i have an H22A that i am putting in my integra. i know that the H22's are nitrous friendly, so plan on basically all motor, and spray on the track. does anyone that has a prelude have nitrous on it, and if so how big of a shot, wet or dry, preferably on bone stock motor. i want to know what it will hold from the factory, and what it can hold without going inside of the motor.

 

I've seen a few direct-port 100 shots on the stock motor - which I think would be ok as long as you only spray a few runs on the track every now and then.

 

I've done a bunch of research and bought the following for my '01 SH

NX WET single nozzle kit (safe up to 75 shot)
NX Purge Kit (a must)
NX Bottle Heater (also a must)

1 step colder plugs

no timing retard necessary up to a 75 shot

just don't get greedy and go to preludeonline.com they've got some guys that know a hole lot about Nitrous.

He said "Greedy"

 

There are several 5th gen ludes runnin 75 shots with 1-2 step colder plugs, and 1-2 degree timing retard for the 75 shot.

 

i have heard it is possible to run 100 shot bone stock, if you upgrade fuel stuff, it is safe. and i was just getting some other opinions. thanks, and any other info would be great.

Im not sure about 100 shot on stock internals. Even with fuel and an ignition upgrade it still sounds a little risky. I would say a 75 shot with a fuel and ignition upgrade and you should be safe.

 

i would be sared to go anywhere over 75 shot without touching the internals. just to stay safe, stay at, or belo, a 75 shot.

 

Wasent there a post about a guy that was running 75shot on stock and everything ran great for 2 years, then boomb at the track one day. /shrug I guess it's safe for a while anyway.

 

I deffinately would NOT run a 100 shot on stock internals. It might be alright for a little while but I guaruntee you it wont last too long. Do a 75 shot with 1-2 step colder plugs and retard your timing 1-2 degrees and you will be fine.

 

My firend is running a 100 shot direct port system on his h22a powered civic. He has 100% stock internals and the car is still is running strong without any problems. But he also has a msd ignition system, blaster 2 coil and 1 step colder plugs besides his i/h/e combo.

 

The question is how many have been running 75shot for over 2 years and never had a problem? Shure it's running fine now, but can it last more than 2 or 3 years like that?

So you've run a 100 shot on a stock H22 and blew it up?

I've been running a 75 shot for one season so far. I won't recommend doing anything higher than that, although personally I'm going to put in the 100 shot jets once I get everything sorted out in my car. I also don't care if I blow the thing up either.
I like wet kits(preferably direct port) because they allow the most precise tuning and you don't have to rely on the inectors and fpr to get enough fuel into the motor.
Also, motors just don't blow up after two years of running nitrous. Something had to cause it or it was a gradual loss of compression that the owner never bothered to check. If you don't have the fuel there when you spray your motor will pop. The trick to nitrous is to check your car out before you spray. Check the plugs, the filters, the fuel pressure, the nitrous pressure, compression, etc. We haven't had a single engine blow on PO.com from nitrous since I've started moderating there. Do the **** right and it's as safe as anything else.

 

Man using nitrous is all about the amount of tuning and atention to detail you want to pay. Nitrous is only blowing peoples **** up because they think that every 50 year old guy in a corvette is gonna race them and by the time were they reall ywant the performance to prove some power and not be a **** they blow there **** up. That and the fact that alot of people are still using the "hit the button" method rather than using a WOT method (which is the way to go!) Also people shoot it dry into there intake and most of the nitrous goes into the 1st and third cylinder maybe (correct me if that isnt correct) and end up blowin up those pistons or burning them or whatever! Have you ever seen a piston that was fucked from nitrous? Wow no more sides to the indintions on the top!!! it just kinda gets to hot and melts them! Anything is safe with enough knowlage and know-how. If you want NOS go for it. if your engine is stock, dont go bigger than 75 and pay attention. My personal advice is, im all about the gauges! You gotta know what the **** is really going on in the engine and to get that information you need gauges! Hope o helped!
I got a friend with a built SR20DET (Silvia) with a single turbo in a 3rd gen RX-7! he went to track not to long ago and ran 22 lbs. of boost and decided to do the fifty shot of nos in his trunk for power before spool had built up. He blew his head gasket, BUT put down an 11.4 on slicks.!!!!!!!!!! do you have the ***** for nitrous i guess is the real question?

time for

 

laughin and others, thanks for your advice. after ghosting here and on PO for quite some time, i think i am finally ready for my buildup.

I own a 93 VTEC which is in storage right now. Before I purchase the NXL Nozzle system, i am obviously going to run a compression check. If the results come back less then satisfactory, i am going to immediatley rebuild with type s pistons and forged rods.

I am young, and I am (unfortunatley) not made out of money. Anyways, my question is: How big of a shot do you think i can spray with type s pistons and forged rods? Forged pistons and sleeving will break me, so i want to see how much this setup will hold. 100? 125? more?

I will have an msd digital 6 ignition, dyno tuned hondata or a vafc, as well as a beefed up fuel system. Will i need a new fuel pump to handle over a 75 shot?

 

You'll need a new fuel pump for anythin over a 75 shot and you'll need an fpr to control all of that fuel. Lightning has some nice Walboro 255lph pumps for sale. The type S pistons aren't anything special, so I still won't recommend anything over a 75 shot although I'd take it to a 100 shot. Like you said, you aren't made of money, so I'd plan on sticking with the 75 shot for a while. Get use to running nitrous on your car before you go slapping a 100 shot on it. You may find that a 75 shot and some practice will give you the ETs that you want.
