Hey Guys,
I have a chance to offer on somebody I know who has a
1982 Black 240D manual transmission that has turbocharger.
Such a modification will reduce engine life if the fuel was turned up to match
the extra air going in. If the fuel wasn't turned up, then the turbo is useless,
but won't do any real harm either. Since the engine has a life expectancy of
hundreds of thousands of miles in normal tune, it's your decision as to whether
the extra power offsets the shorter lifespan. If you like the car, and the
engine is still in good shape, and you're afraid of the turbo, you could always
tune the injection pump down to 70hp and it should be as reliable as any other
240D.
If you do buy this car, I strongly recommend that you install an exhaust
temperature gauge, preferably between the engine and the turbo. You don't want
to see more than 1200 degrees F on that gauge on an ongoing basis, and any time
above 1300 degrees should be very brief.

All of the above advice is pointless if somebody has gone to the expense and
bother of removing the 4 cylinder OM616 and replaced it with a proper five
cylinder OM617 turbo engine.
