Non-turbo!!! why?
PUT TURBO ON IT! 
seriously why not turbo-charge it? Anyway, You can try adjusting the valves' http://www.dieselgiant.com/valveadjustment.htm ' also replace fuel filters "1 inline,1 large screw-in oil filter type,1 strainer in tank"

Sorry, none of this applies to this model. All engines beginning with the 60x series in the mid-80s have hydraulic self-adjusting lifters, so forget that. Also, adding a turbo to that engine will not help, it was not designed to accomodate one and the computers have no way of controlling it.

Why is it uncommon to see the usual hot rodding ways for gasoline engines used in diesel engines? I am referring to boring out the cylinders, putting in larger pistons, stroking and porting the engine. What about optimizing the air intake and free flowing headers? Are these useful?

Diesels need more air than they can naturally flow to make power. That means a turbo, supercharger or nitrous.

If its a complaint of less power than it used to have, you might try having the inj's pop tested and re-balanced.
Pump timing and chain stretch doesnt seem to be much of an issue on the 606.9xx engines but I suppose both could be checked on the off chance they are out of spec.
Check to be certain the resonnance flaps are operating freely and clean out any gunk inside the IM and Crossover pipe.
Beyond that step on the go pedal more.

If you have a hundred grand (or two) itching a hole in your pocket you can always design, fabricate and test some yourself. Otherwise, none of that stuff exists.

A supercharger is a relatively inferior concept to a turbocharger since it cannot deliver as much power. Superchargers take power and deliver more (drag on the engine), while turbos have a larger net gain. The problem is that with gasoline egines, especially lower displacement ones, you have lag issues, etc. Diesels have so much air that this is not as much a concern, and it is the optimal situation for a turbo.

Like I said before, it is not a quesiton of diesel versus petrol, MB spends a lot of money to give you free-flowing intake and exhaust from the factory, instead of cheap cars where you have to add these yourself.

Also, having the transmission serviced can increase performance, and you may as well change the differential fluid if it has not been done.

No, the difference is that turbos provide more even boost throughout the rpm range than do superchargers. That is, no gearing required.
In addition, with superchargers, all the energy in the exhaust flow is lost same as naturally aspirated engine. The energy required to drive a supercharger is significant while that used to drive the turbo is almost free.
Now that technology has been developed to allow turbo materials to survive the exhaust heat, the days of supercharging are numbered.
In 2008 the auto industry almost unanimously agrees that the path to improved fuel economy is smaller-displacement engines turbocharged.
Mercedes has officially announced this as its direction.

Superchargers still have their place in applications that require instant boost off the line.

There are zip/zero/nada intake or exhaust restrictions on Mercedes engines that can be "cured" by 'merikun hot rod techniques, always inexpensive. Even for the boat anchor iron these "solutions" are usually designed for, it's more hype than reality. That is, no "cure" required because there is no problem. "Real" solutions are only cheap in fantasyland.
Mercedes are small engines designed to scream on Autobahns. 'merikun iron is humongously big and not really designed to do much past 2500 rpm. Even the later--but definitely not the earlier--Mercedes diesels are designed as Autobahn stormers.

This "iron" technology is mostly irrelevant as regards Mercedes.

I agree that MB diesels are built with high speed autobahn cruising in mind and just as importantly economy.

The BMW engine is still not the most powerful, the 420CDI has 320hp and a mountain of torque.

This is simply the next generation of turbodiesel engines. MB is releasing th next generation very soon, starting with the new 2.2 litre 4 cyl developing 204 hp and 500nm torque (still more hp/liter than the BMW). The MB 6 cyl is coming soon, and will probably outdo the BMW as is the tradition between the two.

The Acura is said to produce about 170 bhp. Good for a 2.2 liter four banger.

In terms of power it is probably the best diesel engine. MB has killed it though.

The Acura engine is not very impressive, that is the same output as the current MB 2.2 4-cyl, which will soon be replaced.
