Using Nitrious? Options

[deX]

What do you need to modify to shoot nitrious in your car? I have an ST so do I need to do anything to it before I buy a bottle and hook things up? And exactly when do you use nitrious, what RPM's? I might wanna try it out!

[Matty19]

depends on how big of a shot your gonna use, as to what modifications you need to do, also only use it at wide open throttle and above 3000 rpms. let me know exactly what your aiming for and i'll let you know how to do it.

retard your timing

[Sh0gunkid8721]

I think that NOS is such a waste of money...Why get a SHOT of NOS that would last you like 5 seconds when you can turbo or do a swap and gain performance for as long as you have your car?? Just my opinion though...im not a big fan of NOS

[94celicaguy]

i also hate it when people (nobody in particular ) call it NOS when we are talking about nitrous. there is NOS, Compucar, Edelbrock, Nitrous Express, Zex, etc.......... it is nitrous oxide in general. bunch a' torettos!!!!!

[Matty19]

I think nitrous is one of the cheapest horse power mods you can get. It may only last a couple of seconds, but thats all it takes to kick someones ass!!! Plus the fact that it is only used for a couple of seconds means that it won't kill the motor as fast. Nitrous is a good mod, especially if you dont have the money for a turbo setup, and it looks really f*cking cool when you purge. I say go for it.

[ghostdog]

one time I was using NOS and it blew the welds on my intake manifold

then the floorpan fell out... haha

[SXR]

Sounds like a movie to me. Fast N Furious did it.

[FallenHero]

HA, Why did the floorpans fall off anyway, and what was spitting out those green bolts? : )

ANYWAY, N2O is great for the money. On an engine like ours it can last up to 15 seconds on one shot. (running it at low RPM's is REALLY bad though.)

I think the easiest nitrous upgrades you can do is the Zex dry nitrous system. You can buy a Zex cone filter to put on an intake and it has a place to put the nitrous injecter so you dont have to drill a hole in your intake tube. It injects the nitrous into the intake so you don't need to do half as much installation with selenoids etc... Just install the nozzle with or without the Zex air filter (it just makes it easier with that) install the bottle, install the computer unit, run some wires and install arming switch. The nitrous is administered when the system is armed and your at wide open throttle so you can screw up the timing you should shoot.

takes like 3 hours sor so, and cost a lil over $500, up to 75 shot depending on injector but if you run that much you should retard your timing

Where didd u get the Zex kit and the filter for only 500 bucks?!?!?!

The most popular and safer kit for our cars is the Zex dry kit. I think they only have 55, 65, and 75 shot jets, but you can probably run either one fairly safely, without doing serious long-term damage to your car. Damage to your vehicle while running nitrious is all on the driver...

All you need for the install, a drill, screwdrivers, wire cutters/strippers, and cooler spark plugs. Running low shots, you can probably get away with not retarding the timing... but I can't say for sure. I've ran up to a 75 shot, with little problems. I only sprayed while racing, and it was always in mid 3000rpm, in either 2nd or 3rd gear. 2nd isn't very safe... but you can.

How do you retard your timing ? And what does this mean?

2nd that!

[jayi12-15psi]

When using a shot of nitrous, what happens when you shift gears?

With most setups there is a WOT switch that only allows you to use nitrous when your at Wide Open Throttle. so when you shift gears and let off the gas does the nitrous shut off untill you floor it again?

[sirrahtap]

the nitrous will go when you are pushing the button
so when you shift, just lift off the button

[Matty19]

Just get a zex kit, they are the easiest to use and install. All you have to do is drive the car, and the nitrous takes care of itself.

[deX]

so does the zex kit have like a button you push when you wanna use it or does it just come in whenever??

On the older 94-95 Celica's... retarding the timing is done simply by turning the distributor a certian number of negative degress. Of course, use a timing light and make sure you have your adjustments done correctly.

On the newer OBD-II 96-99 Celica's, adjusting the timing is done with an OBD tool (little computer gizmo)...

Retarding the timing means, basically, retards the ignition of the spark plug to fire slighty after TDC (top dead center, when the piston fully compresses the air/fuel misture).

As far as Nitrious engaging between shifts, when the throttle isn't wide open, I think it retards and delays until the throttle is wide open again before engaging. Like I mentioned before, try not to spray in 2nd, unless you know what you're doing. Spraying in 3rd gear is safer because unless you're gonna run 13's or 14's... you probably won't shift past 3rd in a 1/4 mile drag...=]

It does have a trigger... you can flip it on...but it won't activate until WOT... but I can't gurantee that...=]

[ToYCeLi8]

I agree with kwanza. Especially b/c whenever i race i feel my car loss sum power in 3rd, it doesnt pick up in 3rd like it does in 1st and 2nd.

Is your car an automatic?

if so, many gears to yo have?

[ToYCeLi8]

My car is a 5 speed. I seem to lose some momentum everytime i am racing and i shift into 3rd? Its happened a lot with integras and some SI's. Is there some thing i can do to keep that speed? Besides nitrous?

[Guest_Matthew_*]

keep your rpms up

or get a turbo

how many times have you all refilled your nitrous bottle?

how much did that cost you over time?

could you do the swap with it?

i think so

[west_minist]

do you go to the rev limit?

[Kwanza]

I believe what he's trying to say is, Our cars (US Spec mind you) don't pull as well in 3rd gear as Integras and Civics. Oddly enough, I agree.

As far as costs of filling nitrious bottles go, it's about 40 bucks a full bottle here, good for a LOT of runs. It's a lot cheaper than a turbo system, guranteed, and doesn't come with the endless complications a turbo can yeild over time. I'll also say, I don't spray anymore (had an unfortunate accident before). Either way, nitrious is far cheaper than a turbo and can yeild similar results as an unbuilt 5sfte or 7afte. Also note, you can't compare the two. Nitrious is mainly for the straight line drags, while turbos are pretty flexible. If all you want is a quick boost in a straight line... nitrious is cheaper, safer, and can yeild the same, if not slighty better results than a turbo on our motors.

And if you wanna know, I've hit 14's with 97-98 mph trap speeds on the tracks... spraying on an all-motor setup...an ST. ;]

Kwanza - You have any slips? 14's? Thats fast!

3rd Gear - Yeah the celica pretty much sucks in 3rd gear, lol... SI's third gear rocks tho, thats where the power is in SI.

[bonzaisushi]

i had a zex kit on my celica, then i got rid of it and sold it to my friend and he has it on his prelude, its soo easey to install were talkn like 30 mins, here in kansas its 3.50 a bottle so the 10lb zex bottle is 35, and it does go by fast, i ran a 55 shot, never got to installn the 65 or 75 nozzles. its not like F&F where u hit the button and WHAM!!! u can feel it but its not like screeeetchhh the tires screetch in 3rd, u can feel some sort of a kick. but just arm it after ur out of 1st, cuz the at transmission doesnt like it when u arm that sucker in 1st. hope i helped.

[jayi12-15psi]

would I be able to retard my timing or anger by myself? or should I have a mechanic do this. would retarding the timing have any effect on the feel of the car otherwise?

It's not difficult if you have the tools, but too much retard can cause your car to misfire.

And dex, I do have slips somewhere, but I can't seem to locate them (might have been left in that car when it was sold). It was hitting low 15's that night, all night, with 93-94 mph trap speeds. I finally hit 14.9 and then 14.8 both with 97 mph trap speeds, I think. Can't really remember. Either way, with trap speeds like that, a typical car with good traction can hit mid 14's. It's mostly my traction that was bad. I'll search a bit for those slips, I'm sure I have at least a few. I'll post it if I find it.
