95 E300 Diesel- Add a Turbo?

My wife wants some more oomph in the 1500-3500 RPM range.
What all would be entailed and needed?
Thanks in advance.

A turbo would only help above ~2700 rpm.

Diesels are slow off the line (hell, they are slow all thru the RPM range).

A turbo and non-turbo motor are different internally. A turbo motor has beefed up connecting rods and such to accomodate the higher stresses a turbo adds.

If you add a turbo, expect to shorten your engine life dramatically.

Have her drive a 190D 2.2 or a 240D with the AC on and then have her say your car is slow! Then she will respect the acceleration that car DOES have! My car is slow as balls.

You can't just "add" a turbo. The turbo version of the 606 motor had an intercooler as well. I beleive it was water-to-air. You'll need new exhaust manifold and I'm sure that many of the internals are different. I beleive the injection pump is different as well.

Maybe it would be more cost effective to trade in for a 1998 or 1999 E300 Turbo.

cpermd, you can't just "add" a turbo. Don't even think about it. If you must have more power and want a diesel engine, sell your car and upgrade to a 1998-99 E300 turbodiesel (~175hp, 0-60 in 8 seconds.)

Also, "turbodiesel" had some slightly misleading information. Not all diesels are slow as hell off the line! The underpowered ones are - like the 240D, and 190D 2.2, especially the auto tranny versions. However most others are NOT slow unless there is something WRONG with them! Most should be pretty quick off the line, especially if the IP is properly calibrated, which does get more rare as the cars get older. To check your car, clock it 0-60 and see what the time is, compared to MB's published specs. My cars do it in about 10-11 seconds, which is dead on with MB's numbers (10.9, 0-62); and your 1995 E300 should be roughly 13 seconds (you have about 15 HP less than I do.) 1985 and older turbos should be ~13 seconds (E-class) and 13-15 seconds (S-class). "Turbodiesels" SDL should be 13-15 seconds. If your numbers are too high, you have a problem and should fix the car.

Oh, and a turbo will last just as long as a non-turbo engine. What "turbodiesel" meant was that adding a turbocharger to a normally-aspirated engine will drastically shorten engine life - this is definitely true for the older OM617 engines, and I presume it would apply to your newer OM606 as well. The OM617's had totally different pistons, etc in the turbo versions. But the models that came from the factory with a turbo will last forever too!


HTH,
