you can have 20 bottles...but its just gonna slow you down. If you use a whole 20lb bottle in one race your engine will blow. A safe amount is a 35 shot of WET nitrous. you have to have wet nitrous because we have a returnless fuel system. honestly...i think your in over your head because nitrous is a good way to blow your engine if you dont know everything about it.

how much NOS you can handle depends on what kind ov celica you have. ive herd of GT celcias spraying 75shots a lot with no problems, but in a GTS a 50shot can melt some parts

was....5speed with i/h/e
15.41 @ 89.30mph 2.282 60'

is....04 srt4 stock
13.936 100.15mph 2.177 60'

you have a GTS...the compression is super high already...dont go over 35 shot w/o running the risk of engine damage.

if you run a 35 shot you wont damage anything if its installed correctly. be sure your always at WOT when your spraying.

yup. and if your thinking '35 shots doesnt sound like a lot!' just think about how it would be if you had a supercharger in your car...its about the same power thumbsup

you can go higher than 35 shots...but the higher you go the faster you will put wear on your engine.

I have 75 hp shot of NOs on mine. I have the Zex system so it only activates when I am at wide open throttle. It makes it safer... Anyway, I have not had any problems with it and I have ran about 6 bottles so far...

You can get Zex in a 55hp, 65hp or 75hp shot.. The system comes with all jets for these setups...

lets start with the mods,you want to squeeze a big shot.you need at least Cold Air Intake not Short Ram,and exhaust.if you get headers it would help alot.reason:CAI helps ecu to mix fuel richer,e/h facilitates the expulsion of the extra "exhaust material".you need to run good fuel when you are squeezing.c12,c16, or mixture of 93 gas and ethanol mixed 8 to 1.you have to change the plugs for the run to (i will give you correct plug later,its ngk bkes 6 or 7-11)not sure about the number but i have a few left so i will look at one later.you can squeeze it in two stages using the nx sx2 nozzle. 1st stage at the throttle when you go wide open and 2nd stage in you hand with a t shift and button.the 2nd second stage should be wired to the 1st stage so that it cant be activateed unless the first stage is at wide open throttle!i hope you are a good driver cause the set up is mean!the difference is like jeckyll and hyde!.i dont want to tell you what shot to use cause i dont know your experience with nitro,but a 50/50 is good you can work you way down from there to what feels comfortable for you and it doesnt have to be equal as i said, what ever you feel you can handle! but dont work your way up from the 50/50 until you are accustomed to the car when it hits lift at wide open it lights up the tires( get drag radials,i use xtreme 555r nitto) and you are always there from the time you hook in first and floor it! good luck and dont mishift!

allow me to edit my statement: you CAN use nitrous at low rpm's (2.5k and up is fine) as long as you are at wot (wide open throttle)

a heater kit would be a good idea, especically since you live in VA where it can get pretty cold in the winter. optimal temperatrues for a nitrous bottle is 80-90 degrees..so obviously in the summer you won't need the heater most likely thumbsup

The bottle warmer heats the Nos to 77 degrees... It is realy a preasure thing though... You heat the bottle to get the preasure to around 900 or 1000 psi...

it does what is called 'purging'. what it does is it lets out a quick hit of nitrous through your system. this is usually done before a race and makes sure your your nitrous lines are clean & free of unwanted vapors so the nitrous can enter your system in the soleniod form (yes, solenoid...the optimal pressure for nitrous is 900-950--as stated earlier--and this pressure makes nitrous 'solid' as opposed to being a gas.)

I don't know what you mean by solenoid.. A solenoid is what opens the valve to release the nitrous liquid into the Intake or like in a purge out to the air...

The purge system is what you see in movies like fast and furious... When he rolls up to the line and this fog shoots our of his fender wells. It looks cool and surves a purpose like stated above...

correction--its liquid, sorry..not solid. your use of the term 'soldenoid' is correct.

Yeah, but you would have to have the bottles strapped to the Hood of your car or sweat to the oldies in the inside. wink

i forgot to add that my second stage is richer than my first you can do that by changing the fuel jet to the next higher jet value.example:if the chart tells you 50 shot equal 35 nitrous and 20 fuel jets you would leave it as is for the first stage but for the second stage you would go richer by changing the 20 fuel jet to a 22

its called purging,and yes its to get nitrous liquid to the solenoid and not the gaseous form,or the car would bog or misfire when you squeeze.about the sqeezing nitro at 2500 rpm,well, it can be done(nitrous dont kill motors,people using it incorrectly kill motors)but the stress on the motor would be a lot more,cause of the torque load at low rpm!it will be 3 times more at 2500 than at 7500 rpm! on my race car i used to free rev to 3000 and then hit the nitro to clear the line,instead of purging,but those are buillt motors bottom up! not stock like the celica!blow or go! aint nothing like nitro!

