what should i do before nitrous?????

hi i own a 95 integra gsr and i want to put nitrous in it. I was wondering if it was ok if i just went and put the nitrous in my stock car. will it be good? im putting new sparkplaugs fuel injsectors and fuel filter in my car first so i think thats all ill need. oh yeah its only a 50 shot nothing big.

well for one make sure the new spark plugs are not platinum- i recomend iridium- second a 50 shot should theoretically be ok on stock internals. i'm more conservative and i would say don't go over 30 shot. But remember Nitrous is hard on the engine you can blw it up even with small shots.


To get really big shots of nitrous you have to rebuild the bottom end.

You should be fine with a 50hp shot. Is it a wet kit or dry kit? Have you done any bolt-ons?

Remember, it's not the nitrous that blows up the engine, it's the tuner. If you crash your car, is it Acura's fault? Before nitrous, I would recommend getting an air/fuel ratio gauge to make sure your engine is runnig in god condition, if you know it's running bad with the nitrous engaged, you can shut it off and save your engine right? Gauges=good idea.

My bro uses NGK plugs in his 50 shot 95 gsr, they work fine, he melted the bosch ones after the second day of squeezing.

Gauges, read up on nitrous tuning, make sure your injectors or fuel pump can keep up with the air, that's ll the advice I have for you now....

Happy Hunting ;)

Fifteens dead ahead!

ahh more like 14s dead ahead

now i have a question about this as well..im building up my D-series engien to be different. but currently ive been working on more show.(i got them switches.) but anyways. my question is this..as long as i upgrade my spark and fuel, and keep an eye on my air/fuel gauge, could i safely shoot a 50 shot on a d16y8? if not, what parts do u suggest i upgrade before that?

Is that the vtec one? you could possibly be safe, but d16's have very weak rods. I heard they break at 200 engine hp, but I broke mine at 135 wheel hp! I was roadracing, 15 minutes reving= no more d16 rods :(

I would do 35-40 just to start out, if the coast is clear, go for 50, better to be safe than sorry, or in this case... broken rods.

yea my engine has VTEC. so the rods are weak? so that means new rods, and i might as well replace the pistons while im at it..should i get a block guard or anything?

D16 is a vtec engine? i thought only b16 were vtec? or is the b16 with performance vtec like the k20 in the rsx type s VS the k20 with woosy vtec in the new si?

Silly boys with toys, if you believe your stock engine will survive one shot of nitro, you got your mouth wrapped around your tailpipe cause you're smoking something. No it won't last and anyone that says otherwise just want to see you blow your engine:bloated: do me a favor and take auto tech class.

first it depends on engine. Some are weaker than others.

Second it matters how big of a shot is. i personally advocate a 30 shot on average on stock engines.

Third it matters how the nitrous is installed. If its a crappy job you'll run lean. A proper job will have you run with a perfect air/fuel.


So if you do a proper job you'll be able to run with nitrous on a stock engine. Plenty of people did it. Ask self if you don't believe me.

Self has a Chevy, they're like a rock.
"purespeed" will have to at least rebuild the engine, you're not breaking the speed record in a car with 100,000 miles! The rigs will go for sure. "purespeed" doesn't seem like a tech geek that can handle this type of tuning.

Definitely depends on the engine. The only engine's I have personally run nitrous on have been Chevy's(LT1s mostly). I do have friends with I4s though who have ran nitrous on completely stock engines and had no problems that I know of. Not that big of a shot, nothing more than a 60 or so but still. My friend Tac was running a 75hp shot on his GSR with no problems for about 3 months. But IMO a 75 shot on that engine is definitely pushing it. I say if you stay down around 50hp or so you shouldn't have too many problems. As for my own engine, you're right, it's a rock:D 250hp shots on a mostly stock engine(new rods, stock pistons and crank). Rods are the weak point in my motor like most.

Like I said, I don't have too much personal experience running n2o on Honda/Acura's...BUT...I would think that with the right fuel setup you could run a pretty big shot(say 125hp or so) with no problems. That's the key to my setup. Almost $3500 on the fuel system alone. Could have easily dumped that money into a forged rebuild or even forged stroker rebuild. I just wanted to be able to say I did it on stock internals. Which I didn't even completely accomplish(damn bastard rods:finger:) but I came pretty close. So I would think you could do something similar on a smaller engine. Obviously not as big of a shot, but maybe something proportionately as big. It's all in how much money you want to pour into it, and how much risk you're willing to take.

