you could just go to summit racing and and pick up a fogger kit and attach it into your air intake just above the tb. unless you want to go out and get a direct port injection system and spend a lot of extra money on other parts....
it seems like a fogger would be best. just remember that b4 you go out and get this, you will have to find a shop to fill your bottle everytime you want to gas it. and you are probably going to need new internals for your engine after a couple of runs on the no2.
