2005-2010 Mustang GT ZEX Wet Injected Nitrous System Review


The ZEX Wet Injected Nitro System is for 2005
to 2010 GTs, and it’s gonna be something that you should check out if you’re looking for
affordable horsepower gains, from an easy to install complete nitrous kit, that gives
you a range of 75 to 175 horsepower jets, for a stock or mildly modified car. This is designed to work with the stock fuel
rails and stock fuel system, so if you have a lot of modifications already, you should
consider a fuel pump upgrade, because you’ll wanna make sure that you aren’t starving engine
of fuel while spraying. And, if you wanna use those larger jets, you’ll
need to consider upgrading anyway, depending on your setup. A lot of people say that nitrous offers you
the best bang for your buck, if you’re looking for a big horsepower increase, and there are
a few different ways that you can go with nitrous. This particular kit comes with 75, 100, 125,
150, and 175 jets. It’s throttle position sensor activated and
it’s a wet system. This is a very comprehensive kit that comes
with everything that you’ll need for an easy, clean and straightforward install that’s well
done with no corners cut. I’m gonna call this install a two out of three
wrenches on the difficulty meter, because you do need some basic wiring knowledge to
get it done. You can plan on spending about a half a day
in the garage. Before you really look at this specific kit
further, I can start with a basic overview of a wet versus dry nitrous system, just so
you can make sure a wet system like this one is right for you. A wet nitrous system gets its fuel from a
connection to the engine’s fuel system, in this case, the stock fuel rail. The fuel spray is directly fed into the nitrous
nozzle. A dry nitrous system will inject enrichment
fuel or the extra fuel that you’re gonna need to burn the extra oxygen from the nitrous,
through the engine’s own fuel injectors, not the nitrous nozzle. So, looking at your jetting options right
away, since that’s one of the main concerns here, the kit is gonna include 75, 100, 125,
150 and 175 shot jets. So, you do have a few different options when
it comes to jets, but just know that you can’t go lower than a 75-shot with this kit. And keep in mind, that you might need some
other fuel components if you wanted to run those larger jets, but that’s all going to
come down to your set up and what your tuner set is. This kit does give you more jetting options
than others out there, but there is a nitrous outlet system that will give you a 200 horsepower
jet, if you really wanted to get crazy. One thing that’s different about this kit
is that it includes a nitrous management unit. So, the wet system connects to the fuel rail
system, and controls the amount of both fuel and nitrous through the management unit. ZEX does this because they say it helps to
control the fuel atomization, and ultimately, the power that you gain from the nitrous. What’s really nice about this is that the
major components of this kit, the solenoids, electronic throttle switch, etc., are contained
in one enclosure which makes for a plug-and-play install. This means you won’t need a mounting bracket,
or you won’t have to adjust the placement of your switch to make it work right, since
you won’t be using a throttle arm-activated micro switch. The way that this system works is through
active fuel control, that will automatically adjust the nitrous fuel enrichment with bottle
pressure. This helps keep things safe when you’re running
nitrous, and gives a little bit more engine protection. This system activates a wide open throttle,
so this system monitors the TPS voltage, to make sure that the nitrous is introduced at
the right time. You’ll have one wire that clips onto the TPS
output voltage wire. It will read the TPS voltage signal and send
it to a programmable electronics switch, that engages and disengages the system, based off
of a predetermined voltage special. And when talking about fuel atomization, this
system has an injector nozzle with a little bit different of a design. Two features of this nozzle are its fuel transfer
tube and the fact that it’s self-adjusting, in a sense. The fuel transfer tube injects the enrichment
fuel directly into the outer edge of the nitrous splint. The nitrous gas shears the fuel away from
the tube atomizing it to a finer degree than other designs have. This technique helps with fuel distribution
from cylinder to cylinder, and ultimately offers better engine protection. The transfer tube is also self-adjusting,
meaning that itself adjusts to the bottle pressure. The way that it works is that a vacuum is
created as the nitrous is sprayed across the tube opening. As the bottle pressure goes up, so does the
gas feed and vacuum level. The increase in vacuum pulls more fuel out
of the nozzle, which helps steer clear of going lean. Looking at the individual components, this
is a big kit, and I don’t have everything out on the table here, but it is gonna include
everything that you need to get this installed. This is a 10-pound bottle, but it will arrive
to you empty, just so you guys know. You’ll get your bottle clamps, the nitrous
nozzle, your hose assemblies, fuel jets, a wiring harness, all of your hardware and fittings
and your switch cover. Like I said earlier, this system is gonna
be used with the stock fuel rails, and it needs fuel pressure to be at 40 PSI. When it comes to price, you can expect to
pay close to the $600 mark for this. Like I mentioned earlier, a lot of people
consider nitrous to be one of the best bang for your buck modifications, when it comes
to return on investment. How else can you add over 100 horsepower like
this, while only spending $600? The flipside of that is that this isn’t a
consistent horsepower add. But either way, if you wanna compare the cost
of this kit to your other nitrous options out there, this kit is less expensive. The nitrous outlet kit is a little bit more
expensive, but it does offer up to a 200-shot if you’re looking for more than 175. And the other thing that I’ll tell you is
that you need to get a set of spark plugs. You’ll need one stock holder in order to run
the nitrous, just like if you’re adding a forced induction to your car. Install wise, this is a time-consuming install,
but it’s straightforward and not difficult as long as you can do some basic wiring. You can expect to spend about half a day in
the garage. And I’m gonna call this install a two out
of three wrenches on the difficulty meter. You’ll need a handful of different tools,
and of course, a wiring equipment so that you can wire this up. I’m gonna glaze over the details here just
to give you guys an idea since we aren’t showing you a full install, but there are step-by-step
instructions with the kit. You’ll need to decide where to put everything. Mount the nitrous bottle, mount the nitrous
delivery line under the car, mount the nitrous management unit, install the nitrous nozzle
and wire everything up for the instructions. Once that’s done, you’ll need to program the
activation switch, install the fuel delivery line, check both fuel and the nitrous pressure
lines, and check fuel quality and emission timing. Like I said, just a basic overview, but that’s
what you’re looking at install wise. That’s gonna cover things for the ZEX Wet
Injected Nitro System for the 2005 and 2006 GT Mustang. You can always check it out more online, and
for all things Mustang, keep it right here, at americanmuscle.com.
