I love 4doors. It's my love. My car is rusted, and I'm just getting tired of old repairs going nowhere. So I'm thinking at getting the EK EX 4dr (dunno the American equivilant). I'm pretty sure this is the one without the y8 (I think it's the a6 or z6). So I want to go turbo either way... Can I treat the a/z6 as the y8 in terms of ordering parts like cams and valves? I'm 100% I don't want the 2dr y8.
