Celica Forums General Discussion Engine and Performance NOS For Celica...

Can anyone share with me their experiences??...

I wonder wat is the max shots we can have for the 1ZZ engine...

Thanx!!

if you are goin to go with "NITROUS" i would go with an nitrous express wet kit. with a 55shot. NXs nozzles are made to have perfest fuel nitrous mixured for optimum performance and peak horsepower

i love how you had to accent the "nitrous" to make him sound "ignant". Good info though. I have been thinking of going the safer way with dry, but then again i'm still under warrenty so no wet systems for me. i hear 55 is the most you should do with a 1zz wet setup

i heard it was the best and safest, and going any higher you wud be in risk of somethin goin wrong

Of course he accented it. I would have too. Everyone's gotta have NaWS!!1!one!

Actually, I've already got the Zex Wet kit installed, but according to my installer, I shd getting 100 shots currently... Pls pardon my ignorance ya...

I heard there's a guide for the hole-size of the nozzle, does anyone have any idea how much shots r there if the holes-size is 1.5mm??...

Zex is the safest from what I've heard, at least that's what most people recommend. 50-75 is the safest bet. You run the risk of blowing your engine or your tranny if you go much higher.

ive heard zex wet kit is a safe bet.. 50 shot is all i'd do

Wet kit is the only way to go with our car. Something about we don't have a return fuel line, therefore we can only run wet. Do a search on it, I don't remember what I read on it.

But for the wet kit, I would go with ZEX. It's got a control box with a wide open throttle switch (whenever you stomp on it, that's when it'll activate). It'll also dial itself down if you're running low on gasoline, that way you won't spray too much. If you do go with a bigger shot, 75-100, you'll have to get spark plugs that are one step colder than stock (that's for the GT, if you're running it on a GTS go two steps colder). If you have any other questions, just post'em up.

Ok guys, pls bear with me for 1 more question Is there a ratio/'formula' as to how much nitrous to fuel for the Zex wet kit???...

E.g.>> Like...75 shots Nitrous : Maybe 50 shots Fuel????

Hrmm... I'm a little confused, but I think I see what you're saying.

There's no real formula for it, cause you'll always be injecting the same amount of gasoline. The only thing you're changing is the amount of nitrous that's being sprayed. Therefore, the more nitrous, the more horsepower.

I'm currently using the HKS racing plugs, seems ok so far...

After using NOS, there's tis "tick tick tick..." sound during my engine idling, seems like the valves r a bit loose, does you guys encounter tis as well???...

Valve chatter is a very normal thing for celicas. It's also something I hate, but it just comes with the car.

Phew...I'm glad to hear tat...thanx bro!!



I'll take some pics for my setup & post them here, then you guys can give some comments then, but...err...if the pic/s size is too huge to post here, how can I reduce them? Can anyone teach me tat???...

Well if your size to big, do this

Go to your start menu

click on program/accessories/paint

once you're in paint:

click file/open then search for your pic preferably desktop (is where i save my pic b4 modifying it) ^^

Once the pic is loaded in your paint program:

Click file again and just click save ass (JPEG)

and wahla smaller size but same pic size get it? got it? GOOOOD ^^

Ok, done...Thanx so much for ur advice!!!...

Now I can post more pics to share with you guys...

from personal experience, you wouldn't even believe how much fun this stuff is

As long as it dosent sound like marbles droping I think it would be alright

the Zex wet kit automatically adjusts the fuel to nitrous ratio, that's why it's the safest. Also it only opens at WOT so you won't cause any unneeded stress.

Things that say 75 shot usually end up being like 55, so your 55 is like 35 which would really be...not much of a kick in the ass so go atleast 75

go 75, and while you're at it prepare to start replacing some things.

stick with 55

What are you talking about?

READ THIS^^^^

THEN READ WHAT I POSTED. Now that we are on the same level, let me break it down to a simpleton level. Running a 75 shot on stock internals is stupid.

