Due this information and smaller bore, original is 84.5mm and my is 81mm JE create the piston with compression 9.3:1 with same style of dome because of direct injectors and velocity
Edit : I had optional with flat style piston but choose it Dome
I know i cannot sleeve an engine with a 20v DeWalt in my garage. I was curious to how and where you were getting the parts as I could not find any aftermarket support for this engine (internal wise). The amount of work that's going into the engine for the time,labour and parts I think there is better options. Just the cost in new timing chains and tensioners, pistons, gaskets, o rings, hardware and main and rod bearings is the price of a used engine, for my purpose is not worth it.
I've been noticing with these engines they seem to be failing when people start throwing big numbers at them. Usually due to lack of lubrication. If your running a turbo set up now, probably a good chance you could be starving your bottom end as well due to the extra oil usage in the turbo as the supercharger is internally lubricated by a sealed system. Might be worth modifying a oil pan to hold some extra oil.
Did you have any wear on your bearings or build up in your pan?
Good luck with the build, be interesting the see for sure.
