2.6 Nozzle Installation (Continuation)...
7. Using liquid Teflon, install the nozzle into the mounting collar.
8. Be sure the nozzle discharge is facing towards the throttle body.
9. Install the correct jets into the fuel and nitrous inlet fittings of the nozzle. Please refer to the
Section 1.2 Jet
Map Information
to determine the correct nitrous and fuel jets to install into the nozzle.
10. Install the 3AN lines from the solenoid outlet fittings to their corresponding spray nozzle jet fittings and tighten
securely.
11. Install the intake boot.
Shown above is the E1 nitrous nozzle that is supplied with your
kit showing the correct jets being installed in the fittings.
Nitrous and fuel jets are similar in appearance except for their
orifice sizes which are stamped on the jet body. When
installing the nitrous and fuel jets supplied with your system,
be certain that you are installing the correct jet in the correct
nozzle inlet. By installing the incorrect
jets into the nozzle
inlets, severe engine damage will occur
.
Please refer to
Section 1.2 Jet Map Information
for the correct jets to
install in your nozzle.
Shown above is the correct and incorrect nozzle depth. Be
certain that the nozzle protrudes as shown to prevent severe
engine damage. If the nozzle does not protrude far enough,
the fuel outlet will be blocked, causing an extreme lean
condition in the engine which would cause a catastrophic
engine failure. If the depth is incorrect, use a 1/8”-27 NPT
tap to acheive the correct depth.

Nozzle should be placed in the intake boot so as to have a clear path
to the throttle body. Try to keep the nozzle from having to travel
through any bends that may be in the intake boot and as close to
the throttle body as possible. Shown above is an installed collar and
nut in the stock intake boot of a Honda Civic.
*Note: Some aftermarket intakes utilize aluminum tubing to
replace the stock rubber boot. In such cases, the collar and
nut may create a vacuum leak, and the tubing wall may be
too thin to tap and thread the nozzle directly into the intake
boot. In these cases, use Edelbrock Nozzle Installation
Bungs (Cat. #72555).
