Yes you can, but on a mostly stock car, it's a good way to blow your engine up. If you want to run it, I would say not to go too much over a 50 shot. Even a 75 shot might be pushing it.
For the cash that you'd spend on a good nitrous set up, you could buy some form of engine management and tune the extra power out of your engine safely. I'm not trying to talk you out of the giggle gas, but it's not really going to be best at this point in your cars mod path.
Just my $.02
Here's a thread with some pretty good info in it though. Nitrous ?
My car is well, it's like 10 lbs of shit in a 5 lb bag...
alright, understandable. what about an intercooler sprayer? like the n-tercooler system? how well would that work? or, what would i need to run a 75 or 100 shot? like what fuel upgrades and how would i get a good tune?
