Sounds like you're dealing with a dinosaur. In my opinion, you'd be miles ahead by swaping to a much smaller modern turbodiesel, rather than trying to modify the existing engine.

Consider the fact that you can get a EuroV Cummins ISB 4.5L engine (4 cylinder version of the 6 cyle 6.7L engine that I have in my truck) with the following specs:
Peak torque=760 Nm @ 1400rpm
Peak power=204 hp @ 2300 rpm

Thats more power and toque from an engine with under 40% the displacement. That particular engine is also sold with a single turbo and no EGR. The EuroV engine is sold with an SCR cataylst.
