I believe those late 111k motors aren’t massively different from the 202 chassis engines. I can’t remember the compression differences between the supercharged engine and the na but I know rings and engine components are available for that engine. The bearings in a 104 are the same as a 103/603 engine which the 104 AMG crank is from (603). I had 220k on mine when I tore it down and the mains looked great. Rod bearings looked great. The bottom ends are just well made
