Stock ECU on stock timing don't run too big of a shot. Im running a .038 jet and my plugs look fine. I've been thinking of running a .040 or a .041 jet. Im gonna hook up my friends wideband before I do that. A few people have been running the .041 jets with no problems, but they also haven't been heating up their bottles for more pressure.

Stock internals are good for alot more than you probably want to go. Theres a guy who went to a turbo setup who was running a 125 direct port shot with an AEM EMS for a while. He dyno'd 335whp.

GET RID OF THE OEM DOUBLE PLATINUM PLUGS FOR NITROUS. Nitrous and platinum plugs don't mix well because platinums heat up too much since they're self cleaning. It'll be more prone to detonation. I'd suggest going with NGK 7173 plugs. They're cheap copper plugs that work great. Gap them at about .035ish. Swap out the plugs after about every 20lbs of nitrous or about 3-4k miles if you're spraying.

If you're going wet, get a window switch for sure. Set it up so you don't spray before 4,000rpms and you don't spray over 8,900rpms.

I won't rant about my feelings about wet vs dry. Too many uninformed people and too many arguments from it.

If you have anymore questions, post them up and I can help you.

Im still on my stock fuel pump. If I go higher than a 75 shot, I will upgrade it.

.038 and .040 are jet sizes. The bigger the number, the more nitrous will flow for more horsepower. I call my .038 a 70 flywheel shot. Its probably 55-60whp. A .041 jet would be a 75whp shot.

I prefer dry. Let the fuel system take care of the fuel. You won't be pushing the stock system by any means with what I am running. Honda intakes pool up easier than most I've seen. I've seen a couple of B16s on 100 wet shots pool into the intake and have a backfire while testing on the dyno at 7k rpms. Wet kits usually have a small lean spike. Unless you're running a higher shot, the spike will be safe though.

If you go dry, you will need a kit that boosts fuel pressure when you spray so the car knows to add more fuel. This is the concept that most people who are weary about dry kits don't get. Only a couple of companies make kits that do this. Either the NOS 05120 kit or the Edelbrock 71000 kit are my recommendations. Zex makes a dry kit that does this and is easier to install, but I don't recommend it.
http://holley.com/05120NOS.asp-I got mine for 500. Don't know how its advertised as 739.?
http://www.edelbrock.com/sportcompac...univ_dry.shtml

To be perfectly honest, if you're just gonna run up to a 75 shot, wet or dry will work fine. Just with wet, you need the 80 dollar window switch moreso IMO. Many places will try to charge you more for a vehicle specific wet kit. In reality, for all 4 and 6 cylinder kits, its the same thing with different jets. So if you're going wet, a universal 4 cylinder kit will work fine.

I would suggest either a NOS sniper wet kit(same as the regular, just cheapened down a little bit. Its just as safe.)
http://holley.com/07005NOS.asp-NOS must jack up prices on their website cause it should be cheaper than whats advertised
Or a Dynotune wet kit
http://www.dynotunenitrous.com/store...?idproduct=100

Here's some links for more info:

Info on the NOS dry kit which I have. The guy running it hasn't updated it in a while and isn't finished.

thats some really good info! This should be a sticky for sure.

Def. read up on everything before you get started. Nitrous is only dangerous when it is in the hands of the unlearned.

a well set up system can maintain reliablility while having nice push button power.

The way I see it, any form of forced induction can be harmful if it's not set up right and your engine isn't stout enough to handle it. As long as you know what you're doing, I don't see why nitrous would be any more dangerous than any other form of forced induction.

up to 80 shot with stock mapping. Make it a little richer the higher the shot you run. after you get some afr's or dyno time you can lean it a little. I like direct port better than the single nozzle.

Differences between wet n dry

I dont really know anything about nitrous, except that you push a button and you go faster. So what are the differences between a wet system and a dry system?

Lay it out, what are the pros and cons for each system. Not looking for argument or anything, just the facts. If you want to give an opinion on which is better, im fine with it, just state why and give some facts to back it up.

Thanks.

dry: nitrous nozzles only - additional fuel is delivered via the stock fuel system, usually by upping fuel pressure at the fuel pressure regulator

wet: nitrous and fuel nozzles - additional fuel is delivered via nozzles connected to solenoids that usually feed off of the stock fuel rail.

so what are the benifits? Is one less labor intensive for installation? Is one "safer" to use, with respect to damaging the engine? Or are the end results going to be the same?

What would you use turbosix?

you dont need a wet kit at safe hp levels on s2000s... dry kit hooked up to the fuel pressure regulator is sufficient.

Not to sound like an ***, but running 9's in the 1/8th on either a 75 or 100 shot is garbage. Thats equivalent to a 14 second run if you're bench racing.

You're getting knock retard. WHY DOES NO ONE BELIEVE ME? FUDGE!!!!

I run consistend 8.5's in the 1/8th on all season tires with a .038 nitrous jet.
http://www.dragtimes.com/Honda-S2000...lip-18129.html

OMG I WONDER WHY I RUN FASTER? IT CAN'T BE BECAUSE YOU GET KNOCK RETARD, CAN IT?

Also learn to launch without wheel hop. You won't bust axles.

Again. Sorry, but its very very very very frustrating when people brag to me about running a 100 shot or something bigger than what I recommend which is what I've tested at the track to be accurate. A .038 nitrous jet.

Just because you can, doesn't mean you should.

disclaimer........if u learn how to read it says that on the first two passes no nos was used....meaning i didnt spray.....im supposed to hit 8.9 no nos....due to wheel hope and a 2nd missed gear i didnt hit 8s.....

I have a 2000 Honda S2000 and I am looking to put Nitrous in my car. every thing is stock except i have a air intake and a ACT stage 2 clutch. I was wondering if I should put wet or dry and what the adv and disavd are to them. i am thinking of putting 75 shot. Is that to much. I am just looking for some input on what i should do. i am looking at a kit on Nitrous express.
thanks

I still want to hook it up but I'm afraid of damage to the motor(85k), ZEX sounds like the way to go! If done right.

yes, it will be fine. if you are not using the nitrous the bottle valve will be closed and the car will drive 100% stock. to activate the system you would need to open the trunk and open the bottle valve, then activate the arming switch. once its armed you have a throttle switch so once you go WOT the nitrous is activated.

its not like in the movies where you press a button on the steering wheel (though it could be set up that way with some extra wiring..)

perfect, you can open the bottle when you get to the track. one less thing to wire up and more importantly one less thing to break.
