#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!
The heads will fit
The mechanical pump will work
You can turbo the 6.2

The DB4 IS NOT standard IP used on the 6.2/6.5

If you mean the DS4 electronic ???

The lines are not the same... The DS4 uses a different fitting on the IP end than whats used on the DB2

The basic engine is the same from MIL to CIVY
All internal parts are pretty much the same stuff.

The accessories are different to fit the HMMWV application.

Hope this helps
