Other than an after cooler what else is different? Would it be easier,
cheaper just to replace the engine.

I suspect it's probably going to be cheaper to put your engine up for
sale and buy the one you should have in the first place.

Things that are probably differant, the head on the bigger engines is
probably a four valve per cylinder (if it's not the valves are probably
differant), I suspect your's is only two valves per cylinder. An
intercoller, a larger turbo, larger injectors, a larger injection pump,
probably a bigger supply pump, larger oil cooler, possibly a fuel
cooler, larger cooling system, cam shaft, pistons might be differant,
larger oil and fuel lines, differant engine mounts, ect. It would take
a lot of work, probably void the warrenty, not worth it.
