There is no mention of Turbo in repair menu of BMW M2 Competition. But - it's still breakable. So after you break it - you can't fix it. There is just no option to do that in repair menu. So you're stuck with a slow car with no turbo pressure. FOREVER.
@2Technical thanks a lot for those setups, you don't even know how helpful they are! Just got promoted to Masters in my Peugeot 208, your setups make aggressive and fast rallying such more controllable and give a chance to recover from mistakes instead of having to face frustration from a full-scale crash. Your work is deeply appreciated, sir.
