Okay, as an avid nitrous user, and having many friends w/ turbo setups on their cars, i must stand up for nitrous. Also, I recommend ZEX, then NX. Venom is just WAY overpriced, i've heard NOS to be very unsafe, and I don't think i'd trust any of these companies that just sort of hopped on the bandwagon like "Nitrous Works"....

Nitrous Pros: Adjustable amount of horsepower, WAY cheaper, less time to install, very safe & reliable if tuned right, cheap to refill bottle, ability to turn it off for daily driving, very safe so long as you take certain measures such as a blow down tube & pressure release valve.

Nitrous Cons: If it's cold outside & you don't have a bottle heater, you're not getting nearly the bottle pressure you want, i.e., not nearly the boost you should be getting.

Turbo Cons (from what i've seen):Very expensive for all parts needed, extensive downtime for install, many parts need to be custom fabricated, constant tuning, rediculous amount of oil consumption (this prettymuch makes up for the cost of refilling your nitrous bottle if you're running a decent oil)

Turbo Pros: Bragging rights (fmic, bov sound, etc.)
