Default Just bought nitrous outlet kit. What else do I need?

I just bought the brand x nitrous outlet kit.. What else will I need? It's for my 1999 z28 with full bolt-ons.. So what plugs will I need? I am wanting to get the lengenfelter timing retard box for the timing. What else will be needed?

depends what all the kit came with,

I would recommend a WOT switch, window switch and a bottle warmer and purge if it did not come with those, the purge is not a big deal but the other 3 are very much needed

you wont need injectors since its a wet kit but I would greatly recommend a upgraded fuel pump

and by the looks of the pic it didnt come iwth any of it looks like a basic kit, I would recommend getting a plate instead of tapping into your intake piping

A plate is nice but a waisted chunk of money on a basic kit. You already have a nozzle and clearly are looking for low cost.

The kit says it comes with a WOT switch. The window switch I don't know if I will get or not. I think the window switch is to get the nitrous to spray at a certain rpm range and shut down between shifts right? I would rather just set it up to when I flip a switch the nitrous sprays and I just won't spray it off the line or until I'm at 3k rpm. I really am wanting to get a bottle heater though. This looks like money well spent to me so you can get more out of your bottle right?

So here is where I'm at. Planning to get br7ef's plugs, lengenfelter timing puller, and a bottle heater. Now what I have left to worry about is where I want to install my WOT switch. I wanna make it to where I can just push a button when I want the nitrous.

Then you don't need a WOT switch. Just put it on a button in the car.

The WOT switch should be the little black micro switch with the metal tang coming out of it. Most people put that under the hood near the T/B and when the pedal is pressed to the floor a part on the T/b will contact the micro switch and activate the nitrous.

I play on the street so I don't use that. The same wiring that goes to the switch I bring it inside the car so I can spray when I want. I can spray out the hole or just use it to hold someone off by a car length to take their money.

Usually a WOT switch and window switch go hand in hand, basicly with that setup your nitrouse will only spray at WOT and between whatever RPM range you set the pills at.

there are basicly safety features to prevent blowing your motor on n20, hitting the n20 at low rpms or when not at full throttle can cause detonation and destroy your motor.

there not required but are just safety items and also keep your n20 runs consistant in the 1/4 and prevent the nitrouse spraying at to high rpms also. they are ususaly wired to a activation switch and when the switch is on you dont have to push any buttons it leaves your hands free to shift and steer the car and will activate when under WOT and in the rpm range.

you could just wire it on a activation switch and a button so that you can control the n20 with the push of a button. its not as safe but thats how it has been done for a VERY long time with the old school guys.

a bottle warmer is also a very good idea, it does quit a few things, not only does it make your n20 last longer it also keeps it consistant, the more empty your tank gets the less pressure you get and the less n2o gets sprayed each time the pressure drops thus changing your n2o fuel ratio which is not a good thing. the warmer will maintain the pressure until the bottle is empty by heating it to expand the gas more.

oh and to answer your question about plugs, stay away from plugs that have exposed rods, get plugs that have them inset into the plug. ususally 1 step colder helps some as well

you dont really need a tune but i would atleast get my air fuel ratio checked on a dyno under the n20 just to make sure its not leaning out.

to add another bit of info the WOT switch can work with the push button activation as well, basicly even if you push the button it wont activate until its WOT and both have to be active for it to spray, the window switch replaces the button activation and kicks in when the rpms are right instead of when you hit a button, I would recommend wiring in your WOT switch no matter how you decide to activate it, it will save your motor,

a accidental n2o hit at idle or low rpms equals BOOM

I most likely won't do the window switch at first. I never plan to spray from the hole or anything with it. It's more to win a little money street racing like mentioned above. So I would only spray at WOT. I'm wanting to buy some 75hp jets because that's all I will probably need usually. I might have to try out the 100 shot a couple times, but would like to keep the 75hp jets in most of the time.

WHAT!!! All this info for a 75 shot? Man, you better put the 150 jets in. The old saying goes "Better to have it and not need it then to need it and not have it"


I had a 75 shot on a 3.1 liter v6 fwd 1996 cutlass back in the day, so why would you put a 75 shot on an LS1?

I don't think my stock trans will like a 150 shot lol. That's my main concern is putting all this power on my transmission. I'm sure the ls1 will be ok as long as I'm carefull, but the transmission is the week point. The max I'm wanting to go is a 100 shot.

We have put 39 passes on a stock 4l60e with H/C/I and a 150 shot on a 3830lb raceweight car.

Your car will be fine. I guess this is going on the bolt on car and not the heads and cam car.

Yes this is for the bolt-on car. So are you saying you had 39 passes before the trans went? Or is it still going? And were you spraying through the shifts?

Yes, it did 39 passes on the bottle before the trans went out, all mid 10 sec passes. Spraying thru the shifts. 3200 vigilante converter.

Your bolt on car makes less power than we did, so it should be ok for awhile

How many miles did you have on it when it went?

The car had 63000 when he bought it and the car had all the mods done to it right at about 70-75000. It wasn't his daily driver so it didn't get many miles afterward. So I would say at about in the almost 80-90k range the trans went and we put another stock one in and it went for a good while then we put in a built trans and its going still till this day with 100k plus still running mid 10's on the bottle.
