It's been known for a long time that the material Subaru has been using to make the blocks, has gotten worse over the years. Less dense. Your standard open deck block is the weakest, no matter how much money you pour into cranks, pistons, bearings etc. I've seen insanely built O-ringed engines warp cylinder walls quite quickly in a race setting with high boost and aggressive anti-lag (European style RallyCross)
^^^ = This.

I'm hoping like god that they are not planning crazy boost, or ultra high compression (less of an issue), or this beautifully built engine will be for nothing.
