[QUOTE="astroboy, post: 351997, member: 4527"] The construction material for the engine block has nothing to do with power la. If power-to-weight ratio, then yes. Power is determined by the compression ratio, displacement, ignition timing etc but not the engine block material. The use of magnesium alloy is purely for cutting down weight and upset the manufacturing cost because magnesium more expensive la.. Maintenance cost for the engine block? I can only think of crack welding or block replacement. What other thing to maintain for the block? [/QUOTE]
