hey all. i am fairly new to turbo cars. i am looking to upgrade my stock turbo. i own a 2007 subaru wrx and i am fairly stock. i have a invidia turbo back exhaust with invidia cattless downpipe and a cobb accessport with a stage 2 tune. i am currently looking at buying the blouch 16g xt turbo. my question is what type of supporting parts/mods will i need to do to my motor to be able to use/ handle this turbo?
