i went racing with some friends last night out in the farm country around my town? and a couple of my friends are running nos on their cavaliers and one of them last night tore up his engine and tranny when he tried to use his nos system. and i was wandering how much nos could safely be put on my d16y7 with out causing damage to it, i have over100,000 miles on it. i am hoping to swap out the engine in july with the y8, so if i do blow the engine it will not be that big a deal, but i would like to use the system on the y8 also.

Eh i wouldnt use more than a 50 shot... unless you have other mods?

upgrade fuel pump/injectors you could safely run a 75 shot, stock everything i wouldent run over a 65

what do you mean by other mods? and how are "shots" rated is it by the nozzle size? also how hard is it to install a nos system and which is the best i have been thinking a bout using a ZEX system. has nebody else used this system?

ide go with a zex kit, yes its rated by nozzle size, zex is probably the easiest kit to hook up, i mean if you have common knowledge it shouldent be that hard for you, but if your really clueless you should let someone do it right so you dont fuk anything up

unless you wanna mod it up dont go over a 50 shot

on a stock motor if it is done right timeing retarded and all i would be hesitent to run a 50 shot

if mods it up i would ru a 50 shot are running NOS

How much nitrous do you guys think I can safely use, I have a 99 civic si engine with aem cai, apexi exhaust, and dc sports header with a act stage 2 clutch??

none ... safely used or not nos reduces the life of your engine.

I ran the 55, 65 and 75 horse shots on my stock D16, right now im building a bottom end for my hatch...but ill probaly still run just the 75 horse shot....

dont use the NOS just chuck a turbo on instead simple :p

dont use the NOS just chuck a turbo on instead simple nitrous would be simpler to put on and it would cost way less for the same if not more power, sure its not continuous power but its there when you need it

I don't know all the facts, but has anyone considerd that this guy blew his engine cause it was a domestic? I was under the assumption that domestics do not handle nitrous or forced induction very well.

hey civicHBsi91, i usually agree with you but not on this one. there is no way you can stand here and tell me that nos can put out more power then a tubrocharged setup. lets say you take 2 engines, both built for their applications, which are nos and turbo. which means both of them have lower compression, upgraded fuel, and ignition. and now you say that the nitroed engine can have more power? first of all a built nitrous engine runs like crap without the nitrous. because the compression is lowered and there is nothing to boost it until you squeeze your nos. the turbo is always there and never needs to be refilled. not to mention that on stock engines, nitrous actually does more damage then a turbo would if they were both used properly. plus turbos can add almost any amount of hp to any engine but ive never heard of a nos system injecting more then a 350 shot.

very true i would pick pick turbo over NOS ANYDAY

What the man was trying to say was that turbo's are hella more expensive, and hp for your dollar nos is the best. I'll probably get a zex setup, but I am defenetly getting a head swap and replacing with high compression pistons and cams before. Also, a 350 shot of nos would be insane, but they do make them

ed yes thats true but i what i said was meant for like stock internals and all, if you throw on a turbo on a d16 and run say like 5 or 6psi with stock everything except fuel components youll put out like 150-180 lets say and nitrous with a 75 shot you would put out the same or more and its cheaper by far and you wouldent have to wait for the turbo to spool, but fully built engines for both turbo would probably come out on top like you said, but for what this guy wants...would you go spend 2,500 + or like 650.....

Get the fmax kit and run way more boost on stock internals....

yah man even on stock internals you can run up to 10 psi with the stock fuel and ignition which would be much more power then you could squeeze into a d16.

no actually we just had another discussion about the same thing in the forced induction forum. the d16 can actually handle 15 psi on stock internals but of course with upgraded fuel. some guys was running 20 psi putting 300hp to the wheels on stock internals and he kept it at 16psi i think for over a year. but at 8 psi it would be very reliable and the stock fuel system is good enough to handle it.
