I saw there was no response yet so I thought I would give it a crack...I've seen around this board that as long as you don't boost your engine above 5-10psi you should be ok, depending on how well your engine is running with 160+k miles on it...I am looking into getting the entry level paxton or vortech...they both make around that psi I was talking about...Most likely when you instal your supercharger you will have to back the timing off a bit, or use a higher octane, or both maybe to keep it from detonating...Detonation is what will make your engine really suffer under boost...You can buy either of these supercharger kits (They are complete) for under 2000.00...Anyway that is my .02...other people on this board are much more knowledgable then me i'm sure so keep asking as advice I have received here is never wrong...Usually ghostdog helps me with tech, and noslow5.0 helps with supercharging questions...they seem like they know what they are talking about :eyepoppin
Good luck and please anyone correct me if I mis-stated something...
