Re: Bottles are for babies.
Another way to go would be to build your own Nitrous Fogger system. It's different from Direct Port Injection in the way that with the 280 (Or any EFI ZCar) you'd have to drill holes in your Intake. With a fogger system, on an EFI car, you can just get a fogger nozzle, and rig it up right before your throttle body. Nitrous Oxide isn't dangerous if you know what you're doing. I've seen ricers blow their lids at the track, and i've seen some do well. But, with a 280, it's easy and a cheap way for HP. I'm actually designing my own Nitrous system. I've designed a few, one for my friends '93 accord with a H22A engine (2200cc (2.2L) DOHC Vtec) from a '00 Prelude. That was the hardest. But he's got the fastest 4-Door accord around.

hehe
If you think about it, all you'll need is a bottle, a solenoid, tubing, a fogger nozzle, and maybe a bottle heater if you want consistent times. I'm just building mine for fun, and the fact that I can get one done for about $120 compared to the ZeX systems Nitrous systems $539.
Think about it. If you want serious HP, and track times that'll blow the **** out of the ricers, then go Turbo and pimp out the engine. But if you just wanna have fun like me, build a cheap Nitrous system.
and don't ever call is NOS. EVER. It's Nitrous Oxide.
Enjoy.
