Hey guys. I just picked up a ZEX dry kit w/ NX bottle heater off ebay. So far I am just getting the kit, heater, and a ZEX blow down kit so I can go to the track.
What else do I really need or should really invest in?
I've heard of colder spark plugs, A/F guage...anyone have any thoughts/comments, or better yet experience using nitrous and their set-ups?
By the way, I will be using the 55 shot. Thanks!