im lookin to put like $5,000 or less if possible into the build. thats not including the cost of the nitrous/other boltons ill need. I know that a stock civic SOHC d16y8 wont be able to handle a big shot of nitrous, thats why im asking, what do i need to buy to strengthen the engine so i can safely shoot a 50 shot. i know most of u are gonna say "swap that thing" but thats just it, everyone, and i mean everyone in atlanta with a show civic has done a swap. its boring now. there are 5 modded civics at my school. 4 of them have swaps, 1s engine is totally stock so he doesnt even count. i dont wanna be like the 4 other guys, i want to be the single overhead cam bad a$$. so i can have my little d16y8 and still hang with their NA b16s

ok to rebuild for forced induction this is what to need to do--->blueprint and balance the crankshaft
get new rods, new pistons, resleve, and lower the compresion to about 8.8:1

Compression does'nt need to be lowered for nitrous, you're getting it confused with turbo. You can have the highest compression you want but you have to keep an eye on the air/fuel gauge.

ok, i don't think that those 4 guys with civics swap just for the fun of it. There's a reason. They have better engines now. And if they have nitrous, well then more power to them. Its safer and probably more common to swap it then add a shot of nos. If you're gonna go mess with nitrous with your stock engine (btw, i got the same engine and won't add a bottle till i swap the engine) then it can be done and shows some effort or hard work, but just make sure that you play it safe and be a little more conservative.

yea i know they are stronger and better engines. but i dont wanna be just like all the rest of the people at school..it was cool way back in the day when people just started doing swaps..now its liek every car at the local shows has an engine swap

What the heck are you talkin about??? I'm the first one to put a b16 in a 93 civic ... J/K :D

i did some reaserch i found out that i was right after all. for high shots of nitrous you do need to lower the compression.

You don't really have to lower compression for N20. But the key for big shots is forged pistons and the right tunning. Unless you are talking about 250hp shots and bigger the compression can stay stock unless you have 10.2 or higher. It's not like turbo where you have hot air being forced into the cylinders, so there is less possiblity for det. But propert tunning is an abosolute must for nitrous, running it lean one time with a fairly big shot will retire the motor! If you don't feel you are capable of tunning the nitrous then have a shop do it and don't change it.

How many ppl with hondas do you know that are squeezing 250+ shots on a car that they drive daily or on the street at least?
If it was a purpose built drag car the the higher compression would not matter b/c with shots like that on honda motors you will be tearing it down and rebiulding every so often.

why are you arguing with me. i don't care how many people run on honda's 250 shots the truth is with very high shots you need to lower the compresion. i was just stating a fact. i did not even mention a honda in my post.

In case you have not noticed this is the HONDA/ACURA forum. And the original question was pertaining to a HONDA. There for what I said appies to honda he did not ask about a camero or anything.

uhh n20 has the same effects that turbocharging does on engines. you say you dont have to lower compression just tune it right and watch the air fuel guage. well the same goes with turbos. you dont "need" to lower the compression on a turbo motor but people do. why? its called detonation. without jet fuel you can not run high boost or a good shot of nos without an insane engine management system. but if you do have a stand alone and tune it correctly you can run 20 psi on stock compression. but thats putting it on the brink of detonation which most people dont want for street engines. thats why you lower the compression. anything over a 75 shot should have its compression lowered at least a little bit unless you like chancing your engine.

but why even go for nos? its such a bullsh*t way of making power. how gay is it that you roll around with your car slow as a snail all the time until you use nos. not to mention the damage it does to your engine. why would you only want power some of the time? why do you want to have to pay 50 bucks to fill your tank everytime you use it up? why pay to fix up your engine enough to turbocharge it but only use nos? NOS IS GAY!!!

if you have a turbo and only use nos to cool your intercooler or spool the turbo faster then youre a pimp. otherwise f*ck nos.

thank you ed for explaining it to him.


and whtteg thank if you haven't noticed this is the only place dedicated on forum to forced induction making it the de-facto posting place for all the forced induction questions pertaining to any car. And again all i did was state a fact i have no ideea why the heck you just have to argue with me.

Nitrous is gay?? If you strap on a nitrous kit on your stock 4 cylinder and call it a day then I SOMEWHAT agree that it's a little bit "gay". But I run a nitrous setup on my Z28 and resent the fact you're calling me "gay". My motor has no problems making power ALL of the time, and I run an 11 second quarter mile NA. I run a 250hp shot and it pushes my car to low 10s. I hardly think that is ghey, and I challenge you to find a car that runs as well as mine with stock pistons and crank on a daily basis. I also challenge you to make the power I do with a turbocharger. Not to say it can't be done, because it definitely can and I have friends who have done it, but it's not an easy task by any means. And you never have to pay $50 to fill up your tank after one use. Unless you're running a 10lb bottle and a 1000hp shot:rolleyes:

i believe he was mostly refering to using nitrous on 4 bangers. on small engiens nitrous is a very inefficient way to raise hp.


you must remember that nitrous was orriginally designed to run on muscle cars.

