What is the best N2O setup?

OK I know there are dry shots, wet shots, and direct port. I know direct port hooks up to the block some how. My question is what is the diff between dry and wet shots? Why is direct port more eff? I am doing a rebuild on a motor and building it for turbo. I want Nitrous for that extra kick when I need it. Which setup would you suggest?

Dry shot - nitrous only
Wet shot - nitrous & fuel mixed

Wet is better to use, but more complicated. Dry is good for a low HP shot every once in a while.
Learn as much about N20 as you can before installing/using. I suggest reading some nitrous books. $20 on a book may save your $1000+ engine. It's more the user than the system.

So how do I buy the wet nitrous. Do I have to mix it or will places offer both?

A wet system taps into the fuel line to add fuel into the mix to prevent running lean. There's no difference between the nitrous in a wet system or a dry system, you get the same bottle for either one.

Like Marc-OS posted, it's same nitrous. Different ways of injecting. this is why I posted :
