I have been shopping around at different nitrous kit I want. I have a stock bottom end right now so Im only going with a 100 shot but I want a kit that's going to be upgradeable when I do want to step it up.Ive been looking at the NX twin plate system which is upgradeable to a dual stage and it goes in 50hp increments up to 300hp but if I ever want to get a progressive controller I dont know if I can get what I want out of it and it doesnt seen like NX has nearly as many accessories as NOS does and I dont know if parts are interchangeable. Any suggestions or info would be appreciated.
