What Is Nitrous Oxide?
Nitrous oxide is a gas composed of two
nitrogen atoms bonded to one oxygen atom.
The scientific abbreviation for one nitrous
oxide molecule is N2O where N is nitrogen,
and O is oxygen. This is where the familiar
phrase 'N-2-O' comes from when people talk
about nitrous oxide.
How Nitrous Oxide Makes Power
Nitrous oxide kits make large amounts of
horsepower by allowing an engine to burn
more fuel. Burning more fuel creates higher
cylinder pressures that will push down on the
pistons with greater force. When the nitrous is
injected into an engine and the initial
combustion takes place, it creates enough heat
to separate the nitrous oxide into its two
components, nitrogen and oxygen. Once
separated, the additional oxygen is then free to
react with additional fuel.
To run nitrous successfully and safely, you have to introduce precise amounts of additional fuel
with precise amounts of nitrous oxide. All of the extra oxygen provided by the nitrous oxide
must have fuel with which to react or you may damage your engine severely. When the amount
of nitrous and the amount of supplemental fuel are controlled precisely, your engine can safely
and reliably generate exceptional power increases.
Wet & Dry Nitrous Systems
A fuel injected dry manifold system uses a spray nozzle to deliver only nitrous oxide to the
intake. A wet manifold system introduces fuel and nitrous into the intake manifold. With a dry
manifold system, the additional fuel is supplied by increasing fuel delivery from the injectors
when the nitrous system is activated. It is called a dry manifold system because there isn't any
fuel present in the intake manifold. The ZEX™ Nitrous System is a dry system.
Powerful Features, Plus it's Easy to Use and Easy to Install
The ZEX Nitrous Oxide System automatically adjusts the amount of enrichment fuel in relation
to the nitrous bottle pressure, thereby maintaining consistent nitrous to fuel ratios. The result is
greater power and reliability at all bottle pressures. Our solenoid is more efficient and require far
less current draw than our competitor’s kits. This reduces the chances of burnt wires, blown
fuses, etc. from excessive solenoid current draw. Once armed, the ZEX™ Nitrous system is
engaged at wide open throttle by an electronic switch that uses the engine's throttle position
sensor (TPS) circuit. Wiring the switch is easy-just tap the kit's white wire into the TPS voltage

output. Simple and reliable! It's easy to install, with all the major components (solenoid,
electronic throttle switch, and nitrous manifold) contained in an attractive enclosure with a preassembled
wiring harness. It's a "plug and play" installation!
Why Our Nitrous System Is Better?
What makes our dry manifold nitrous system work so well is that the fuel control circuit
references the actual bottle pressure to determine enrichment fuel needs. The other kits on the
market use fuel regulating systems that ignore bottle pressure entirely, thus producing a constant
level of fuel enrichment no matter how much nitrous is really going into the engine. Ours, in
contrast, is self adjusting within its operating range. This difference in approach allows our kit to
have optimum nitrous to fuel ratios at all bottle pressures. That is how we can give you more
horsepower per pound of nitrous and less chance of engine destroying detonation.
Even our method of system engagement is better. Most current nitrous systems use a throttle arm
actuated micro-switch. That means you have to fabricate a mounting bracket for the switch and
adjust the placement of the switch to make it work right. Our nitrous kit utilizes a wire that you
simply clip on the throttle position sensor (TPS) output voltage wire. The TPS voltage signal is
sent to a programmable electronic switch that engages and disengages the system at a
predetermined voltage threshold. Above the threshold determined for wide open throttle, the
system activates. Below the voltage threshold, it remains dormant.
How The ZEX Nitrous Oxide System Works
The ZEX™ Nitrous oxide injection kit begins with a supply cylinder containing pressurized
liquid nitrous oxide. This cylinder is connected by means of a delivery hose to a normally closed
electric solenoid valve. This solenoid valve, which is attached to a manifold assembly, is
engaged and disengaged via the TPS switch. The manifold assembly distributes the nitrous oxide
to the engine's air inlet and the kit's supplemental fuel control circuit. The nitrous oxide that is
delivered to the engine's air inlet is conveyed via a delivery hose to an injection nozzle. The
amount of nitrous oxide, which provides the oxygen required for the horsepower increase, is
adjustable by means of a metering jet installed in the injection nozzle itself. The nitrous oxide
that is distributed to the fuel control circuit passes through a small bleed orifice. This bleed
orifice provides a reference source of bottle pressure and a controllable source of pressure to
perform the needed function of fuel enrichment. Fuel enrichment occurs by conveying this
source of pressure through a delivery hose to the vacuum port on the fuel pressure regulator. This
source of pressure on the rubber diaphragm of the fuel pressure regulator causes an increase in
fuel pressure. This increase in fuel pressure performs the function of adding fuel volume through
the engine's own injectors. The amount of additional fuel that is added can be changed by an
adjustable metering jet in the fuel control circuit. This jet accomplishes the task by controlling
the amount of pressure allowed to build in the delivery hose to the fuel pressure regulator. The
jet bleeds off excess pressure in the fuel control circuit and vents it through a delivery tube, back
to the intake manifold plenum.

