That's a new one. You have a vf43 and WANT a 39? I'm sure you could make that happen very quickly.
OP: The reason they are saying vf39 is because it the most availiable. It was on 04-06 STIs. The 07s have a 43 which has a larger wastegate opening. ie: WAY better for the 2.5l with almost no chance for creep.
