1) What is the difference between NOS (I'll just say NOS because it's quicker than typing "nitrous") wet and dry shots?

A dry setup is just straight nitrous. It's up to your fuel system to supply the extra fuel. A wet system injects extra fuel along with the nitrous via a backup pump that's engaged when the nitrous is switched on. These systems *can* be dangerous since it's possible for the extra fuel to puddle in the intake and cause a backfire that'll blow the shit out of your intake and make your throttle body blade look like a taco shell (trust me...I've seen it happen). Nitrous alone won't make power...it'll blow up your motor. It simply allows you to burn more fuel thus making more power.

2) What does a "60 shot" mean? What kind of measurement is that?
|
Basically that's the measurement of the hp added by the nitrous injection. It's hard to predict how much nitrous you're injecting without a dyno. A 75hp jet won't always give you 75hp.

3) Big question: What is the difference between Direct Port and a Fogger system? To my understanding, direct port is a push-button setup, like in Fast & Furious? And a fogger is a system that just mixes NOS with your fuel at a regular, steady rate?

To my knowledge they're one in the same. On a fogger kit you've got 2 nozzles that are tapped straight into the intake runners where they meet the head (and on some hardcore setups straight into the head). When engaged the jets inject both fuel and nitrous into the intake right at the port (hence the term direct port injection) for better atomization which results in a more even and predictable combustion.
For what it's worth, I wouldn't use nitrous if you paid me. The wear that comes from such a dramatic hit so quickly can really hurt your engine in the long run. Even in a well built motor a good sized shot will eventually take it's toll on rings and pistons. I don't know if Honda runs forged or hyperutectic pistons in stock motors, but in some instances the frequency nitrous combustion creates has been known to shatter hyperutectic pistons. I remember a few years back I was at a car show in KC and some guy had a cherry old Vette ('68 I believe) that he was showing and the car had a nitrous kit hooked up to an rpm window switch (uses your tach signal to engage nitrous automatically at a set rpm). When he was leaving the building he went over a speed bump and the throttle linkage hooked on the bump which pulled the carb wide open. Once the engine hit the right rpm, the nitrous kicked in and he went straight into a brick wall. Killed his daughter and a neighbor girl who were in the car. He's still alive but has some brain damage. I've also seen a 250 shot blow a head clean off of the block. That shit's just too dangerous.
