Need advice on a nitrous system. I posted in the PA forums but got little response. I want to get a basic dry kit. I'd like to go with dry just in case the car has to go back to the dealer for service (ease of removale) I'd also like to keep the cost of the kit relatively low. I also want it very safe. I'm goin to keep it under a 100 shot. I know I need the safety features like window switch and wot switch. What I'd like to know is the specific kit I should go with and where it cheap. And also any other features I should be looking for.
