If you are thinking of getting a camaro - what trim what engine would you like - if you are looking at an 98+ LS1 it will be significantly faster then anything you have listed as cars you have driven. I would learn how to handle that power and learn about the LS1 itself before i went on to nitrous. I myself think nitrous is great but it is not something you want to just buy slap on and use. You want to know what kind of kit best suits your vehicle, your fuel pressure, how much the engine can handle, probably will want colder plugs, might want to retard timing, learn what a purge, bottle heater, fuel pressure saftey switch, rpm window switch, and other various nitrous components that you would want to add to the kit are and what they do. stuff like that. I know most big nitrous companies have an FAQ you might want to visit those sites and check those out. I now nitrous express has one. If you are serious about buying a LS1 and using nitrous might want to check out the GM tech forum here and then check out other ls1 forums

basically do your own research, lose your sig and ask intelligent questions after you do your research and you wil be fine. I have used over 320 lbs of nitrous in my car and have yet to run into any problems

good luck
