I am buying a 1986 Humvee 6.2L NA diesel engine, I have been told they built these engines stronger for the military.

Question

#1 Are the heads are compatable with 6.5L Turbo?

#2 Can I use the mechanical pump on my 1995 6.5L turbo engine?

#3 How big can I bore out the 6.2L diesel?

#4 Can the 6.2L be turbocharged?

#5 Will the injection lines mate up to the DB4 pump if I have to use these with the 6.2L heads?

Once again a big Thank you to any who can help me with my dilemma!
