I had the Zex kit with a 75 shot in my H23 for 3 years with NO problems.If you convert it to wet then I'd be a little more worried about yur mods and build-up so far.I believe that NXpress makes a conversion but I don't know the cost.Zex has just come out with their own wet system so maybe you convert using that.The Zex is total "plug n play",you'll have no worries because it's self regulating.I would definetely invest in a bottle mounted nitrous pressure gauge,a bottle heater and a purge kit to make your nitrous experience as enjoyable as possible(plus the nitrous gauge on the bottle prevents you from getting ripped off at refill time).If you convert to wet you might want to add injectors,some sort of fuel controller and an air/fuel ratio gauge to start.Hope this helps,you'll be fine with the Zex and make sure you research nitrous as well so you become a responsible user.:thumbup:
