Ha ha. Basic mod lists are all over here and MSF as some googling will show. Basically, though, they look something like this:
1) do the 'rears first' = rear engine mount and rear sway bar
2) look after your engine =OCC; maybe EGR delete; HPFP internals
3) flow more =intake (look into 3" as well, but will need a tune to run); racepipe (or a full downpipe if you have money to burn or fingers to bleed); maybe a TMIC (or FMIC if you have spare money and time), but it's not hugely necessary at this point
4) tune =COBB AP or Versatuner. Either OTS tunes of some variety, or a full custom E-tune. Look into E85
5) plenty more, but you should be all over it by the time you get there
Buying parts: direct from suppliers, or through the US suppliers like edge autosport, or gsl rallysport in australia. Read up on any other aussy sellers before you buy and you will learn why.
