You can't have either, let alone BOTH more power AND durability.
The 8.2L was CRAP in stock trim and power in terms of reliability. You want to talk about cracked heads, leaking injector tubes, and headgaskets?!?! The WORST engine ever produced for those problems.
The issue with the DD 8.2L was that they did not have ANY material at the top of the cylinders. Yup, none. Just the outside edge of the block and the cylinders, no "deck" on top at all. This causes the cylinder walls to flex and move, and the cylinder heads to flex as well. BAD idea.
The DD 8.2L NA was rated from 130-180 HP, while the DD 8.2L-T was rated from 170-210 (or 230 HP I don't recall any more). That's 8.2L, turbocharged that WOULD NOT LIVE at 210 HP, not even 50,000 miles.
Compare that to the International DTA 360. 210 HP, 750 lb-ft and they lived w/o any troubles to 225,000 and weighed a LOT less.
If you mess with the Gov on one of these, you had BETTER know what you are doing. More than one block has been ventilated due to excessive RPM after someone turned a Gov screw.
I know, we had 16 of them, and I have done headgaskets over 200 times on them. EEeeewwww
