      Video Review & Installation

      The Zex Wet Injected Nitrous System is for '86 to '04 V8's, and it's gonna be something that you should check out. If you are looking for affordable horse power hands from an easy to install complete nitrous kit that gives you a range of 75 to 125 horsepower jets for a stock or mildly modified car. This is designed to work with the stock fuel rails and the stock fuel system, so if you already have a lot of modifications you should really consider a fuel pump upgrade here because you are gonna wanna make sure that you are not gonna be starving your engine of fuel while you spraying.A lot of people say that nitrous offers you the best bang for your buck. If you are looking for a big horsepower increase there are a few different ways you can go with nitrous. This particular kit comes with 75, 100 and 125 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 are gonna need for an easy, clean, and straight forward install that's well done with no corners cut. Gonna call this install a two out of three wrench in the difficulty meter since you do need some basic wiring knowledge to get it done. You can plan on spending about half a day in the garage.Before we really look at the specific kit further, I can start with a basic overview of a wet versus dry nitrous system just so you can make sure that a wet system like this one is gonna be the right choice for you. A wet nitrous system gets its fuel from a connection to the engines fuel system, in this case, it's gonna be the stock fuel rail. The fuel supply is directly fed to the nitrous nozzle. Now a dry nitrous system, on the other hand, injects the enrichment fuel or the additional fuel that you are gonna need to burn the extra oxygen that the nitrous is gonna give you through the engines own fuel injectors, not the nitrous nozzle. So looking at your jetting options right away with these kits since that's one of the main concerns here. This kit is gonna include 75 100 and 125 shot jets so you do a few different options when it comes to the jets but just so you know you can't go any lower than a 75 shot with this kit.Now if you are actually looking for something a little more than a 125 shot there are some other options like either of the nitrous express kits. Those options are gonna give you a 150 shot option. One thing that is different about this kit is that it includes a nitrous management unit. So the wet system connects to the fuel system and controls the amount of both fuel and nitrous through the management unit. Zex does this because they say that it helps to control the fuel atomization and ultimately the power that you are gonna gain. What's really nice about this is that the major components of this kit like the solenoid and the electronic throttle switch are contained in one enclosure which makes for a plug and play install. This means that you won't need a mounting bracket or you won't have to adjust the placement of your switch in order 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 to the nitrous fuel enrichment with bottle pressure. This is gonna help keep things safe when you are running nitrous and it's gonna give a little more engine protection.Now this system activates at wide open throttle, so the system is going to monitor the TPS voltage to make sure the nitrous is going to be introduced at the right time. You will have one wire that clips on to the TPS output voltage wire, and this is gonna read your TPS voltage signal and send it to a programmable electronic switch that then engages and disengages the system based off a predetermined voltage threshold. And when talking about fuel atomization, this system has an injector nozzle with a little bit of a different 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 plume. The nitrous gas shields the fuel away from the tube atomizing it into a finer degree than other designs can. This technology helps with fuel distribution from cylinder to cylinder and ultimately offers a better engine protection. The transfer tube is also self-adjusting and meaning that it self-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 speed and the vacuum level. The increase in vacuum pulls more fuel out of the nozzle which then helps to steer clear of going lean. Looking at the individual components of this kit, this is a big kit but it's gonna include everything that you need to get this installed. It's a 10-pound bottle but it will arrive to you emptied just so you guys know. You get your bottle clamps, the nitrous nozzle, your horse assemblies, fuel jets, a wiring harness, all of your hardware and fittings, and your switch cover.Like I said earlier this is system is 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 play close to the $600 mark for this. 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 while only spending $600? Now the flip side of that is that it isn't a constant horsepower add but either way if you wanna compare the cost of this kit to your other options out there, this kit is less expensive. The nitrous express kits are a little bit more expensive but they do offer up to 150 shot if you are looking for a more than 125. Install wise this is a time-consuming instal but it's straight forward and not difficult as long as you can do some basic wiring. You will expect to spend about a half a day in the garage. I'm gonna call this a two out of three wrench in the difficulty meter. You are gonna need a handful of different tools and of course, wiring equipment as well so you can wire this up.I am gonna glaze over the details here just to give you guys an idea since we aren't going to show you guys a full instal, but there are step by step instructions that are gonna come with the kit. You will need to decide where to put everything. Mount the nitrous bottle, mount the nitrous delivery line under the car, mount the nitrous management unit, instal the nitrous nozzle, and wire everything up per the instructions. Once that is done you will need to program the activation switch, install the fuel delivery line, check both the fuel and the pressure lines, and check the fuel quality and ignition timing. Like I said it's just a basic overview, but that's what you are looking at instal wise. That's gonna wrap things up for the Zex Wet Injected Nitrous System for the '86 to '04 V8, and as always you can check out more online right here at americanmuscle.com.

      Description

      Gain Up to 125HP. ZEX Wet Injected Nitrous Systems include 75, 100, and 125 shot jets that will get your Pony flying down the track faster than you ever thought possible for less money than you'd believe. It doesn't get cheaper to add that much power to your Mustang.

      Advanced Electronic Control. ZEX's Wet Injected Nitrous system uses patented "Active Fuel Control" that automatically adjusts nitrous fuel enrichment with bottle pressure. The result is that your engine never runs too rich or too lean, preventing engine damage. Unlike other less expensive systems, the ZEX "Wet" nitrous systems activate at wide-open throttle using advanced electronics that monitor your engine's throttle position sensor voltage to ensure activation at precisely the right time. This makes using your nitrous system very easy and reliable.

      Better Nitrous Delivery. Unlike "dry" nitrous systems which inject nitrous directly, ZEX Wet Nitrous Systems connect to your fuel system and controls the amounts of fuel and nitrous using their management unit. The result is better control, complete fuel atomization, and more power.

      Application. This Zex Wet Injected Nitrous is designed for use on the 1986-2004 5.0 and 4.6 V8 Mustangs with the stock fuel rails. System requires a minimum fuel pressure of 40 PSI.

      Technical Notes. Professional Installation recommended. Requires fuel pressure of 40 PSI.
