Heres proof right here. BMW's own I6 production manager, the head guy in BMW's I6 powerplants saying exactly what I said about the weaker Mg/Al N52 block. And I quote Mr. Welter,"

In the case of the magnesium-aluminum block, Welter says, “Right now, the crankcase-stress of the turbocharged engine is above the limit of the aluminum/magnesium crankcase.”
