Looks like the road to more power from x40 is going to be easier with closed deck blocks and balancer shafts:
New B58 (This pic is of an S55 but shares the design)
N54:
I think the in-cylinder temps will be much cooler with the N54 due to the open deck. Thus less chances of knock when using high boost.
I don't know of any block failures on the N54 yet, but I might be wrong.
It's a matter of time before guys start getting crazy power out of the B58 unit.
