Re: how safe is the zex kit
Safe is a relative word.. 
As for the wet/dry argument:
That has nothing to do with whether it's safe or whether it's stock. How you introduce it into the engine doesn't matter, it's the amount of nitrous that matters, and whether you have the fuel to safely support whatever you add. Dry is easier with small amounts of nitrous, because the install is easy.
What you should be concentrating on is how much you want to risk your engine. Figure out a safe balance of power and engine stress that you're comfortable with, and shoot for that with the amount of nitrous (or type of prepackaged kit) that you choose. Just like any other power adder, the key is in the tuning..

Re: how safe is the zex kit
horrid response, silence yourself now.im assuming you think that the nitrous is hitting the combustion chamber DRY for some reason. It still has to mix with fuel when it comes through the intake manifold and hits the injectors points, when the air/nitrous/fuel are swirling through the intake manifold to the combustion chamber they are mixing. Its the ratio of nitrous thats gonna not be safe for something, not really the way its put into the engine. There are arguments that dry setups deliver more nitrous to closer cylinders but i havent read anything that really proves it but with arguments on which cylinders run hottest in a car, its a good argument. I bet you think nitrous is what causes the damage to a motor huh ?.

Re: how safe is the zex kit
What you're saying is more than a little misguided. It's not even true in fact.
Smoking with a wet (or any other type) nitrous kit is from improper tuning, in this case too much fuel for the amount of nitrous added. You can do this with a dry system also, if that isn't tuned properly either. This is safer than running lean, and just wastes gas (visible by the smoke).
I have no idea why someone would tell you that a dry system does more damage, the only thing that does damage is adding power if the engine isn't strong enough to handle it or is not tuned correctly so there are lean conditions, detonation, whatever.
This is like saying that a carburetor will hurt your engine, and fuel injection won't hurt your engine but it makes the engine stutter. Well, if they're both tuned like crap, they both perform like garbage. Neither will hurt anything (and both will perform beautifully) if they're tuned to any degree.
The fun thing about nitrous kits is that anyone can drop a few hundred bucks, put on a nitrous kit, blow something up, and then tell all of their friends that nitrous is unsafe and it blows up stuff. These people don't have any common sense, don't believe in tuning, don't think they need tuning, or want more power than they should be adding and are too lazy to so the supporting mods. Oh, and the tuning. Have I said "tuning" enough?
Seriously, one of my biggest complaints about the tuning industry (and not just imports) is that misinformation spreads like crazy without any real understanding of what is actually happening, or why. I had a customer a few years ago (not automotive) that complained about reliability all the time, and told everyone he knew how bad our product was. It turned out that he had our product improperly installed, improperly wired (don't get me started on that), and improperly setup in software. He was a raging idiot and did huge damage to our reputation because of his stupidity and unwillingness to figure out what was wrong, or why.
All I ask of people is that they can support their opinions and don't just spread rumors and third,forth, whatever-hand knowledge that isn't even true.
