Which of those two is safer for a lightly modified 03GT and why (In terms of detonation, installation, reliability)? What brand should I pick? I know the wet shot will give more power, but i dont wanna change out my fuel pump or anything like that.

 

wet.. is safer and it depends on how many HP shot are you planin to run?

 

go with a 75 dry shot,breeze to install and you probaly won't have to mess with ignition timing either

 

Yeah thats what I figured...Now to choose between NOS and NX...

 

i was about to order a zex wet kit(82023), would i have to advance the timing?

 

You don't advance the timing on laughing gas, ever.

 

you want a wet kit with an '03, returnless fuel system.

 

Exacltly. Always retard when adding the juice.
