I have a bolt on only LS1. Mods are listed in my sig. Will it be necessary to change my lifters, pushrods, springs before spraying on my stock motor? I am only looking to spray a 100 shot. I have very little N2O experience so I need all the help/advice I can get. Thanks

I will read the sticky's more thoroughly tomorrow at work but I thought I'd get some advice to complement the info

i dont believe you have to...but spark plugs should be...

change your plugs to TR6
start with a small shot
Get some gauges to monitor things esp AFR
pull timing relevant the to size shot you run

If you're only running a 100 shot I would just use a dry kit and change the spark plugs.

Well this is the kit I'm looking to buy http://www.ls1tech.com/forums/showthread.php?p=8086485&highlight=#post8086485 Any thing I should know before I purchase it? Any reason why I shouldn't?

thanks! I currently have NGK TR55 plugs.. Heard I'm gonna need TR6's.. is that right? Also - this is totally off subject but don't you have a video of that 8.91 sec run on youtube?

and watch for any KR's(spark knock) and run premium gas

grrrrreat. what does KR stand for? and how do i watch for spark knock again? haha.. seems like the only thing i'm good on is the gas since i always run premium..

so to recap - I need to get an AFR gauge, change my plugs, and check for spark knock (however the hell i do that)... anything else i'm missing?

KR stand for spark knock , and if you get a AFR gauge get a wide band .

KR is knock retard isn't it? You should also have a window switch and a fuel pressure safety switch as far as I know. Also nitrous and fuel pressure gauges. Along with the A/F and maybe even an exhaust gas temp sensor.

Check out the stickies they are very informative.

I ^ used this for a general idea of the wiring/plumbing for a basic wet shot. I'm making my own system :)

the idea of spraying my car sounded great initially but the more i'm learning, the less appealing it is becoming. i asked a friend of mine, stock motor, and spray for some suggestions/advice. this is what he said:

lol well after you start spraying it you can kiss your strong running motor good bye. Mine slowy progessed down hill after i sprayed x number of times and pretty much detonated all the way through 4th gear pretty much every time i sprayed and that was with the TR-6 plugs. My advice would be a wet kit and a tune with race gas if you can get ahold of some that way its a little bit safer. But you gotta remember having nitrous on your motor is like a ticking time bomb. The motor will let go its just a matter of time. I know mine went lol just gotta make sure you can back up the funds for a new setup

The whole race gas thing.... i want to street my ride for the most part and run at the track every now and then so running race gas regularly just isn't feasible.. there are so many variables to consider when spraying. wish i had enough cash to subsidize it.. i'm thinking i need more $ for that "just in case shit" that might arise

I understand where your coming from. The fact is, nitrous is like any other engine mod with the same gains. Turbo, blower, as long as the system is tuned correctly and the proper safety precautions are taken, its not as dangerous as a lotta people make it out to be. There are many dry and wet systems I've seen that run good ol' 93 octane.

All I recommend is researching, maybe nitrous isn't for you. Theres always turbo, stroker, etc :)

Yeah forget spray I'll just spend a couple G's and do it right... would if i could... Well man I really want spray I guess I just don't know enough about it and I guess that's why it makes me nervous. You get hella gains for a small price and like you said, done correctly it won't be too harmful. I just need more info I guess.

He said that because your friend doesn't exactly know what he's talking about.


I've been running virtually the same setup for almost 2 years and numerous sprays with zero problems. Car feels just as strong if not stronger.

Buy the kit, get a window switch and TR6s and never look back. You'll be hooked and upgrading your fuel system to spray an even bigger shot sooner or later.

I agree with that.. So I'm gonna need gauges (which just look soo bad ass anyway), a window switch, and TR6's.. anything else? Is it necessary to get it tuned after installing the nos?

Get a fuel pressure gauge preferably electrical. A/F is optional but if you get one get it wideband. Otherwise it'll be just a fireworks display. Fuel Pressure safety switch (not sure if its included), and a WOT switch and filter seems to be included which is good.

