Ok Guys, I've got a 98' Civic EX that is pretty much stock, besides really an Intake.......

And I just ordered a ZEX dry kit for my car. Now, all i need to know, from SOMEONE please...

1)What will i need to do to my SOHC D16, besides gettin some colder plugs??
I don't wanna waste all this time and money, and set it all up, and the FIRST time I spray it, BOOM, I blow something up.
I know everyone said go with a turbo, but my budget was just not booming right now, and this was pretty affordable. I mean, I'll have another $300-$400 bucks to play with after I install all this to buy other components that I will NEED to keep from tearing up something, or will NEED to help with the boost.
So does anyone have any ideas on what i'll HAVE TO HAVE, or will atleast NEED on a $300-$400 budget to take full advantage of the ZEX dry kit? THANKS EVERYONE!!!

 

keep the shot 75 or lower, and you will be fine....

 

1. you will have to advance your timing. i think to 16-18 degrees.
2. you already know about the plugs
3. and keep it at only a 50 shot. any higher and you will damage your engine, some people have gone to 75 shot. its hard not to have a lead foot.
4. remember that it will cost about 3-4 bucks a gallon for NOS.
5. you should go turbo. its cheaper in the long run.

4 bucks a gallon for NOS, 10 gallon bottle= about 40 bucks.
average 10 gallon bottle will last about 10-15 good shots of speed << roughly depends on how you use it ofcoarse. roughly last about a week or so on the streets.

just a typical run down on the cost of everything.... just remember you will be spending about 100 bucks for every two tank fill ups.....

you will be going over your budget quickly........hope this helps ....

 

SO i could run 65 or so pretty good? I've had peeps tell me about retarding the ingition timing and such? Is that true? And what bout my stock clutch, will it prolly be able to handle the stress?

THANX!!!!

 

i dont think you want to retard the timing, because you want more fuel with the juice to create a solid bang in the engine.
if you retard, it you will burn a hole in the piston because you wont have enough fuel ratio with the juice...

the clutch is fine as stock, again it depends on how you drive with the NOS

 

AHH...SO ADVANCE MY TIMING? That's pretty much the same as Retarding, or is that the opposite? Thanx man.

 

your clutch will be able to handle it as long as u arent running on drag radials or slicks. i've heard stock clutches+drag radials=burned out clutch. i wouldnt push a 65 because u have a 1.6 liter. i mean you can do it, but would i recommend it? absolutely not. but then again i'd never recommend nos to be honest. go with a 50 shot, colder plugs, maybe a headgasket? i may be wrong there. oh yeah and he's right, u gotta advance ur timing w/ nos

 

OK THEN,,, let me be a newbie and ask you THIS.

When should i spray it? I've been told to try and not spray in 1st gear because of the stress on the STOCK tranny. Is that true? And maybe only in certain gears? I know that the dry kit i ordered only sprays at Full Open Throttle right?

 

retard is making the timing slower, which puts less gas in the engine per cycle.
advance puts more gas in engine per cycle. and is a comfort zone that helps you not to burn your cylinders. because your ecu will add the necessary fuel, but it has a limit as to how much it will add. so the advancing helps with the fuel/NOS ratio.

also since you will be burning more fuel, you will ofcoarse have bad gas mileage, but the car will run smoother with the advance in timing. its a give and take.

 

well the reason they say not to spray in first gear is if your spray at below 3,500 rpms, you are more like to mess up your cylinders,,, so you want to spray around 3,500-4,000.. it has to do with your engine.<< remember this falls into the fuel/NOS ratio. at those low rpm's your not getting that much fuel for the NOS. which is bad. bad fuel/NOS ratio is why people mess up their engines.

will the engine blow up if you spray at 2,500 no.. but is it more likely too over time yes.


and no need for a new head gasket. use the oem one, and keep it at 50 shots and you will be fine. if you go with a higher shot, im not sure if you need a new gasket.

so you say advance my timing 16-18 degrees? Are you pretty certain about that? Will my car run fine will just runnin' without the spray still? (I understand the bad fuel milage)

And what would i need to do to my d16 to be able to pretty much handle up to the 75 shot?

MANY THANX MAN!

 

i know the oem timing is at about 12 so it is roughly a 4degree advance from oem... which leave it at about 16-18 timing flunctuates 2-3 degrees naturally so if you keep it at around 16-18 you will be fine.. double check with any shop, just tell them you are doing a NOS install and you wanted to know what the timing advance should be... that information shops are more willing to give out. how to install most will not tell you... but ask around ,, i am pretty sure thats what i was set at.


and you can leave it at that degree of advance for normal driving also, but realize you will get bad gas mileage, and you will be adding deposits on your cylinders because your not burning that extra fuel.. when you mix it with NOS everything burns. without NOS you will leave deposits for sure and over time it will become a problem.

i have never gone up to 75 so i can tell you what else to do.. but if you have stock internals and you want to run solid without any repairs i would stay with 50.. i ran this set up for about 2 years no problems at all... car has 165,000 miles and runs great.

 

i know you said you couldn't afford it, but i would save up and go turbo, or really same up and go B18.. homemade turbo LS..?

 

you DO NOT advance your timing. nitrous causes a more rapid burning of the fuel air charge. If you advance the timing you are firing early which goes hand in hand with heat production and a leaner mixture. While running nitrous you need to be at a richer mixture to add more fuel for a richer mixture so it burns evenly and most important to cool the piston during the combustion process. i highly reccomend you dont advance the timing it should be retarted.

 

you are supposed to retard the timing 2 degrees for every 50 shot of nitrous.

 

The misinformation is strong in this thread.
