I can get a 75 shot Zex dry kit for dirt dirt cheap. What else would I have to upgrade besides spark plugs to very occasionally spray a 75 shot? Thanks guys

 

Sounds good,I would suggest a Window switch at the bare minimum. A bottle heater,purge and fuel pressure safety switch would help the system work to its full potential safely.

well, im buying the kit used from a guy that i know. It is in real good shape and he is practically giving it away so I just want to know what else i would need if i go with this kit. It does have the purge valve and stuff like that. Also it is a type of kit you hoof up to your tps and it sprays when at WOT. Do I still need a window switch? I dont know anything about nitrous at all. I am assuming that the window switch lets it only spray from X rpm to X rpm, correct? Thanks for the info so far though. Im slowly learning.

 

I would still get a window switch. You are correct, the window switch will only let you spray from X RPM to X RPM.
