(04-19-2017, 10:04 PM)R-3350 the only time i have seen the pistons with the recesses is in NA engines and generally only the after-market replacements.
This is a core engine I got from a neighbor. and it was a turbo motor. I have another engine out of a car that only had 105,000 miles on it and it has the recessed pistons also.

This was a core motor I got from my neighbor. When I tore it down it had #1 rod bearing out. The piston was beat up and #2 piston had some scoring from trash in the oil. I have three engines torn down and two of them have the recess skirts and one has the solid skirt.
