Nitrous On H22A

[jimbo34]

Hey guys I have a very open question. Would running a 50 shot of nitrous on my jdm h22a be semi safe with stock internals. im under 60k miles. Im about to do a compresstion checkto make sure. I would also get the wide open throttle switch and other safty things. Dont wanna blow up!

thanks

You can do up to 100-125 wet shot on an H22 safely

Safely is a pretty vague term. If you're going to be spraying something like that daily without supporting mods you're looking for trouble. I think this guy is just looking to bolt on a nitrous kit and have some fun. In which case a 50 shot is more than enough. Anymore than that and you're going to have to look at upgrading your fuel system. It also depends on what kind of mods he already has done.

To the OP, we really need your exact set up to help you out further.

Most of the nitrous manufacturers say you can spray a 50 shot on a bone stock motor with no worries and no mods. A 75 shot means 1 or 2 step colder plugs and you can retard timing a degree or two, but don't really need to with the colder plugs, 100 shot requires colder plugs and definitely a timing retard. I would suggest going to a wet kit if you decide to run n2o, it's not much more expensive, and it adds in the extra fuel required for the shot you have installed. They also say you don't want to spray more than 50% of your horsepower. So a 100 shot on a good H22 would be about the limit without building it to take more abuse.

Look in the nitrous section stickies, there's good info there.

Blah not many supporting mods required, it's pretty straight forward. If you have common sense you can do all the "supporting mods" to run a 100shot in about 2 hours.

Thanks for the info so far, I'm new to nitrous and have been reading a lot on here.

I'm definitely only running a 50 shot and not using it very often. So you guys think wet shot all the way? I kinda wanted to hide it best I could. for the timing, i set it right to 0? don't advance it if your running noz right?

Any other tips for this project?

- supertech valvesprings an retainers
- arp head studs
- arp rod bolts
- type s pistons

Safe and reliably, or holds it but risky? If I was sure of my build, I'd hit it with a 125 wet shot and feel pretty safe about it. But: I myself would have to have done the build. I'd hate to lose an engine because someone else was having a bad day or missed a bolt somewhere.

I did the build myself. Hell, it's still sitting on the engine stand. I've been wanting to throw some nitrous since my last car with the h23 in it.

I guess Ima get it on the road and get a good tune, just drive it for a while.. If I still want to go nitrous after I see how she runs, then I will.

Does anybody have a part number for said spark plugs? I'm pretty sure everyone prefers NGK. But what am I looking for on the box?

[RICHIE*GT35R]

I'll go with a 75 shot all day long!!!

You can do up to 100-125 wet shot on an H22 safely

this is SO wrong.


safe numbers of shots are 35- MAX 100.

with stock internals of ANY bone stock car.

do a 50 to 75 shot, its safe, and the power you want is there.

a 100 shot can be safe but its risky for a number of reasons.
thats a lot of nitrous.
your bottom end is taking the punishment.
with a shot that high you HAVE to make sure its installed correctly.
start thinking about beefing up your fuel system

ANYTHING over a 100 shot is possible. but dont expect your motor to last very long. If your wanting any thing over 100 shot your really heading into nitrous being your main forced induction. and you should start thinking about building your block and head to hold together and like said before your fuel system needs upgrading and also little tweeks to your tranny.

if you want a weekend warrior that is just a play toy do a 50 shot.

if you have lots of money do a 100 shot and buy new piston rings every other week.

if your like me and most in love with the rush a big shot will give, build a block and spray a 125 shot on weekends and when at the track, up her to 200!

zex makes cold nitrous spark plugs and they only 25$ for all 4