Also, I would like to point out that we don't have any other forced induction forum here at AF. So some people use this one to talk about other vehicles than Honda/Acura.

Neutrino and edman24 have stated everything that I would have said and I agree with them fully.

That is like saying turbo's were originaly designed for small displacement engines. Well a lingenfelter vette has great success with it. If nitrous is gay then why do all of the top drag racers use it? And why do you say it is a inefficient way of producing power? With nitrous you can save money on gas and not be tempted to get a ticket for street racing as easily as if you have a turbo and it wastes gas driving every day and has the power on hand to get you in trouble. The nitrous is more efficient than a turbo anyway because you have the power with out turbo lag.

How is it inefficient? I'd say that aw 75hp shot on a 4 cylinder is a very nice gain. About what a turbo will give you with stock internals. That pushes Preludes close to 300 engine horsepower, for a low price(low in comparison anyways:D)

well turbos got a very long way since they wre designed. Also i say that high shots of nitrous will cost you a lot because it cost over 3 $ per puind to fill it up. That can lead to a lot of money. Also turbo engines are not gas guslers they consume like na engines unless you push them. if you don't belive me ask polygon.

my poit is that in the log run the nitrous will prove very expensive since it cost so much to refill.

You go ahead and lower your compression while I run my 10.0:1 compression and shoot 50 in a healthy manner ;)

this "research", where did you find out that info?

This "research", what is the source? You never know until you test. Lowering the compression helps, but it's not required.

since when a 50 shot is a high shot:confused:


and about reasearch a guy that knows a guy.....you know how it goes:D


just J/k

OK fine... 100 shot, you can still have a 10.0:1 compression, as long as you're careful about your fuel supply.

yes i was talking about 4 cylinder cars because i swear i thought this was a honda forum. but maybe im mistaken:bloated: anyways i could care less about how fast your z28 runs on a 250 shot. nothing you say could convince me that nos is a good idea. not to mention the fact i dont like american cars anyways. american philosophy has always been "you want more power? make it bigger!" this to me is complete bs. your z28 is an exercise in the stupidity of american car company engineers because they choose not to use the technology they have to tune their cars. they only look into cost effectiveness and how much money they can make by cutting corners. i cant stand that. america could produce the best cars in the world but they dont because they choose quantity over quality.

in no way was i directing an attack towards you or your car. i am attacking the engineers who designed it. so dont take it to the butt and start a piss fest. and to those of you who think that nos is a godsent then go ahead! stop crying about it and use your nos. ill just race you until your bottle runs out. then what? "oh hey man i got to go fill up, can you wait a minute?" yah sure buddy.

and you guys talk about oh 75hp is a good gain on any engine. yah it is. but it does you no good when it only works for a few seconds. no one i know who had nos, has kept it longer then a few months due to engine failure or they just got sick of refilling. whether you choose to admit it, without a properly built engine your engine (honda engine!!!!!) you will encounter problems with nos. you might not detonate, you might not melt a piston, but your pistons rings are taking a nasty beating everytime you use it. but hey, its not my engine so what do i care?

and why do all the top drag racers use it? like who? and which ones use it as a main source of engine power? NONE!!! they may use it to cool intake temps or spool the turbo, but none of them just run nos. at least not if theyre to be competitive.

oh and i do know a guy that could kill your z28 whose running stock internals. and its a six cylinder. a turbocharged 3.2 liter bmw engine that would make your z28 look like a pinto. anything else?

I didn't say my car was unbeatable...But if you want to do things that way...I know a guy that could kill your 3.2L turbo. Michael Collington and his LS6 with a 750hp shot. Anything else? But as far as the rest of what you said that's all fine and good. I don't take anything as a personal attack, no harm done. I have my views and you have yours:) But when it's all said and done, who's faster???:D J/K

The use of nitrous oxide (N20) 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. It was never intended or produced to be used in cars.

I have heard about that somewhere else also, but it is now in cars and the R&D has come a long way. I don't undrstand why ppl hate N2O so bad. You can ride around with no lag or anything all day every day and then when you want to race you can use it.

Peeps were using it to cheat... They went to alot of trouble to hide it, so that way they could win $$$$$ while street racing... hehehehe

I "think" it was in the vary late 60's or early 70's, when it was occuring. Ever since then it has been given a bad rap because of that...

"Noth'in like Induction..." ;)

NOS IS GAY!!! its freakin called NITROUS! N2O!

has anyone checked out the zex site where they ran what 13's i think with their basically stock d16 powered hatch with nitrous and some slicks and i forget what their crx runs but its also a d series.....i plan on using nitrous, i used to hate it cuz i thought it was cheating but i see now its just like a turbo or sc or anything of that nature

Exactly what we were tring to tell ppl.
