if your gunna use n20 make sure to get a bottle blanket (bottle warmer) and a pressure gauge.
Keeping things consistant is the KEY with nitrous, meaning, always running the same bottle pressure and jet size(s).
I would recommend a wet kit. Dry kits just increase the fuel pressure to deliver more fuel whereas wet kits have both nitrous and fuel jets into the nozzle, dry kits just have a nitrous jet in the nozzle.
With how much extra fuel nitrous engines like IMO dry kits just don't cut it, and with a dry kit if your spraying a 50 shot you'll get like 30 hp. With wet kits you typically get more power and IMO they're safer b/c the solenoid or control box (depending on which brand you use) will take care of the extra fuel all you need to do is put a linear timing retard on for how much nitrous you're using.
The last nitrous car I tuned was a 100 wet shot on a higher compression b20vtec, the instant 100ft/lbs of torque was nice and put him in the 250ft/lbs range. The air/fuel ratio was in the low 11's (11-11.4:1 AFR) and it still wasn't loosing ANY whp/wtq, and I pulled over 10 degrees of timing before the power started to drop (giving away my secrets here....lol)
I personally like nitrous b/c it works in every setup, how well depends on how its setup, what kind of system you're using and the tuning. Use a 50 dry shot and you prolly won't be that impressed. Do it right and you'll love it.
With all of the great tuning solutions available for our hondas nitrous is very easy to setup. With Neptune (my favourite software right now) you can have a secondary fuel/ignition map (with more fuel and less timing) for when you use the nitrous. All you have to do is flick a switch to activate the secondary maps if you set it up to do so in the software, so it can all be done on the fly without having to turn the car off.
Getting setup properly with nitrous can be pretty expensive, but doing it the cheap way can blow engines really easy.
Colder spark plugs are a MUST, less timing is a MUST and more fuel is a MUST.

cool good to see this info I just picked up a zex dry kit on the fence about it
can't you run a dual map on chrome if you use a special socket?
it has a brain so it can keep the bottle pressure constant to a certain point
colder plugs i know are recommended how about the zex sparkplugs the grounding straps are different
I just want a safe setup for abit of extra fun
tuning a must? can it be safe without? retard the timing abit and colder plugs should be good right?

N.O.S. Wet kit all the way!
Ran 13.2 on a D16z6 75 shot b4 it poped a rod.
Ran a 50 shot on a D15bvtec ALL THE TIME for 40k... NO PROBLEMS...
Much like boost... Nitrous is not based on how much of a "shot" u can run.
Just like boost.... ppl say will my car handle 10lbs of boost on a D16z6... lets see.... if it maked 220whp or less and tunned well with a healthy motor yes... otherwise odds are "no" on a "stock" motor.
So for Nitrous it all depends on the condition of your motor, the tunning and overall knowledge.
Like Zeeman said " colder spark plugs, more fuel, less timing are all a must "
I have seen b16's stock push 150shot for giggamiles.
Mostly range from 65-100shot though.
B18c's if its healthy and u do it right... go for a 85shot. (Start small though, 50,60,65,75,85 ) See where ur limits are.
And change plugs all the time! On all my motors I changed the plugs after every pass!
*Note : If your motor has any issues, like burning oil, leaking oil etc.... expect it to get really BAD once u start spraying. If your motor is healthy and u do it smart 50-75ish+/-
u can be spraying for giggamiles! *
