My goal future goal for the car is to get the best mpg and have gained performance as a byproduct of the efficiency gains. I hope this makes sense.
I have a 93 dodge with a cummins, stock injectors, slightly larger turbo (like one step larger) bigger exhaust, and only a little tuning on the pump. Gained me about 30 go and about 3 mpg. That is what I am looking at seeing if I can get something like that.

Look up DieselMeken on youtube you'll see what kind of power these motors are capable of with the right tuning. Advancing the timing and a better exhaust is probably your best bet. An HX35 wouldn't hurt either. The flange would need to be modified. it's a 3 bolt flange not compatible with a lot of other turbos, something would have to be fabricated and welded.
Better fuel economy would be awesome, but the properly tuned 603 gets about 32MPG btw (my best tank, I owned an 87 300D for 2 months).
Good luck with this project keep us updated.
