Your motor is a DL-42 Nath.
If you run low boost your motor will handle it fine
It looks as though your oil filter may get in the road of the turbo setup.
If you look at the Rocky manual you downloaded under "Engine Mechanical", on page EM-6 and EM-7 they have outline views of yours and my motor.
You can see that your oil filter is upright, where mine is slanted to clear the turbo.
The fuel pumps look identical except for the boost compensator
Other than this, they look basically the same Nath.. just need to sort out the insurance/engineering viewpoints and you'll be sweet
I beleive you can get better fuel economy, as the motor does not have to work as hard. But, once you get the feel for a turbo you tend to drive a little harder than you normally would

Mmmm Boost
I accelerate in the Rocky a lot harder than I should... full boost through to at least 2500rpm in all gears until I reach the speed limit... I know this throws economy out the window, but I dont like being a slow 4x4 driver.. lol... in saying this, i have never dropped below around 450kms to a tank even driving it quite uneconomically.
I'm still used to driving my other car... lol
Although, I am currently testing my mileage driving like a diesel should

I'll get back to you on that one
