SORRY, I didn't see you were responding to the 4th Gen question! My bad...
For the 3.6L DI, however:
Crankshaft: Forged steel
Connecting rods: Sinter forged steel
Main bearing caps: Sintered steel
also:
- Cast aluminum structural oil pan stiffens the cylinder block structure and reduces noise
− Oil jets cool the pistons, while polymer-coated skirts reduce noise and friction

As I mentioned... my 4.0 was not this robust and it happy with the 100 HP shot...
