You'll need to be a bit more specific as to your ultimate horsepowr goals. The chasm between 400 WHP and 500 WHP is quite wide.

 

you better get your flame suit ready, but i say a 30r turbo kit and cams, and the basics like TBE, intake, fuel pump and other little things

 

get your basic bolt ons done before you go to a bigger turbo, there is alot of info on this site, read a ton before you go throwing your cash around.

 

You'll need a search. The search is a great mod that only searching will find.
