Few questions about Nitrous

Question, is it bad to open the bottle whenever you get into your car even if you don't end up using it? and if so, what is the max amount of time the bottle can be left open before anything bad happens? also how much do you have to purge to restore the power boost from "stale" nitrous?

I'm thinking about getting a Zex Nitrous dry kit just because it's the simplest kit to install.. but would a nitrous solution really be a safe addition for my stock(with K&N filter) 91 Accord LX (AT) with 160k miles? It's been well mantained with no engine work done and I believe passed a compression test in the recent past.
I'm also aiming for a 65 shot or 75shot if I can. Could I pull it off with my stock fuel system, injectors and ignition system? Or how much would corresponding upgrade parts cost?
No future mods planned and the nitrous will only be used sparingly for quick boosts when needed.

Thanks for replying!

1. No its no bad to open the bottle even if you don't use it. You can leave it open for quite a while, but its best/safe to close when you exit the vehicle and don't plan on driving for a while.

2. Not very. You'll know when the fresh n2o is in the line. The purge turns from almost clear to white. Takes a matter of maybe a second usually. This depends on the purge valve you get though.

3. ZEX is a great choice since you're just starting out. So long as you're motor in is good owrking order, you should be fine. Nitrous definately won't correct any problems. ZEX kits are designed to work with the stock equipment. You will need to retard your timing & run colder plugs for 65+ shot sizes.

I would suggest you look into a better intake & exhaust as well. They aren't needed but will help you out alot in terms of speed.

Anyhow, ENJOY! Its addicting.....

well u COuld run it on a stock engine....but good luck....u can blow ur rods, pistons, etc after a while...it would be a good investment to do some basic mods.to the ignition and fuel systems... its totally up to u

I ran 75 shot on a stock 98 Civic EX with no internal work. It ran beautifully. Its all about common sense.
Nitrous doesn't blow motors, stupid people do.