Those are just a couple things that are pretty important. You can always upgrade your fuel injectors and pump just to stay on the safe side but isn't required.

On a 100 shot it isn't exactly imperative to get it tuned but it does help. I ran a 100 shot for about a year before I got it tuned.

craziness.. i know about the WOT switch. so the fuel pressure gauge tells me when my fuel pressure drops too low? and the fuel pressure safety switch? where does it go, what does it do? Does the filter just filter the N20?

Sorry to keep buggin but I'm clueless

My god every time I hear a story about nitrous that starts out.......my friend said........I know it is going to be bad and full of misinformation.

Your friend is WRONG, I have been spraying 150 shot for over two years, my friend in Virginia has been spraying 125 shot for almost 4 years. Our motors still run strong and neither one of us have ever used race gas. Maybe the problem with your friends set up is he didn't know what he was doing, if you install it correctly, use the safety devices and do all the changes......plugs, timing if needed and such you will be fine.

The fuel pressure gauge does exactly what it says, it tells you your fuel pressure so you can keep an eye on it if it gets to low. The FPSS comes off your fuel rail and when your fuel pressure goes to low it shuts off your system to stop damage.

Get a smater friend and a better tuner...
I know plenty who have beat the living shit out of their motor with spray, but it was done RIGHT. There was no detonation through 4th, the plugs were gapped correctly, and the tune was correct. It is all in the set up. You do not need RACE GAS for christs sake lol...

Just throw a decent wet/dry kit on there...have an EXPERIENCED tuner tune the PCM, and let 'er RIP! :D

PS- if you are worried about money, and "just in case" stuff, perhaps you should not mod any further. I am just being honest. Many people want this and that, but at the end of the day the funds always become the determining factor. Look if you want RELIABLE, get a Honda. If you want your motor to last for a decade but make sick power, set aside $1500 and get a cam, springs, purshrods and a tune and you're good to go. Stay away from N20 if you are worried.

If it were me, and I cared, I would get a tune. Why spend all the time and money an not tune the PCM to handle the N20? Not tuning could = engine in a bucket...seriously.

I have broken many things on my car and fixed em... I just don't want to seriously fuck something up. IF spray is achievable in a relatively "safe" manner, I'm down.. I am going to have it professionally installed and tuned so that's not an issue. And to address the "get a Honda if you want reliable" - I have a Honda - it's my daily driver... Thanks for the info man!

Agreed, but in stock form a 100 dry shot is about the highest you can go without pulling timing. My car is now dynotuned at 24 degrees but it was still operating at 80% on stock injectors. It now has 42#

Call Thunder Racing and buy a Timming Tuner. This device allows you to set a time delay on N2O activation. {allows you to launch the car on motor for traction} It also has timing retard function for when you spray the car. It also has a high rpm limit so you don't hit the rev limiter on the bottle.{this is a bad thing}. I had mine for 5 years it works great. These cars on a 100 shot run great.

Timing tuner huh? Hmm.. Can't I launch the car on motor without spraying with a window switch? The RPM is a questions I was getting to. On a basic setup, at what point does it stop spraying or - how do i stop spraying?

You can use the window switch. It will also turn the N2O off at the high limit. With the timing tuner you can do it all with one box. It's always a good idea to take some timing out when spraying 100HP or larger shot espcially when its summer time.

get a dynotune this >>> http://www.dynotunenitrous.com/store/scripts/prodView.asp?idproduct=194

i like it cuss it's a microswitch a window switch and has gear lock out. meaning you set where you want to spray (3k and up) and will shut off where you want (5250 you dont want to spray threw shifts) the gear lock out will let you spray in 2,3 gear and lock out first gear so that you can get traction in first gear.

and i sprayed a 100 shot for a while while i was on the stock timing, it was fine for me until i jumped to the 150 shot :devil:.... just to let you know what everyone knows already, TNT shots give you more than wht they advertise. my 150 shot was more like a 170 :D
