The Art of Fabricating a Nitrous System: A DIY Guide

As I sat down to work on my nitrous system, I couldn't help but think that it was going to be a long and arduous process. With a budget of 300,000 dollars, I had high hopes for the performance boost this system would provide. But before we dive into the nitty-gritty details, let's set the stage.

I began by inspecting the fittings, making sure they were all in good condition. Obviously, no one checks these fittings beforehand, right? I mean, why bother when you're just going to use them anyway? So, I assumed everything was fine and went ahead with installing the system.

First things first, I needed to get the nozzle installed. Now, this was a crucial part of the system, as it would determine how much power my car would be getting. To avoid any potential issues, I decided to drill a hole in the plastic stock intake pipe that came with the system. It's not like the plastic is going to be strong enough or anything, but I figured it would be better to err on the side of caution.

I then force-threaded the nozzle into the hole I had drilled, hoping that it wouldn't come apart at any point in time. This was a pretty tight fit, and I could already imagine the nozzle popping out if nitrous backfired and blew its top. But I didn't let that stop me. With the nozzle installed, I could now proceed with installing the fuel line.

As I worked on the system, I realized that I needed to determine how much power my car would be getting from the nitrogen oxide (NOS) injectors. To do this, I had to choose the right Jets for both the fuel and nitrous systems. According to the instructions, a 75-100 shot fuel Jet should match up with a similar size NOS Jet.

Now that I had all my parts, it was time to get started on the installation process. First things first, I needed to install the fuel pump, which would provide the necessary pressure for the system to function properly. Next, I filled up the nitrous bottle and ran some wiring through the car's interior instead of leaving them dangling outside like a mess.

As I worked my way through the system, I couldn't help but think that this was going to be one long night. But with each passing minute, I grew more and more confident in my abilities. After all, how hard could it be to install a nitrous system? With the fuel pump installed, the nozzle screwed on tight, and the Jets chosen, I was finally ready to start testing out my new system.

I Hose-clamped the solenoids together and zip-tied them up to this bolt, which looked kind of Janky but would have to do. And with that, I had finally completed the installation process. Tomorrow, I would bring the bottle over to Brent's house and see if it all held up.

