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
