"Don't be afraid of Nitrous. Properly used,it is great. Abuse it and you will be walking home with a blown motor.
Learn all that you can before getting a kit,some people should use something other than Nitrous to attain their goals.
Read the manual carefully when you buy a kit.
Fuel is the most important commodity in your engine,make sure you have enough.
Make sure your ignition system is strong.
Make sure you set the timing to the reccommended settings as stated by the Nitrous kit manufacturer.
Find a place local to you that offers Nitrous refills for a fair price.
Get the proper permits in order to use Nitrous Oxide in your car.
Since Nitrous will make your car go faster in the quarter mile,you must gear the car for Nitrous use,not for the motor only.
Enjoy yourself." I couldnt have said it any better, so I quoted it.
