I have a 96 civic ex auto and i just bought a zex kit from a friend last week for $400 (not a bad deal). I getting it installed sometime next thursday or friday, most likely with the 75 shot on it. From what i've been told changing your spark plugs to ones a degree colder is a good idea. I didn't think about when the car is at wot and the car shifts that the nitrous will be running. While the car is at wot you should know about when the car is going to shift so if u let up on the gas some the nitrous should cut off then after it shifts get back on it. One other thing you're going to need to watch is when the car reaches the rev limiter it cuts off the fuel to the engine but you will be at wot unless you upgrade your ecu to get rid of the rev limiter. I should have everything hooked up for the rescheduled nopi nationals at mir on the 28th. I'll post up what times i get and if anything goes wrong. Btw, i would invest in an air/fuel gauge, fuel pressure gauge and a nitrous pressure gauge. Mine should be in on wednesday. i hope i helped.
