Ok so i was pointed into the direction of Nitrous and am thinking of doing that direction. I have a few questions though (sorry im a noob.)
Now i have never used it before and was looking on Summit and i was thinking of going with a Dry shot. But i got a little confused on some thing so here are my questions.

1-Whats the difference between microswitch and TPS? What are they and what would be best for a 1st timer like myself?

2-Do i want single or duel stage, also whats the difference and is one easier on the motor? I have no clue....

3-Also whats a good starter kit, ive heard Zex but i would like your opinion ( i noticed zex is the TPS style system.

4-What else would be good to have and/or recommended? I remember ryan saying something about a WOT or a Window Switch what should i get, and should i get anything else?
Also Ryan said something about a special spark plug wires, is there any other motor stuff i might need to replace?

Thanks a lot guys for this, sorry i know nothing about Nitrous But i appriciate the help! -The Novice.

A good starter kit would be the "NOS SNIPER KIT". Mirco switch is placed at the throttle cable so that you can position when the nos is engaged( best bet is at full throttle)And you need a different plug depending on how much nos you spray. Maybe someone else can help with the other ?. And maybe this answered some of them for ya. Good luck!

A dry system, preferably from NX. Single nozzle. WOT switch AND a window switch. Thats very important. A step colder plugs, and a timing light to keep an eye on timing. You can run your stock plugs wires... they'll be sufficient.

A good starter kit - Anderson Ford Motorsport/ Single Nozzle Nitrous system. Comes with a Series 4 PMS, and NX Nitrous system. Ive used it, and its fantastic. Cant go wrong with most dry systems.

Get a zex dry kit, it's got a Nitrous Management Unit that compensates for high or low bottle pressure and no other kit has that( bottle pressure is critical !!) , it's super easy to install, fool proof , and you just tap into the TPS so there's no rigging up a micro switch. i've used all kinds of nitrous kits over the past decade or so ( nitrous works, nos, zex , and IMO you can't go wrong with the zex dry kit )

So what is TPS then?

And Goblin for the window switch it sets what RPM's i can shoot at? Also is there any do's and donts about nitrous, ive seen videos of nitrous backfires and afterfires how do i avoid that kinda bad news for my engine stuff?

Lastly do these kits come with a "purge" kit set up already or do/should i buy something and whats a good kit? Thanks again guys, much appriciated!

[The Novice]

Oh sorry it wouldnt let me edit it, But my other question was do i want dual or single stage? and what does that mean, is one less ware on the engine?

[ryans88gt]

purge kits are nice to look at and might make a difference is you are doing some pro bracket racing, but otherwise they are just for show.

I said 1 step colder spark plugs, but it wouldn't hurt to have good wires and a good coil.

NX is my favorite brand of nitrous.

+1 to ryan and goblin, i'm also a big fan of NX, i'v never had problems, nor have i heard of any from them. a single stage is one shot of nitrous and a dual stage is for example when you shoot a 100 shot followed by a 300 shot (i'm pretty sure) so if i am right (i think i am) then you only want a single stage

tps is the throttle position sensor, basically with the zex kit you tap into 1 of the wires that go to the tps and it will turn the nitrous on at wide open throttle only ( which is the only time you use it ) and as far as nitrous backfires are concerned wet kits are far more succeptable to them then dry kits, as long as you stay off the rev limiter with the nitrous on ( even if you tag it once in a while you won't have any problems ) you'll be fine


On a side note, i've never used a window switch and i don't forsee me ever using one, the only benefit i can see from them is that they will cut off the nitrous before hitting the rev limiter but in my opinion if you are constantly running up against the limiter ( during burnouts, if you lose traction and don't let off the gas, or shifting after you hit it ) then you really need to invest in some driving lessons instead of a window switch

I thought you need/ want a purge kit so that ya can get the air out of the line so that you dont have a nitrous backfire or does that stuff not matter if your running a 100 or 125 shot? I was just wondering, sorry i know nothing. I plan to take her to the track once in a while when i get her going would it be a good idea or no. I could care less about LED lights. i actually though thats what caused backfires ( air in your lines )

Also i have 8mm Wires and the MSD blaster 2 coil. I accumre the coil is fine but should i upgrade the wires to 9mm or something?

Thanks for all the help guys! - The Novice.

[86_Notch]

nitrous backfires are the result in fuel puddling in the intake and being ignited ( no chance of that with a dry kit as the intake flows only air and nitrous ) a purge kit would be a nice accessory but by no means is it mandatory, i've only had 1 car with it and i usually wasted most of my nitrous scaring away the ricers in the hondas . my other 5 nitrous cars didn't have a purge and i was fine , as a matter of fact you would be better off buying a 255 fuel pump instead . put in the 125 shot make sure you back the timing up a few degrees and get a set of colder plugs and tighten up the gap .