Poor advice. What these "things" mean is that the 75 shot doesn't give the full 75 HP increase, that's what those numbers mean not that the stress on the internals is equal to a 55 shot. Run a 55.

You talk out your ass more than any other newbie I've seen. Do you even begin to understand what's needed for nitrous? You bought the whole kit from zex, but do you know why you needed any of that stuff? Read my original post in this thread and educate yourself. If you need anything explained, I'll try to bring it down to "simpleton level".

Aside from that merlin, the moral is that a 75 shot every now and again isn't going to make your engine detonate or anything like that. But it is putting stress on your engine that's not good for it over a prolonged period of time without some beefed up internals. I assume you're buying this product cause you want to have some fun with it, you will be able to use this for a lot longer without anything to worry about on a 55. After a year or so with the 75, (depending on how often you spray) you may start having problems, that what it comes down to.

I have to disagree. Nitrous, if done correctly, will not harm the engine. Unless you're running NX's 75 shot, which is a true 75 shot, and that's a different matter. But for ZEX's 75 shot, on a gt with the right precautions, I think it's just as safe as adding a turbo or supercharger. Of course EVENTUALLY you will have to replace something, but that's far down the road.

True, if there was a kit to over-do it's the Zex kit. Personally I tend to go on the conservative side of things, I don't feel it's worth the risk only because nitrous can be abused, though with the Zex kit that is much less of a concern. Ultimately it all depends on your style and what your comfortable with. However Merlin is right about the fact that the Zex kit is the most "idiot proof" of all nitrous kits. I would fight you a lot harder if we weren't talking about the Zex kit because nitrous has an aspect of "user abuse" unlike a turbo; ie anyone can hit the red fucking button in an average nitrous kit, not everyone knows how to increase the psi of their turbo. But the Zex is all automatic so it should be more forgiving. Personally I would still go 55, it's up to you.

As long as it dosent sound like marbles droping I think it would be alright [/quote]

Come to think abt it, it do sounds something like marble dropping man...

One of the many talents I picked up through life.


You fill the tank with air, wait...its nitrous isn't it...isn't that what you fill your tank with?


I didn't need any of it, however I still bought it. But let me see, if I wanted to go faster...and there is some crazy rumor floating around that n2o seems to do that every once and a while, then I guess I bought it...to speed things up. I don't know yet though, I'm still thinking of why I bought it, I'll keep you posted.


Oh please great master, Break it down one more time...

There's a way to do things that makes you sounds intelligent, and there's a way that makes you sound ignorant.

both of which i covered, maybe. :koolaidman:

No, I'm pretty sure you only covered one way. And evidently you don't understand what any of that stuff does because Zex plugs definitely don't make your car faster.

zex plugs??? wtf are you talking about? YOU MEAN TO TELL ME SPARK PLUGS DON'T MAKE YOU ANY FASTER!??! NO!!!!!!!!!!!!!


Seriously man, take your finger out of your asshole and leave this post alone.

You're an idiot and know nothing about cars. Go buy some more speed chips off ebay.

I'm the idiot? I'll send ya some 30hp spark plugs.

Speed chips? hmmm sound tasty...what flavor should I look for exactly?

Calm down, fellas, no need for hostilities. If you are gonna make a comment about how or why something works, back it up. The plugs help to create a more efficient burn. You can lose power if the mixture does not burn properly. It's not something insane, but it's still a few horses that you can make.

Hey guys, we r all on the same side aren't we??...Fellas Celican as so to speak, we r supposed to stand as 1 & make our rides better, not going against 1 another rite???...

The hostilities you guys r exchanging is making me feeling bad as I'm the 1 who started tis discussion...

Yeah yeah, it's just he thinks he knows everything about the celica, when in actuality, he knows very little. He tried telling hundreds of people that we were wrong about that speed chip off of ebay. Then he tells you that you're going to start tearing up stuff with a 75 shot from zex, which you won't. But whatever.

damn merlin, your an ass. Let ppl have their damn opinions and leave it be.

