Celica Forums General Discussion Exterior Does anyone have NOS on their GTS

Looking into getting NOS in my GTS. Would like to know anything at all about this.

Would really like to hear from people who have it now.

skdmorse has it on his GT.

I know I'm looking for someone withit on a GTS thank you though

It really won't matter whether it's a GT or GTS...As far as problems and performance go

The reason I am asking is because of the lift on GTS which is higher and longer than the gt so I wanted some performance input.

If you get nitrous, i'd go with a 45shot. That will keep you safe and still give some boost. Also, any reason your going with NOS? Zex nitrous is a much better and safer alternative.

I think the lift would just be more inhansed with Nitrous... I cant see how it could effect it in a bad way... Nitrous just help sthe gas burn better so you can accelerate faster (Breif explaination)... As for an opinion I really like being on the bottle. It makes driving a Celica even more fun...

Have you had any reliability problems, and which system do you have?
Wet or dry?

GT doesn't have lift. You mean the rev limiter?

I was wondering about this for some time. I was afraid of the high compression in the GTS that a shot of Nitrous wouldn't be good. I don't know if someone did it and the amount maybe smaller like 25-50?. I think 50 may be too much. I would like to know also about this. Any light on the situation?

it does matter. the GTS has very high compression, and can not handal a lot of nos.

That's true...I'd probably go with a 25 shot

I have NX kit on my GTS its ok.. The big thing about the motor is the head,they have weak valves & springs.. I have not had any problems.. If you can find valves and springs U could run a big shot...

Where can you find valves and springs? I GOT MONEY!!!!! :whatever:

I don't know? I want some tooo...

What's the shot you are running now? It might be OK for me.

I am running a 35 shot.. When i talked to NX they said not to run anything higher than that.

That would be more than perfect for now. Thank you. Sorry, but how much was the kit?

I relly don't remeber but it was allot, The kit was really nice. easy to install. Just go on the NX web site..

Thanks again. I'll check it out and give them a call as soon as I'm able.

Can you post a link?

Have you taken the car to the track yet if so what kina times are you running?

I have not been at the track yet. but I am going to go this summer..

How is it activated?
Push button switch or full throttle or computer?

How much is alot.

j-bing has one. pm he

This [monkeywrenchracing.com] might help for some strong parts to go for our engine. a lot of money tho.

I have heard Zex is system to go with anybody have an experienced opinion about this.

Again, skdmorse - he has the Zex system

Some FYI before everyone gets all excited - Nitrous oxide injection is very much like a supercharger or a compression ratio increase in that, during combustion, it can dramatically increase the dynamic cylinder pressure in the engine - too much and you my have just caused serious damage to your engine.

Of course, when you significantly increase the cylinder pressure in the engine, you also increase the engine's tenancy to detonate. This is why almost all nitrous motors require retarded spark timing during nitrous oxide operation. The cylinder pressure increase is also why, when misused or improperly installed, operation with nitrous causes problems with head gasket seal and failures of the rings or pistons. I should point out that any number of things that put an engine into severe detonation, such as too much boost from a supercharger, low octane fuel, excessive compression ratio or overly lean air-fuel ratio will also cause the same kinds of damage.

Another challenge with a nitrous oxide system is getting the delivery of nitrous oxide and additional fuel at the correct proportions. If you feed nitrous to the engine without enough extra fuel, the lean air/nitrous to fuel mixture will make the detonation problem even worse. Combustion temperatures will skyrocket and catastrophic failure is certain to occur. If the proportion is such that too much fuel is delivered, the power advantage degrades rapidly.

As you can see, nitrous oxide is like any other power increasing modification in that, when used wisely and installed properly, it works well. Then used foolishly or installed incorrectly it can significantly reduced the reliability/durability of your engine.

Small doses of nitrous oxide can be used in stock engines to gain 25-35% more power. In my opinion, any more than nitrous than that with a stock engine compromises durability too much. This is not only true of nitrous but any modification. Take a stock 82 or 84 engine, up the horsepower to 300hp and do nothing to improve durability and your engine will eventually suffer. Once you pass the 35% power increase mark with nitrous oxide you need to look at things like forged pistons, better connecting rods, better bearings, etc.

Nitrous oxide is also a great value on a dollar-per-unit-power increase when installed and operated properly. The downside, of course, is the fun ends quickly. The power boost lasts as long as the nitrous. The average bottle is a 20 pounder and with a street V8 that might be worth 20 seconds of use.

So, nitrous oxide is not the instant-engine-failure many people think it is. When used properly and when dispensed by a properly designed and installed system nitrous oxide can be responsible for some phenomenal increases in power.

Isaac thanks very much that was the kind of info I was looking for. If you could provide the answer to one more question I would like to know about how much it would cost for a good reliable system.

from $450 to $650 plus installation

i got a question bout nos. does it spray all the time? like say your gonna race, do you turn it on and as soon as you go full throttle does it kick in? Then when you change gears what happens? Does it go off when you take your foot off the gas to switch then kick back on when your gas again or you have to press a button again?

this is what the buttons are for

Can't you also set it to spray at a predetermined RPM so that when you're racing it automatically "Kicks in" when you need it...?

I believe so
