For larger displacement u need om603 3.5 crank and custom pistons, in just boring there is no point, m103 doesent have enaugh cilinder wall.
And like mentioned before, 2.6 has smaller valves.

I appreciate the advice. Do you have any idea if the 2.6 crank or 3.0 crank is stronger? I would guess they're almost the same.
As far as boring goes, the m103 has plenty of cylinder wall. AMG and Brabus bored the 3.0 to 3.6. I wouldn't bore it that far (especially if going turbo) but if AMG did it I'm sure its safe and I'm sure 3.2 would be fine for a turbo application.
