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?

 

With dry and wet shots you put a nozzle into your intake pipe about 6 inches from the throttle body. With a dry shot it just sprays nitrous but with a wet shot it sprays both nitrous and extra fuel. Now with direct port you put a nozzle in each of the 4 intake runners. It's more efficent because it sprays pretty much directly into the combustion chamber. Now I don't know much about using nitrous with turbos but if your set on doing I would either use the N-ter cooler kit from nitrous express that sprays nitrous onto your intercooler to lower the intake temps or maybe a 35 shot or so just to help a bigger turbo spool faster.