"WEBVTTKind: captionsLanguage: enwhat's up everyone as you guys know we bought this minivan a while back and we are planning to swap a different motor into it and boost it but for now I figured we could have some fun with this old motor and see how well it holds up to some nitrous so I got this nitrous bottle a while back from Brent and Hayden had these nitrous solenoids that he got from a guy that he's letting me use for this and I also got a 255 wal fuel pump because we're going to need a little more fuel for it got a momentary switch push button switch and then I also got the nozzle and this is going to be a wet kit so it's going to be spraying Nos and fuel at the same time and it should be pretty easy to install I already ran the line that goes to the bottle in the back it's just going through the firewall right now and all I got to do is hook up the switch to the solenoids run a fuel line to one of the solenoids and then run all that into this nozzle right here and then put that into the intake so I'm going to try to run either like a 75 or 100 shot on this thing see if it will hold and just try to have some fun with it it's already getting pretty late out right now so hopefully you can have this thing done by tonight and actually get to test it by tomorrow so I'm going to get started on it right now so I got both solenoids wired up I think it's right I just got one wire from each going together and then one side just goes to a ground and then the other goes to the positive on the battery but I found out that the switch I have is not a momentary switch it like stays on once you click it so you'll hear the solenoids go so right there they're on and if I don't hit the button again they stay on and I have to click it again to turn them off so I really don't want that I want to be able to push this down and then when I Let Go they're off again cuz right now they're on and then once I click it again you can hear them kind of turn off then they're off so I need to go pick up a new Switch or a new button so that they only stay on when I press it down and then when I let go they turn off and not have to click it again to shut them off like I can do it with this one if I just press it lightly and it works but I don't want that to stay on by accident so going to go get a new button real quick so we just got back in Charlie's wagon we went to Home Depot and a couple other local auto part stores but I didn't find any momentary push buttons that I liked they were all like a little too big and I wanted to find a red one because that's like typically what you would see for NOS so I'm pretty sure Brent has one so I'm just going to hold off until tomorrow and I'll just use this one for now it does work it's just hard to tell if it's on or off because right now it's on and that would be bad if I started up the car and just left it already on and it's just spraying gas and NOS constantly that probably isn't too good so I'm going to change that switch out tomorrow but for now I'm going to get the fuel rail pulled and tap off of that for the fuel line right here I'm just going to drill through it uh tap it out and I have a fitting that I can screw right into the fuel rail and then that will provide the solenoid with fuel and then after I get that done I'm going to be pulling off this black uh intake tube right here and either drill a hole into this and then put the nozzle wherever it went right here either put the nozzle into the stock plastic intake right there or drill a hole a little closer to the throttle body and go into the throttle body itself right here so I will see once I get that far but for now I'm going to get the fuel line ran and then I can also get the NOS line ran to this solenoid right here the bottle is empty by the way so I need to get that filled tomorrow as well and this has been on whole time and that solenoid was getting warm that's exactly why I do not like that push button at all so I'm going to get that fuel rail pulled off and get it tapped w so I just got the fuel rail put back on I got my fitting threaded into the rail and then I didn't leave much space I got a little too close to this uh throttle cable bracket but it fits so I've got everything tightened down and and I'm going to Prime the fuel pump right now and make sure nothing leaks and then I'm going to hit my button and make sure gas is coming out of the solenoid like it should so see if it works yeah and I got to grab my key to a box dude you and keys oh here it is I know I lose all my keys yes you do got too many TR see any leaks nope all right let me see this I'll hold it ready shoot on the ground let me start Prim it no prime it some more here watch I Didn't I'm just click it on and it's going to stay on now so I'm just going to prime it and see if it out of a bad idea but okay Pock it I mean whatever it's just fuel prime it again there you go who Jesus holy yes undo the Switch I'll prime it again and build a pressure in it might be able to see it better I don't know how well you can see it hold just let me plug the injectors in real quick and then I can start it cuz it don't look like there's any leaks did you check you checked all these fittings obviously no I did not actually you didn't double check them nope it is a bad idea I assumed they would be good here I'm just going to start it up and then you want to click the Switch right yeah we double check for it uh I mean nothing shot out of it so thing runs like diry hole Yeah it's 300,000 on it Jesus right spray it on Lucy you can make a flame thrower with this can you hear the car die yeah it's losing so much fuel W that's so much you might oh you might not even need the fuel pump I might you probably will though I might as well I yeah you don't have enough pressure it might mess it up everything on the fuel rail seems good nothing leaked and the solenoid fired like it should and I just got the intake tube pulled off the plastic stock one and right now I'm going to drill a hole in it right here and then probably just try to tap the nozzle in even though I should probably put a nut like on the back side to hold it cuz the plastic is not going to be strong enough but I think it should work I'm just going to make the hole pretty tight and then run the tap through it and pretty much just thread this into the plastic I mean it doesn't need to be perfect as long as it goes down in there and doesn't come out I'm not going to be too worried about it so I'm going to get a hole drilled right through here and then tap that out real quick so I just got the nozzle into the stock intake pipe I ended up just drilling a hole that was slightly smaller than the threads on that nozzle and then I just force threaded it in there this is more of like a rubber so it's not really a hard plastic so that guy just sunk right down in there and it's actually pretty tight like that's not going to be going anywhere unless this thing nitrous backfires and blows it apart which I won't really care if it does kind of hard to see but I got the nozzle pointing right at the throttle body so when I hit the button and it sprays the nitrous and fuel that will go straight into the intake which is what you want you don't want that nozzle like aiming against the way the air flow is going so that'll be a nice clear path straight into the intake manifold and now I can install this tube back onto the car and then hook up the nitrous and fuel line to the nozzle but before I hook the lines up to the nozzle I need to make sure that I have my Jets put in so these little guys right here are actually what determine how much power the car will be getting so these restrict the amount of Nos and fuel that go into the car and this is actually what determines like a 50 shot or a 75 shot or 100 shot it's all in this Jet right here so you need this or else you're going to blow up and right now I only have the one jet for the fuel so I can get the fuel line on but but I still need the jet for the nitrous and I need the jet that matches this fuel one right here they usually correspond with each other you want to have a certain size fuel jet with a certain size nitrous Jet and this jet I have right here for the fuel should be around a 75 to a 100 shot of fuel and nitrous once I get the other jet so it is quite a bit for this car it should be able to hold up and hopefully we don't blow it up right away but I guess we will find out but I can at least get the fuel line screwed on for now and then I'm just going to wait until I get the second jet tomorrow from Brent and then I will be able to screw my nitrous on once I get that so I'm going to get this tube back into the car and then get the fuel line screwed onto the nozzle well that's as far as I'm going to get on it tonight I just kind of Hose clamped the solenoids together and zip tied them up to this bolt looks kind of Jank but it will work I figured I should at least try to keep them off the motor cuz it gets pretty hot so tomorrow I still got to install the fuel pump go get the bottle filled up and then run the wiring inside the car instead of it hanging on the outside like that then get the last jet I need for the nitrous side on that nozzle and hook that line up and then hook the bottle up and bring it to Brent and see if it holds up and if it doesn't it's whatever it be funny to watch it blow up either way so I'm going to continue on this thing tomorrow and we'll see how far we get hopefully it all works outwhat's up everyone as you guys know we bought this minivan a while back and we are planning to swap a different motor into it and boost it but for now I figured we could have some fun with this old motor and see how well it holds up to some nitrous so I got this nitrous bottle a while back from Brent and Hayden had these nitrous solenoids that he got from a guy that he's letting me use for this and I also
