Does anyone know what parts (if any) are forged on the U20SED? I'm pretty sure the pistons and rods are not. How about the crankshaft? Also what materials are the other pieces made out of?
Block - cast iron?
Head - ?
Pistons - ?
Rods - ?
Crankshaft - ?
Valves - ?
Any other relevant pieces, please add to the list.
