Hi there

i would recommend invest some money to ARB's(Anti Roll Bars something like Whiteline),Droplinks(CDF or Whiteline),Wheel Alignment,i assume you are running front 2 pots,if yes i would recommend have look for Subaru 4pots and get decent pads(EBC BlueStuff NDX or DS2500) with good discs and braided lines too,and you will be much safe and better on tracks than before.

For power depends how much power you are looking,if you are looking for around 330-350bhp you will need at least VF30,VF34,VF35,550 STi pink injectors(not sure if you have 440cc injectors which can be FPR good for your power),STi TMIC(FMIC will be better in longer run and for track days),and plus mappable ECU like ESL,SimTek or Apexi PowerFC.
And i'm not sure if its your engine/clutch/gearbox will hold this power increase.
