Sorry for that stupid question about turbo cooling. I guess I'm just old school and knew of the oil cooling on big CAT engines (had one blow one time), but wasn't up on the latest engine techs. I googled water cooled turbos and saw lots on entries.

No Idea what other manufacturers do. This is just what my Cummins mechanic, who has rebuilt / repaired hundreds of B engines told me.

Correct. There might be differences in the heads (valves) and elsewhere.

Yes the fresh water cooling system continuously flows from the block, through the water jacketed turbo, then into the exhaust manifold (not exhaust elbow which is raw water cooled) and then into the fresh water pump which is part of the block.

I can imagine not needing a more domed piston in the turbo version as you would not need the extra compression.

----------------------------------
Perkins 6-354's were the same way. The n/a engines had different heads, pistons, and crank. They even reversed exhaust manifold bolt pattern on the heads so you couldn't bolt a turbo manifold to an N/A head. Cranks were same design, but turbo cranks went through an extended metal hardening process to strengthen them further.
