Hey mate, welcome to Perth-WRX.
Personally, I would go down the All Star / Verso route, but thats just me. Being up there in carnarvon, is there someone reputable that knows subi's to carry out the services and stuff? I would be hesitant to get any major mod's done and tuning as if something does go wrong, having a tuner /dyno to suss any problem might be a bit of a mission up there, and trucking the car down to Malaga would cost u an arm and a leg.
Good luck which ever way you go, and enjoy ur orange pig