Oh and i looked on summit at NX and they only have wet kits

Also 86 Notch i looked on Summit at the Zex kits and its says this for requirements = "Requirements: A vacuum ported fuel pressure regulator and a throttle position sensor (TPS) with a voltage output of at least 4.2 volt." So i was wondering does that mean i still have to buy this TPS thing or should my car already have this stuff on it?
Lastly 86 Notch said something along the lines that Zex has a computer that allowes you to only shoot at certian RPM's, but if this is my first nitrous kit and i wanna play it safe i would still want a WOT and a window switch, or does this zex computer take the place of the window switch?

Thanks for all the help guys! You've all been incredibly, so thanks you very very much! - The Novice.

[86_Notch]

your car has a tps, zex has a nmu which compensates for bottle pressure that's too high or too low, you don't need a window switch if you are a half decent driver

I have an intake 190 LPH pump i believe, but how would this help with nitrous? and do i need to upgrade to 255LPH too ?

Also i dunno if ya knew but im not poss. that i have forged internals (rebuilt motor) and to play it safe i want to assume no, other people told me i can still run Nitrous would you agree? And are there any other things i would need to to since i (might not) have all forged internals?

btw i have to run min. 91 octane fuel right?

[gotn20]

I have a nitrous works kit on mine and I love it. Try and get a throttle body plate kit. I think they do a great job of mixxing atomizing the fuel. I've only had one tiny fuel puddling issue and I run a 150 shot.

[86_Notch]

190 pump is fine, you don't need forged internals for a 125 shot, make sure you run premium gas to be safe

[The Novice]

yeah sadly we only have 91 grade around here But i assume thats good enough correct?
Is there anything else anyone recommends?

Oh also if i run nitrous and i was to get a gauge cluster should i get any for nitrous? (maybe not needed but recommended) Like air/fuel ratio or anything anyone can think of so that i can know everything is working ok and have some peace of mind.
Finally my car would be mostly street some strip, but on the street if some ricer is being a D-bag and wants to race me, i would look pritty dumb getting out of my car at a stop light getting out of my car, opening the hatch and turning on the bottle. So my question is can i keep it on/ open for long periods of time or is that just a really bad idea? or can i get some kind of switch like this? that activates it, then i push the button?

if ya have any other advice or recommendations i would love to hear them, as you can probably tell my now i know little to nothing about nitrous. Thanks ! - The Novice.

[2002BLGT]

run 9 degrees base timing , NOS or NX wet kit , run a 65 nitrous and 36 fuel jet with stock MAF , stock fuel pressure, 24 autolites gapped at .035 and 255 LPH intake pump and hold on for 7s in the eighth all day long as long as you can get a little traction with some good drag radials or ET streets

[Goblin]

You have the basic idea. A window switch allows the Nitrous to flow between a low preset RPM, and a high, preset maximum RPM. For example... 3000-7000rpm. Only between 3000rpm, and 7000rpm can the Nitrous be used. With a WOT- Wide Open Throttle switch, the Nitrous can only be activated at WOT, within the window of 3000-7000.

Its definately a good idea to invest money in both.

To prevent backfires, you should only ever spray Nitrous Oxide above 3000rpm. Stay out of the rev limiter (also helps to adjust the window to shut the Nitrous off before the rev limiter), just incase you miss a shift, and hit the rev limiter. Stay away from single nozzle wet systems if you plan to spray large amounts of Nitrous. In my experiences, ive lost alot of intakes and hoods because of single nozzle wet systems, and attempting to spray large doeses of the gas.

The most important rule to ALWAYS remember, is keep an eye on your plugs, and timing. Your plugs will never lie to you. Sometimes depending on conditions, timing may need to be adjusted, so keep a good check on timing. Start small, and work your way up. Need to walk before you run.

Ok thanks a lot! So just wondering i take its a bad idea to use nitrous in first gear huh? I though people at the track use it though gears but is it best to just use it in 5th?

Also i was looking at window switches and WOT abd i can only seem to find the window switches, some one ebay and stuff that they are 2-in-1. IS that possible/a good idea or BS?

Also what company brand do ya recommend for both any preferences? I saw MSD had some cheaper ones?

Finally usually how long will my plugs usually last? i dont plan on spraying too much, say 1-2 times a month for 4 months. And are there any signs that its time for new ones besides a fire under the hood?
