New to the whole subaru scene so go easy. Got a 1999 wrx wagon non sti. Just brought a VF30 for it. What is it that I will need to upgrade and look out for when putting this turbo in. The car has 440cc injectors, full system, v7 sti fuel pump, apexi pod etc etc. Also what oil should I be running? What type of performance increase am I looking at? Finally what are the pros and cons of doing this turbo upgrade??