How to Adjust Power Levels
The ZEX™ Nitrous kit is designed for multiple
power levels. These levels are controlled by metering
jets installed in the nitrous nozzle and fuel jet holder.
To change the power output, all you need to do is
install the appropriate set of jets as shown in FIG.1.
The correct combination of jets is listed on the tuneup
sheet on the back of this instruction manual.
Quick Start Reference Guide
Work Safely: Always wear eye protection and gloves when working with lines or hoses that
contain pressurized nitrous oxide or fuel. Never transport nitrous cylinders loose in a trunk or the
back of a pick-up truck and especially NOT within a vehicle's interior whether the cylinder is full
OR empty. Always disconnect the GROUND side of the battery when working on any electrical
components.
Nitrous Oxide won't fix problems you already have: Before you install your nitrous system,
be sure your engine is in good mechanical condition. Intermittent wiring problems, etc., can lead
to erratic system performance and possible engine damage.
Never defeat the operation of the
safety relief disc in the nitrous
cylinder's valve stem: It's required by
law and is there for your safety. Never
drill, machine, weld, deform, scratch,
drop, or modify a nitrous oxide tank in
ANY way whatsoever!
Never overfill nitrous cylinders:
That little bit extra will put you and
others at risk of injury. More often
than not, when the cylinder warms up,
the pressure goes above the limit of the safety relief disc and you lose all the nitrous you just
paid for.
All the power comes from the fuel, not the nitrous: Nitrous oxide is simply a tool that allows
you to adjust how much and how quickly the engine burns the fuel. If the fuel isn't there, the
power won't be either.
Avoid detonation at all times: Nitrous enhanced detonation is much more damaging than
detonation that occurs when naturally-aspirated due to the increased amount of fuel available for
releasing energy and the fact that more oxygen is present.
If, when your system is activated, something doesn't feel or sound right, BACK OFF: If you
hear any detonation or feel anything unusual, get off the throttle. It's a lot easier to check
everything over than it is to just try to drive through it and damage expensive parts. Don't

activate or have the system activated when you hit the stock rev limiter. The stock rev limiter is a
fuel cutoff. If you cut fuel while you're injecting nitrous, you're instantly very lean. This
momentary lean condition has the potential of causing engine damage.
Engine Modifications: The ZEX™ Nitrous System, out of the box, is designed to work as a
bolt-on kit for stock or mildly modified vehicles. Mildly modified vehicles would include
header upgrades, exhaust upgrades, air filter kits, etc. If major engine modifications have been
performed, larger injectors and a fuel pump upgrade will be required for safe nitrous system
operation. Major engine modifications would include turbochargers, superchargers, aftermarket
cylinder heads, head porting, camshafts, intake manifolds, etc. Failure to upgrade the fuel
system when using nitrous in these highly modified applications may cause serious lean
conditions that can result in severe engine damage.
Spark Plugs & Nitrous Performance: Quite often, a
factory type wide-gap projected nose plug will produce
a detonation condition after a few seconds of nitrous
use. The detonation is not due to the heat range, it
occurs because the ground strap of the spark plug
becomes a glow plug instead of a spark plug. The
ground strap is too long to dissipate the extra heat
produced by a nitrous accelerated burn. The correct
solution is to replace the plugs with units that have shorter ground straps. By doing this, you will
shorten the heat path from the ground strap to the plug base. ZEX™ Hyperformance™ spark
plugs are recommended for many applications.
Reading Plugs & Tuning ZEX Nitrous Kit: If you've installed larger injectors or have
otherwise increased the capacity of your fuel system, you need to read the following. Because
the real limit of how much power you make with the ZEX™ Nitrous Kit is your car's fuel
system, you need to tune up to that limit. Start with the lowest power level nitrous jet and
corresponding fuel metering jet. Make a full throttle pass at the drag strip and read the plugs. Not
enough nitrous/too much fuel results in a sooty, black plug coloration. This coloration means that
the fuel mixture is too rich. Too much nitrous will exhibit high heat in the form of a bluish or
rainbow-like coloring on the plug's metal surfaces. This means you're engine is about to, or is,
detonating. If this is observed, ensure the proper spark plugs are installed, reduce nitrous/increase
fuel delivery, and ensure the proper grade of fuel is being used. When you check the spark plugs,
check EVERY plug. Don't just spot check the easiest plug you can access. Due to the wide
possibility of air/fuel mixture variations, you need to check every single plug for signs of
detonation or other problems. If your plugs indicate too much fuel, trim the fuel delivery down
by installing a larger metering jet. If you are too lean/not enough fuel, you need to install a
smaller metering jet to increase fuel delivery.
Clear Nitrous Lines After Use: Close bottle valve. Use purge kit to relieve line pressure or
open line fitting to let nitrous bleed off.

