yea supercharger is basically completely bolt on, which is nice. auto's do not need a new clutch, as said before, make sure you get the right downpipe with the right amount of o2 bungs. if you don't already have it, get a new catback too.
im gettin a tsudo N-1 catback next month and maybe bad-mab headers with zzp dp..not sure yet..how does the supercharger pulley hook up? with a serpentine belt to the other pulleys..sorry not much of an engine guy..more exterior.
i've got the same set up you're looking at. my set up is: bad-mab header, zzp 2.5" catted downpipe WITH extra o2 bung (with o2 bung plug), and tsudo n1 catback. you will need to get a different pulley. what pulley size are you going to be running with the supercharger?