NOS (the company) desribes the dry system as:
"A "dry" nitrous system simply means that the fuel required to make additional power with nitrous will be introduced through the fuel injectors (remember, fuel makes power, nitrous simply lets you burn more of it). This keeps the upper Intake dry of fuel. We accomplish this by two methods. First, is to increase the pressure to the injectors by applying nitrous pressure from the solenoid assembly when the system is activated. This causes an increase in fuel flow just like turning up the pressure on your garden hose from 1/2 to full. The second way we can add the required fuel is to increase the time the fuel injector stays on. This is accomplished by changing what the computer sees, basically tricking the computer into adding the required fuel. In either case, once the fuel has been added, the nitrous can be introduced to burn the supplemental fuel and generate additional power."

NOS (the company) desribes the dry system as:
"A "dry" nitrous system simply means that the fuel required to make additional power with nitrous will be introduced through the fuel injectors (remember, fuel makes power, nitrous simply lets you burn more of it). This keeps the upper Intake dry of fuel. We accomplish this by two methods. First, is to increase the pressure to the injectors by applying nitrous pressure from the solenoid assembly when the system is activated. This causes an increase in fuel flow just like turning up the pressure on your garden hose from 1/2 to full. The second way we can add the required fuel is to increase the time the fuel injector stays on. This is accomplished by changing what the computer sees, basically tricking the computer into adding the required fuel. In either case, once the fuel has been added, the nitrous can be introduced to burn the supplemental fuel and generate additional power."

you can review the overview for the other two types of nitrous systems (wet and direct port) by linking here: nosnitrous.com: overview of the 3 basic nitrous setuips


I know how the different nitrous setups work smile I was just stating that it's possible to use a dry setup on a returnless fuel system like the celica's in response to spaztikid's post. What you just posted describes how a dry system works on a car with a fuel system that has a return line going to the fuel tank. Fuel pressure regulators and boost-sensitive fuel pressure regulators (FMU's in boosted applications) work off of this system by restricting fuel return flow to the gas tank, thus raising the pressure in the system and causing more fuel to come out of the injectors while using the same pulse width and duration. But it's not that simple with Celi's. There's a way around it, as there are some '02 Maxima guys running a dry setup on a returnless fuel setup. thumbsup

just wondering, but when is the best time in a 1/4mile race to spray, and how long does it spray for?

was....5speed with i/h/e
15.41 @ 89.30mph 2.282 60'

is....04 srt4 stock
13.936 100.15mph 2.177 60'

OK, you can change the jets in the nitrouse system and yes it does make it richer but, earlier you said you had a 50 shot stage one and a 50 shot stage two. If your jetting is not the same then your are not running two 50 shots. Changing the jetting is what changes your shot HP.. Istarted minat a 55 shot and then re-jetted it for a 75hp shot...

I was told by NOS and Zex that you cannot use a dry system on our cars without major modifications. A dry system shoots pure nitrous into your Intake while a wet system sprays nitrous mixed with gas... That is the difference.

1/4 mile... Hit the nitrous from 4700 rpm to 6500rpm shift then do that through all gears.. You shouldn't have the nitrous on for more than 10 seconds a shot.. The heat build up could possible hurt the internals. That is the risk with nitrous.

why is that? because of compression. according to NOS's website,
"...provide maximum reliability from most stock engines using cast pistons and cast crank with few or no engine modifications." more here: http://www.holley.com/HiOctn/TechServ/TechInfo/NOSTech5.html

so the celica is one of the exceptions?

according to NOS' website:
"It is possible to hold the button down until the bottle is empty. However 15 continuous seconds at a time, or less, is recommended."

also taken from the same page:
"Nitrous can be safely applied above 2,500 RPM under full throttle conditions."

more here: http://www.holley.com/HiOctn/TechServ/TechInfo/NOSTech5.html

so basically, in a 1/4 drag race you can start using the bottle once you get about 2,500rpms (as stated above) because a stock celica runs in the 15 seconds...you should be able to hold the button down the whole 1/4 because that should never be more than 15 seconds..just make sure your at WOT (wide open throttle...flooring it) thumbsup

Ok here is the deal... You can hit the nitrous at 2500 rpm's in a mustang or corvette but, in a celica it just bogs down because you are shooting to much fuel into the system at once...

