Question S63B44TŘ (S63Tu engine) weight?

I can't find any info on this whatsoever. Tried googling it and searching here to no avail. I don't think BMW has released any official info regarding the weight of the engine. I can't even find the weight of the N63 or S63. Just wanted to know for comparison's sake since the dry weight of the S85B50 was 529 pounds.

Doesn't Wiesmann purchase the engine for use in their MF5 cars? It is a round about way, but you may could find out from them...

BMW S85 weighs 240 kg. BMW N63 weighs 228 kg. Because of complex turbosystem, S63 may weight a good amount more. BMW will not disclose the weight, because want to put into our mind that turbocharged smaller engines are lighter than naturally aspirated larger engines. This is not true for high performance engines, or only true for very high power outputs, which however are not realibable for road, but only for race purpose.
