@JF@Big_Boost_Turbo has pulled the stock B58 rods and pistons so they can put in some forged replacements:

Apparently they are doing 'light weight pistons with stock compression' and ARP studs.

Looks similar to every piston and rod bmw has put in their inline 6 for the past 20 years lol. They are already forged by the way. With pistons and rods upgraded though I'd expect to see these B58 blocks handle 1000whp+ builds. Closed deck and the forged crank is a solid piece again instead of that friction disk nonsense. The two major things that needed addressing on the the N5x/S55 to make big power...

How much power can a B58 make on stock internals?

Even with upgraded turbos and everything else but keeping the stock longblock.
