That last post was just the part number for the normal (non marine) diesel motor service assembly. The marine assembly p/n is 1821361c91 and the cam p/n is 1821321c1. They are the same numbers between turbo and non turbo engines.
I sent a quick message to a friend who works for International Diesel. At the moment he can't look up the parts to be sure the cam is the same between the turbo and non turbo motors, but he believes they should be. I can get a more solid answer tomorrow.