You cannot buy a dry system for a Celica... Try it... Call Zex or NOS and see for yoruself... I did...

And if you ever buy nos and hold the button down until its empty make sure you call a tow truck...

quote by hybrid:
and who told you that a 35 nitrous and a 20 fuel does not equal 50 shot and who also told you that if you change the 20 to a 22 its not a 50 shot.i use a nx jet chart thats what they have printed! you said it yourself the second stage would be richer and thats why i did it that way.i have seen jet charts showing both combinations as 50 shot i simply use the one that has the bigger fuel jet for my second stage!btw you think the nx engineers got a celica gts and hook the nitrous up and actually tested what shot it can and cannot take! numbers on paper,averages,speculations based on certain parameters etc.not real life tests with this fuel and that modificatiions! its people like you and me who would have a chat with the techs and say well i did this and that and i have this and that and this was the result.i'm not new to nitrous,a lot of my buddies use mustangs as their race cars and 75% of them are built from the bottom up(special ground nitrous cams too)to handle big shot dual stage nitrous and we talking 500 shot up!

and also i definately didnt say you could use the whole bottle...as stated above 15 seconds or less is the recommended type.

and since obviously you have some experience with nitrous (i do not) why would the celica bog down? wouldn't more fuel + more oxygen equal more power? i guess you said no..but i was just wondering as to why this is.

in any case...would it still be faster than stock times even if you started at 2500 rpms? if not (or even if yes) what rpm do you suggest laying on the button in the celica gts?

i dont think that anyone would want a dry system on a gts,unless they dont know anything about nitrous and anyone competent enough to hook up a nitrous system correctly and know about the gts 2zzge and fuel system would not entertain the thought!dry systems introduce only nitrous into the engine and helps the fuel(fuel makes the power)burn more efficiently!its about 2 parts o2 and one part nitrogen which actually tames the o2 from burning to vigorously!it does this by increasing the temperature at which the molecules start coming appart which is about 500 degrees.no matter what "THEY" say about nitro the shit doesnt start hitting the fan until it reaches about 500 degrees!the heat build up in the cylinder from a dry system is from running lean that is why adding fuel to make it a wet system is better.fuel helps to cool down the cylinders also,even if you are running advance timing.nitrous kills a motor by 1)runing lean,it can cause detonation which can wreck a motor and 2)to big a shot can cause to high a cylinder preasure which can cause detonation and blow head gaskets seals etc.
I AM SURE THAT SOME OF THE STUFF MENTIONED ABOVE YOU HAVENT HEARD FROM NX OR ZEX!they know but wont publish it cause the average joe just want to hear,ok its in,50 shot, this button is to turn it on,...the serious racer however wants the whole nine yards plus some to push the envelope even further! call nx or zex and ask one of the techs if he ever heard of "plug indexing"!if he doesnt give you the answer,i would have proven my point about people like us(the ones out here who actually tries the shit on our cars)

in any case...would it still be faster than stock times even if you started at 2500 rpms? if not (or even if yes) what rpm do you suggest laying on the button in the celica gts?

quickly:
1)try to be specific and factual when it comes to certain things.you can squeeze and use all the nitrous from the bottle!it depends on what size bottle you are using or maybe you have only seen 10 lbs.

2)bogging down usually happen when the nitrous is not jetted properly,to much fuel,blocked nitrous solenoid/line.
it wont happen that easily if it was the other way around(to much nitro)

3)it can bog at low rpm because you are asking the Intake runners and head to injest a massive amt of "material"at an rpm where the head cannot possible flow that amt of air/fuel mixture!

4)usually if its jetted right and you squeeze at say 2500 the revs would shoot up,some people do that on cars to get the "out the hole" advantage,very little wheel spin and quick take off.but as i said earlier up the torque load is ridiculous at that rpm and can stress internals.this is how a lot of people lose a motor,not by detonation blowing a hole in the piston or burning rings,melting plugs,but by breaking con rods,spining bearings,this is the "stealth mode"that nitrous kills motors! everyone is more accustomed to the explosion/smoke associated with the "more active detonation"

5)i think for 1/4 mile time its best if you launch the car normal very little wheel spin and when you hook hit the button.hold until just before redline,release,shift,button again,through all the gears until the end of the track.

6)advanced racers do hold the button from begining to end while shifting! with their foot planted to the floor!

7)if anything needs to be clarified ask!,an in detail discussion of nitrous and its usage plus tips and tricks can fill a lot of books and can not be covered in a few sentenses!
