The 6.5 pump is going to have more potential for power if you decide later you want to lower compression ratio or whatever and go for more power. The 6.2 pump will be adequate if you turn it up 1/4 - 3/8 of a turn when you put the turbo on, but its not far from maxed out there. It just depends on what you think you'll do later on.

You'll have to be more specific. Are you talking the DB-2 pump vesres the DS-4 pump? The DS-4 is eletronic. And a major piece of crap!! The DB-2 will flow plenty of fuel. Even with the marine injectors.

The DB4 is electronic, and looks totally different than your 6.2 pump. The early 6.5 is a DB-2 pump just like the 6.2 pump does.
