for dry kit set up you'll wanna have a few
components available to help you select an installation point for your fan spray
nozzle you should do a hand threaded assembly of
both nitrous solenoids with their connection tee fitting
and install the mounting bracket at the extension fitting for the nitrous
pressure regulator along with its hose barb next screw the
nitrous filter into the initial solenoid then thread in the feed line that travels
from the secondary solenoid to the nozzle along with the tuning jet now you'll have a
temporary plumbing assembly that will help you determine a number of
variable mounting options place the temporary plumbing Assembly under the
hood and look around for the best point to
introduce the nitrous into your engine the nozzle and hose will most likely need
to be inserted sideways rather than straight down because of
hood clearance issues with the hose protruding from the nozzle locate the throttle body it's the unit
where the main air intake tube enters the engine it has
an actuation lever that controls the throttle plate inside the nozzle needs to be positioned just
upstream of your throttle body but can not be upstream of a mask air flow
sensor finding a good location between the air
cleaner and the throttle body anywhere about six to 12 inches ahead of
the throttle body opening is best for most installs you also have the option drilling into
the throttle body opening itself as long as the throttle plate operation
isn't interfered with drilling into an intake tube is another
popular option another final option is using your stock
plastic or rubber intake duct along with the nozzle mounting collar
and it's nut that's included in your kit while you're
here with the temporary plumbing assembly consider the placement of the solenoids
and the routing of the nitrous line from the bottle also
think about the vacuum line that will travel from the nitrous
regulator to the stock engine fuel pressure regulator once you've
picked an entry point for the nozzle check that the feed line routing allows
you to mount the solenoid bracket to a convenient place look for an existing bolt or if it works
better consider adding a bold and/or adapter bracket to an unused per-threaded hole in the
engine also remember you can change the orientation
of the nitrous pressure regulator if needed the regulator can be positioned straight
down perpendicular to the solenoids or straight up and between the solenoids
now that you found a good spot for the nozzle and solenoid bracket we can get to the actual installation of
the nozzle if you're going to drill into the throttle body opening you
actually be drilling through the clamp the end of the intake
tube and the throttle body opening itself to get the most secure fit for the
nozzle you'll need to start by removing the intake tube and then stuff a piece of rag or paper
towel up against the closed throttle plate you can tape the edges to help keep
shavings out at the intake and throttle body interior also stop a large piece of rag into the
intake tube to catch any debris from falling
toward the air filter now replace the intake tube and it's hose
clamp and tighten the assembly so the tube is in its final install
position mark the drilling point on the clamp or
the intake tube if you have a split clamp like this and with the quarter inch drill bit make
a nice clean hole all the way through into the throttle body
opening now pull off the intake tube and clamp leave the throttle body opening plugged
and using the thread tap that was included in your kit add threads to the hole in the throttle
body opening be aware you may need to remove a couple nearby
components in order to get a full spin out of the tap wrench next use a five
sixteenths inch bit to enlarge the holes in the clamp and the
inlet duct make sure your new threads are clean and
DeBoer any outer or inner edges with some fine
grit sandpaper use a vacuum and/or pressurized air to
clear away all the metal and plastic shavings from
inside the throttle body and inside the inlet duct interior
remove all tape plugs or rags and make sure that no
debris was caught in any interior ridge's of the intake tube
now you can reassemble the intake duct be sure to reset the alignment of the
holes as you tighten the clamp there is an alternate method for nozzle
mounting if you don't want to drill into your throttle body there's a nozzle mounting collar and nut
that was included in your kit for installing the nozzle
into the stock inlet duct or an aftermarket intake tube as you
decide on an entry point for the nozzle keep in mind that you need hand access
to the interior drilling point to install the mounting collar from inside the duct and will also need
to hold the collar steady with a tool while you tighten the nut from the
outside with that said drill a seven sixteenths inch hole into the inlet duct while it's removed
from the vehicle clean out any shavings with air or vacuum and make sure the edges are smooth as we
described install the collar from the interior of the tube add some
teflon paste or a paste type sealer to the collar here
now from the inside hold the collar with the tool while you
tighten the nut from the outside at this point make sure your entire
intake assembly has been reassembled and tightened
properly so we can install the nozzle to its new home the nozzle will thread in the place and needs
two things for a proper install the first is to mark the exposed area
of the nozzle that should face forward before
installing look at the exit direction of the nitrous from the
nozzle and directly above it edge a mark in the exposed area of the
nozzle so that as you thread it in you'll know where to set
the final pointing direction of the spray the second thing you need
to do is seal the threads of the nozzle do not use teflon tape to seal the
threads pieces can break off and enter your intake stream potentially
causing severe engine damage so use a teflon paste or a plumbing pipe
thread sealant that contains PTFE which is a teflon
derivative with a thin even amount of sealant on
the threads spin the nozzle into either the threads
you created in the throttle body or the mounting collar that you
installed in your intake duct or tube don't let the nozzle bottom out
in the threads when spinning the nozzle in by hand if
its seats and stops turning just spin the nozzle slightly backwards
until the mark that you made on the nozzle points directly towards the throttle
body of the engine the nozzle should feel secure but remember the teflon paste needs a
bit of time to solidify