I'm not going to say anything, because I don't want this thread to keep on going only because someone wants to bitch about something or to someone. So do us all a favor and let this thread die.

That's not helping either. Megatron, maybe you should try New Celica Dot Org for your answer, as they have a whole section for nitrous.

I've tried, but there seems to b no reply fr there... I just wana understand NOS better fr you guys overseas, cos NOS is actually ILLEGAL in S'pore, so not much ppl here have try it...

Anyway, thanx for all help!Really appreciate tat...

1 if used correctly nitrous is actually less wear on your car than a turbo. think about it if you are boosting and adding an extra 50hp to your car at all times it's a lot more wear on your internals and transmission than if you're running an extra 50hp only once in a while and only for a few seconds.

2 in the olden days before computers and stuff you would have to spray nitrous with a stupid red button and if you did it at the wrong time you wouldn't get enough fuel cause detonation and blow up your pistons, but nowadays most kits come with auto activation that prevents idiots from ruining their cars and also are more precise so the amount of nitrous you get is consistent and calibrated, so blowing up your car is not really that much of an issue anymore.

3 wet is much more safe than dry kits. a dry kit is dependent on your stock fuel injectors to offer the fuel it needs to go, while a wet kit uses a nitrous nossel and a fuel nossel to provide fuel and nitrous at the same time, this helps to prevent detonation, something that happens when you are too lean.

4 the way nitrous works is by adding more O2 to your engine, it's safe because the O2 is bonded to the nitrogen until it's heated to about 500degrees then it breaks off and can be used for fuel in the combustion chamber. This is why you wouldn't want to spray liquid O2 into your car because the tank could be very volitile and explode easily.

5 you need colder spark rated spark plugs as a safety and performance factor, they don't give you extra HP, but the colder plugs are able to handle the increased combustion chamber heat caused by the nitrous. colder plugs run colder they disipate heat to the engine block better than hot plugs. you want to have the correct plugs for your vehicle though, because they also won't work if they are too cold, but if your going to be using nitrous to compensate for hotter combustion chamber heat a slightly colder plug is a good idea.

6 I don't know a lot about the specifics of our car and what kinds of things it can hold up to, but if you can boost 75 hp safely then you can probably nitrous shot 75hp safely. the only thing about the wet system that would be a concern is usually it's one nossel at the intake near the throttle body. you might run into issues with the fact that since it's not directly injected into each cylander it's possible that different cylanders could get different amounts of power if the fuel mixture to each cylander is uneven. this could be bad, the best way would probably to have a computer that knows when your shooting the nitrous adjust your injector duty cycle but I dunno if this could be done with the e manage or the power fc.

hey kid, you didnt do a good enough search on nitrous on this site and even on newscelica.org.

there is a post on newscelica :NewsCelica.org Forum > Celica Discussion > Forced Induction & Nitrous > NX toasts my motor.
that can give you some valuable insight into nitrous and its uses and misuses.

btw; make sure the people you are getting advice from reallly know what they are saying and is credible and experienced. bitrous can be very expensive and dangerous.

any questions i will try to answer if time permits.
good luck with trying to know about nitrous kid thats the best way to go

just get a zex kit keep it a 50 shot and use the 75 shot on raceday and it should be cool on the stock motor and 1 colder plug is good too

sorrie i'm the newbie hea... so you guys are saying that it's save to shoot 55 psi on a stock internal celica... i'm talking about a GTS not gt.. rite?

We are all in agreement that a 55 shot is safe (provided it is installed and used properly). There are differences of opinion with the 75 shot. I agree that for the most part it's fine especially with a Zex kit. However, I wouldn't advise someone put it on their car if it wasn't a Zex kit just because nitrous can be misused and abused. Others feel a 75 is fine no matter what.

okay, i see...

^^ to clarify, put it on there car as in put a 75 shot not a non Zex n20 kit
