Fa24 opened up?

Anyone know of any shops that have opened up the FA24? I would like to see cylinder wall thickness, rod thickness, crank and pistons.
Reason is, the Ascent FA24 has handled over 500whp on stock internals. I know the boosted FA24 still uses the J shaped rods and the twins FA24 is back to a straight rod.
I don't foresee the internals of the FA24 in the twins to be as beefy as the Ascent, due to the N/A nature of the motor. More interested in cylinder wall thickness, and if a set of drop in pistons and rods is all that's needed to handle 500whp with some boost.

Plus you can see the much higher compression on the NA 24 vs the boosted one. https://en.wikipedia.org/wiki/Subaru_FA_engine
I'm guessing there will be a need for lower compression pistons in order to go high boost.

Well yea duh, its obvious the pistons are higher compression because its a N/A motor.
Im just more curious to see how thick the cylinder walls are and if the wall thickness is comparable to the turbo FA24 in the Ascent.
