Im not sure if its more worthwile to buy a kit or buy the stuff seperately but I can help you out with some mods..
basically the first mods alot of people do are exhaust work and intake to get that thing breathing.. Purchase an air intake, i have the thrasher intake on my 99 gtp. Get rid of the u-bend in your exhaust. Buy a high flow cat. I have a Random Tech 3'' downpipe and highflow cat on my car. What a difference! you will also want to either buy a catback system or have one bent for you. Note: will prob be cheaper to have one bent! After you have those mods done you can start looking into getting a smaller pulley on the supercharger. If you go with a 3.4 pulley you will want to have the pcm reprogrammed, 2 step colder spark plugs (autolite 104's), 180 deg stat. Oh yeah. pfyc.com has a 2 or 3 gauge pod for sale you might wanna pick one of those up with a boost gauge and air fuel gage. If you want to go farther then these mods, im sure the more experienced will chime in. Hope this helps.
