X15 CPL Change

[Truckdriven]

I have a 2020 Kenworth T680 ESN 80143535 that I am doing an overhaul due to dropped liner, this is a 4342 CPL efficiency series high compression series engine and since we would like to program it to 565/1850 I'm wondering if we should rebuild it as a 4343 CPL? I found a same year and model truck with ESN 80167047 for a comparison, looks to me like everything is the same between the two except pistons, head and turbo. Is there anything else I'm missing I should know about? Also what are the turbo differences and can I use this same turbo until it wears out?