Installation Instructions
Step 1: Decide Where to Put Everything
Before you drill a hole in your car, make sure you know where you're going to install the various
components of this kit. You'll have to discover the best positions for each component by trial and
error. First, the nitrous line that attaches to the engine air intake is about 2-feet long. That means
where you choose to install the nitrous nozzle decides, within a
2-foot radius, where you have to mount the Nitrous Management
Unit. Also, you need to connect the vacuum/pressure circuit for
the fuel pressure regulator to the Nitrous Management Unit, so
be aware of the distance between these components.
You'll also have to decide where to install the arming switch and
nitrous bottle. The arming switch should be installed in a
positioned convenient to the driver, but not in an area that
increases the chance of unintentionally arming the system. You'll
have to run a wire through the firewall to the Nitrous
Management Unit. Do it just like you would run a lead for your
stereo system. In fact, if you have one installed, you can probably
run the arming lead through the same grommet. If not, try to use a
wire loom hole that is grommeted. To help decide where you'll
mount the nitrous supply bottle, check the following section for
technical restrictions on bottle mounting locations and positions.
Step 2: Mount Nitrous Supply Bottle
Mount the nitrous supply bottle so that it is separated from the
passenger cabin. Fastback style cars that do not have separate trunk
compartments have to be equipped with a safety blowdown tube.
Route the tube from the safety pressure relief cap to the exterior of
the car, preferably under the car. Doing so will prevent your car
from filling with a cloud of nitrous oxide should the safety pressure
relief cap rupture.
Index the pickup tube with bottle position. (Refer to fig's A, B, and
C). ZEX™ nitrous bottles are designed with the bottom of the
siphon tube at the bottom of the bottle towards the outlet. Always
mount the bottle so that as your car accelerates, the liquid flows
toward the pickup tube.
Step 3: Mount Nitrous Delivery Line Under The Car
When routing the nitrous delivery line under the car, try to use the
subframe as a conduit. This protects the line and eliminates the
need to use clamps. The supplied cable ties work if you can run the
line higher in the under-body so that it's safe from road level
obstacles such as speed bumps. For the pro-race look, you can use
steel loom clamps with rubber sheathing to fasten the line to the
body.

http://www.zex.com
Step 4: Mount Nitrous Management Unit
Keeping in mind the length restrictions of the nitrous nozzle feed line and hose connections,
mount the Nitrous Management Unit in a suitable location. Use the four screw holes provided for
this purpose. It's a pretty rugged piece of equipment that is built to withstand underhood
temperatures as well as exposure to weather.
Step 5: Install Nitrous Nozzle
Optimum nozzle placement is 6" to 18" from the throttle body.
After you have determined where to mount the nitrous nozzle
(Fig. F) in the intake, make sure this location won't interfere
with other components. If your engine uses a mass air flow
sensor, mount the nozzle after the sensor, but before the throttle
body. After you've found the spot, mark it and remove the
rubber air inlet duct from your engine. Drill a 7/16-inch (.4375)
mounting hole and install the bulk head fitting. Be sure to
remove any drill shavings since they can severely damage your
engine. Install the nitrous nozzle so that the spray is in the direction of airflow.
We've enclosed a tap (Fig. F) should you need to
mount the nozzle in a metal duct. Just drill a 1/4
(.250)-inch hole where you want to mount the
nozzle, tap the hole and install the nozzle. Once the
nozzle is installed, place the appropriate tuning jet
in the nozzle and tighten the 2-foot long, -3AN hose
over the nozzle end (Fig.G).
Step 6: Install Regulator & Intake Hoses
Measure & cut to length the two hoses that lead
from the Nitrous Management Unit's regulator and
intake hose barbs. The regulator hose barb from the
Nitrous Management Unit gets connected
to the vacuum fitting on the engine's fuel
pressure regulator with one of the lengths
of hose. The intake hose barb from the
Nitrous Management Unit gets connected
to an unused vacuum fitting coming off
of the intake manifold plenum with the
other length of hose. Install the fuel
tuning jet in the holder as seen in Fig. G
and tighten the hose barb / tube nut
assembly over the top of the jet.
Step 7: Wire It
Once you have mounted the components,
you are ready to wire the nitrous system.
From the Nitrous Management Unit, find
a suitable ground for the black wire and

