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

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.

what did i just said for high shots of nitrous not low shots.

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

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.
