what should i do before nitrous?????

[purespeed187]

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

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.

[Coolstr85]

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 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 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
