to the plastic bracket and followed the fuel line all the way to the engine (see image above). It helps to have someone grab the line when passing it up the port hole in your engine bay. For now leave, leave the line loose as there is quite a bit more to do =)

Step 2:Tank Brackets/Bottle Installation

The NOS bottle is comparable to a can of spray paint...it needs to be upright and tilted in the right direction to work correctly. The nitrous needs to freely flow through the main line, so you will need to mount the bottle in a position where the hose is always at the bottom corner of the bottle even during acceleration. Take note that the brackets are different sizes to mount the bottle correctly. The tall bracket goes on the nozzle end of the bottle while the small bracket goes on the butt-end of the bottle.

The tank brackets can be very difficult to install. I strongly recommend that you use 2 people for this step.
to mount the bracket you need to drill 4 holes in your trunk. Be aware of what you are drilling into and what is near before you start drilling and there shouldn't be a problem.

You really can mount the tank anywhere in the trunk. I mounted the bottle to the left of my CD Changer & Amp. If it is a concern you may want to find a stealth location elsewhere into the trunk, possibly behind or under the trunk molding (if the bottle will fit), or into the particle board covering the spare.

Once the brackets are in place simply screw everything together and you are ready to move on to the next step...