connect to it with the included crimp-on ground ring. Run the red wire through the firewall of the
vehicle into the interior, behind the dashboard. Ensure that the red wire passes through a
grommeted hole and not a bare metal hole. The wire's insulation may be rubbed off if put
through a non-grommeted hole. Run the white wire from the Nitrous Management Unit to the
output voltage lead from the throttle position sensor. After those connections are completed, you
need to install the arming switch/wire harness assembly. Find a suitable place in the interior of
the vehicle for the arming switch and drill a 1/2 inch (.500) hole. Mount the switch and switch
cover through this hole. Take the lead that the fuse assembly is attached to and find a suitable 12
volt accessory source of power under the dash. Use the T-tap electrical connector to splice into
the 12 volt accessory wire and plug in the wire harness lead. Take the other lead from the arming
switch and connect it to the red wire from the Nitrous Management Unit. As a reference for wire
locations, use Fig. D.
STEP 8: Program Activation Switch & Check Vacuum and Pressure Lines
Now that you have completed the installation and wiring of your nitrous kit, one of the final
steps is to program the Activation Switch and check the vacuum and pressure lines. To program
the Activation Switch, turn the vehicle's ignition on, but do not start the engine. Turn the nitrous
arming switch to the "ON" position. Go to the Nitrous Management Unit (NMU) and locate the
push-button switch. Depress, then release, the push-button switch. Observe the NMU's
Operation Light. At this point, it should be RED. This RED light informs you that the NMU's
Activation Switch is in learn mode. Return to the driver's seat and depress the accelerator pedal
to the floor, holding it there for ten seconds. Release the accelerator pedal and go back to the
NMU and observe the Operation Light. At this point, the light should be flashing continuously
from RED to GREEN to OFF. This is the NMU's way of telling you that it has successfully
learned the voltage curve of your engine's throttle position sensor. Go back to the driver's
compartment and turn off the system's arming switch, then turn it back on. Go back to the NMU
and observe the Operation Light. It should be solid GREEN at this point. This informs you that
the system is armed and ready to activate at wide-open throttle. Return to the driver’s seat and
depress and release the accelerator pedal several times. You should hear the solenoid click each
time you reach wide-open throttle. At this point, your Activation Switch is fully programmed
and ready for use. If you ever transfer your nitrous system to another vehicle, perform this same
procedure on the new vehicle to "relearn" the NMU's Activation Switch.
To ensure that the system is ready to be used, a final vacuum and pressure check of the system's
hoses and lines must be done. With the engine running, check your "intake" and "regulator"
hoses for any vacuum leaks. Generally a vacuum leak will cause the engine to run rough.
Assuming the vacuum lines check out, open the nitrous bottle valve. Listen carefully to your
engine as the valve is opened. You should not hear a difference in idle speed or engine sound. If
you notice either of these changes, call the ZEX™ product support line.
If there is no change in idle speed or engine sound, shut the engine off at this time and inspect
the nitrous pressure lines and fittings for leaks. Leaks in the nitrous supply line will be obvious
because they will be covered with frost.
STEP 9: Check Fuel Quality & Ignition Timing
The last thing to do before enjoying your new nitrous system is to ensure that premium fuel (92
R/M Octane or better) is in the fuel tank and that your ignition timing is set correctly. All
ZEX™ * 3418 Democrat Rd. * Memphis, TN

http://www.zex.com
recommended ignition timing retard amounts, on the Tune-Up Sheet, are calculated off of the
base, stock ignition setting. It is important to set this with a timing gun before you use your
nitrous system for the first time. Do not assume that it is set properly. If the ignition timing is
not set correctly, severe engine damage may occur.

the NOS brand has the little solenoid things and thas what were having trouble eith

amy

i would check their website then...

Soccerking3000

ok here is the quick and dirty, you have one solenoid with a power and a ground going to it, those need to be attached to a relay and then the relay is also attached to your WOT switch which will be in series with the arming switch you put inside the cabin. From there just attach the main nitrous line to the nozzle and the bottle and you're goodto go.

I however would HIGHLY suggest getting a wet kit so you have some way of adding fuel as well as nitrous.

hmm it seems like it would go between the fpr and the manifold to raise the fuel pressure when you are spraying so you have mroe fuel, but i'm not sure the picture is too small

thats what my homie thought.. but still not sure

ill take some pics of it give me a sec

the dry kit adds fuel.

Hence why you intercept the Vaccum line on the FPR. When the nitrous is activated and spraying, it adds less vaccum on the FPR to generate more fuel pressure. If it had no way of adding fuel, it would blow up instantly.

yea but thats no way a reliable way to use nitrous...
