Probably a 3.46 like the autos unless MB changed the diff with the manual 300s.

I'd like to try a euro M-pump, crank it up as far as it can go and see if it will make as much or more power than the turbo MW-pump.

Sticks were 346 too.

I remember back when smokey had the hot air engine idea.

When I read his account of it it sounded really great.

He built a car with that idea and offered it to one of the car magazines to test....I think maybe it was a Chrysler k car or one of their earlier little front drivers ....the magazine found it to ping like crazy and not really do that well on economy IIRC.

I really loved Smokey but this was not one of his more successful ideas I don't think.

well right now im looking for a good 617 engine at the junkyard. What should i look for in the turbo? no shaft play laterally?

1981 240d (engine donor 1983 240d) recently rebuilt engine hurray! - No more.. fought a tree and the tree won.

pearl black 1983 240d 4speed (Converted!@$$%) atleast the tranny was rebuilt.

Hi all,
Turbo 240 asked for some pics and explainations of my setup, so here they are!

I used an exhaust manifold off of a 617 with an adapter plate that blocks off the port for the Fifth cylinder. This is quite easily accomplished. I'm a machinist, so I used a milling machine to make the port openings, but It could be easily done with a die grinder and some patience.

The intake manifold is from a 77 240D with the vacuum controlled Injection Pump. The throttle blades have been removed, but the shafts are still in place to plug the shaft bores. I would have tapped them for plugs, but I didn't want to mess up this manifold just in case I want to use the throttle blades for some reason in the future.

The turbo is off of a 2.2 liter Peugot diesel, so it has the smaller .36 A/R turbine and housing. This works much better than the turbo from the 617 because it spools up much faster.

The plumbing from the turbo to the intake is just stuff I picked up wandering around the junkyard, and I have no clue what I pulled it off of.

The exhaust system was pulled off of a 300 in its entirety, so the flex pipe ect, all lines up just like its on a 300.

Here are the Pics. Enjoy!

Cerven,
A good turbo will have no perceptable play Axially, but will show some Radial play. You should not be able to push it far enough radially to touch the compressor housing, and there should be no evidence of the compressor wheel having touched the housing while spinning. If it has, the compressor wheel will have to be re-balanced, and the turbo will at least need bearings.

Radial play should not exceed about a sixteenth of an inch. The shaft should turn smoothly without any "tight spots". I hope that helps!
Cheers, Chris
