Little question about n20 set ups?

Ok I was able to pick up a single purge solinoid from one of my friends for like 5 bucks. I was thinking about using it to spray a dry shot in my grand prix gt with it. Just connect a another line to it, and throw on a nozzel and a jet. But now I am hearing from some other people that I shouldn't do that, because with a dry kit I have to have some way to regulate my fuel, and i'll burn out my engine due to it running too lean. But then some other people say my idea would work fine. So I am going to ask you guys, because you've never steared me in the wrong direction! Thanks.

purge solenoids are designed to be open for 5-8 seconds, no more. you should NEVER use a solenoid for something other than its design model. i suppose you could use an n2o or fuel solenoid for purge, but that would be a waste of money.
