Alright me and my friend were discussing whether or not I could run a small shot of nitrous on my corsica. 2.2 liter,possibly a 75 shot?..anyway whats the smallest amount of nitrous they make..and would i have to make any other changes or could i just hook it up and use it once and awhile?

..anyway whats the smallest amount of nitrous they make..
You can buy empty nitrous bottles.

The basic rule is not to use more than a 100 shot into a stock engine. But you have to take into consideration the age/condition of the car before running nitrous. Older engines won't last through too many shots of N2O.

with a metering style NOS system, you can run .001 hp shots if you really want....

the size of the shot is purely controlled by the jet size, or the pulse width of the solenoids, depending on the type of system.

Its important to make sure the system is tuned properly. A 50 shot can and will blow up a motor if you don't tune it.

Well i should of told you guys that the motor has about 155,xxx on it...
