i have been running a 65 dry shot of ZEX nitrous in my 99 SE-L for almost a year... I've only used it like 8 times, but i'm upgrading to a 75 shot. Until now, the only other mod i've made for the nitrous is colder plugs. With the upgrade to a 75 shot, i'm replacing my fuel pump with an external Holley pump. Is this the only thing i need, or am I forgetting something? And if i were to run a 100 shot, i would have to switch to a wet setup, correct? TIA, i haven't really seen a lot of nissan's with the zex kit, so i'm not sure how it works...

If you have a high flow fuel pump, you won't need to switch to a wet setup; a high flow pump (e.g. Walbro; however, I don't know the specs of the Holley pump you are planning to get) will put out more than enough fuel pressure to handle a 100 dry shot. In fact, I've been spraying a 125 dry shot for several months now with no problems - plugs & A/F ratio on the dyno look good.
