If want to run the zex N20 kit at a 75 or 100 shot what else should I do to make sure nothing is damaged?

 

75 or 100? Umm...everything wouldn't be a bad idea.

You need at least better ignition and fuel. Even then, 75 or 100 shot of nitrous is a bit extreme on stock internals....

 

75 is just fine on a gsr. still safe but u might wanna reinforce ur **** first before spraying a 100shot system

its NO2 buddy...not N20

75 is good on stock internals...

100 ONLY, i repeat ONLY, if you know what the hell your doing and know how to tune it!

 

Like everyone says, 75 ok on stock motor, if you decide to run 100 shot, you will need a new fuel pump, fuel preasure regulator, higher flowing injectors. That should be good for now, unless you are one of those fools out there that is trigger happy, if you are(or know tht you will be) go ahead and build the bottem end, new higher compression forged pistons, forged rods, new valves, titanium valves springs and retainers. But remember, if you wnat to go turbo later, then you will have to build it for that, with lower compression pistons.

 

and no its not NO2 it is N20 nitrous oxide is composed of 2 parts nitrogen 1 part oxygen get a clue

 

i know i have to brush up on my chemistry but i think you're right pstreck

 

The use of nitrous oxide (N2O) as a performance enhancement has been traced back to World War II, where it was employed to give Allied aircraft "emergency" boosts in both airspeed and altitude capabilities. However, with the advent of jet propulsion at the end of WWII, the government's interest in piston-powered aircraft waned. And for the most part, nitrous R&D was shelved.

There were sporadic attempts at using nitrous oxide in race cars over the next few decades, but since for the most part it was a clandestine, closely-guarded secret, not too many people were aware of its existence.

Finally, in the 1970s, nitrous "came out of the closet" and was the hot topic of conversation. Especially since a number of entrepreneurs brought systems to market that were highly erratic, at best. It was at this point in time when a couple of successful automotive technicians and racers, Mike Thermos and Dale Vaznaian, saw there was a potential for nitrous - done right.

In 1978 Mike and Dale formed Nitrous Oxide Systems, Inc., and the rest is history. They didn't invent nitrous oxide - they simply perfected its use and elevated it to a position of prominence.

 

Also, what experience do you have with nitrous? I thought you've only had your car for 4 months?

It's better (for everyone) if you only talk about things that you have first hand experience with, so as not to mislead anyone.

Anyway, 100 shot is dangerous with a dry (ZEX) kit. You'd want to go with a Direct port kit in that case. HTH, -C

 

Just to add to that, you can blow your **** with a 55 shot if you "don't know what you're doing" or instal it wrong. Whatever you do, check and recheck your connections/bits. -C

 

alright C, i wont talk about anything anymore than, cause I have no experience with the Teg...

btw: you still owe me my entry fee for the track

If you have a GSR do nto waste your time with the ZEX dry shot.
Get the NOS PLATE (direct port) made especially for GS-R. You won't regret it I hear.

BTW...75SHOT = OK for stock internal. Retard the timing and some colder plugs will be needed. 100 SHOT = more fuel.

Once again....NOS D/P PLATE!

 

That's funny, I remembered about that on the drive home. Whenever you want to go, I've got your back! -C

 

don't think so buddy...its NO2 idiot get a brain..nitrous is made up of 1 part nitrogen and 2 parts oxygen...when NO2 enter the combustion chamber the hi temp breaks down the nitrogen and releases the 2 parts oxygen=more air for the fuel to combine with for combustion becuz oxygen is needed to burn more fuel...not nitrogen dumbass....

 

Ok once and for all, nitrous oxide is N2O. Two parts nitrogen, one part oxygen. During the compression stroke the temperature is high enough (above 572°F i think) so that it burns off the nitrogen, creating pure oxygen.

As for using a nitrous kit on a gsr...
Dry kits(and some wet kits) are good up until 75 hp. Once you go above this, kits that inject nitrous through the air intake system/throttle body(even the wet kits that shoot the fuel/nitrous mix through the throttle body) have trouble with getting even distribution of nitrous into each cylinder. this is why they make direct port kits. better yet, in your case NOS makes a plate system that goes between the two pieces of the intake manifold. If you decide to spray over a 75 shot, this is a must. as well as two stage colder spark plugs, higher flow fuel pump, aftermarket ignition, lots of retarded timing, and possibly injectors. the GSR block can handle 100 hp shot stock, but you need to upgrade the fuel and ignition system a bit.

The most important thing in using nitrous, is being smart. Don't over do it by getting trigger happy, trying to add timing to make it faster, lean out the fuel to make it faster, or run too high of a shot just for kicks. Once you do one of those, bye bye motor.

okay
for any chemical questions about nitrous go here
http://www.chm.bris.ac.uk/motm/n2o/n2oc.htm

you'd think that with the wealth of info on the internet that people might look something up before correcting someone

oh yeah, nitrogen doesn't burn, if it did, the earth would explode since the atmosphere is 78% nitrogen

Just make sure you have a fuel pump, I ran 120shot NOS direct port into my stock gsr motor and it was fine motor never blew up....just make sure your fuel and nos mixture is good....

 

here's another link...
http://www.purehonda.com/cool/nos.html

the plate kit injects fuel along with the nitrous, which you stated, but that would eliminate the need for different injectors. The stock ignition system is actually pretty good also. Also, the design of the electrode on the spark plus is more important than having the heat range colder, although that is a must, you can still melt colder range spark plugs if the electrode is not designed right for the application. A general rule for retarding timing was 1-1 1/2 degrees for every 50 shot...(i think thats what it was, i'll have to double check that)

better do some research...or better yet, go inject a gas that is 33% nitrogen and 66% oxygen, and see what happens to your engine...it won't be pretty

save face. try
http://www.google.com/

try typing "N20"

you can save yourself some embarrassment and spare us from pointless bickering of indisputable, cut and dried facts.

 

Good reply mifune. If you guys remember from chem, any two parts of an indentical chemical is going to be prefixed with a di-. So if it was 2 part oxide it would be dioxide. Nitrous dioxide? Please refrain from teaching false info. If your not quite sure, then it is better to make note of that. This is not a flame, just a note that people shouldn't just spit info out. And if you are going to correct someone, please do not discourage them in doing so. We help each other by being polite, who wants to ask a question if they are going to be flamed at>

 

Look at a periodic table and you will see that nitrous oxide is N2O not NO2 or you can call N.O.S. and ask them but I think they will just laugh at you
