Your 4th gear is 1:1 in the automatic (minus TC losses), should give you a starting point.

I don't believe MB ever sold a turbo diesel with a manual trans.

Of course they did. I almost bought a W124 and there is a W123 wagon at the musuem with a 5 speed in it.

They never sold a manual OM603 Turbo in a w124(I dunno about a w126, doubt it). That's where all the drama lies.

I have only heard of 2 others that have been sawpped and talked about. I will admit I do not run in too many MB circles so there could be more. But I believe most of the swaps are 2.5's(w201, w124) followed by w124 gassers.

PS...

I simply have to get my chicken coop finished today!! No transmission stuff till it's done. Smelly chickens in the basement is lame.

Incorrect. There was a Turbo 250D in Miami that I was thiiiis close to buying. VIN decoder and owner said it was a factory turbo with 5 speed manual and sport handling package. Dealer was Guadalupe. Given the dealer it was probably a very custom job, but from the assembly floor none the less.

Getting closer..

Okay, but isn't the 250D a 5-cyl 2.5 turbodiesel / OM602?

Does anyone know if a w124 clutch pressure plate will fit a w201 flywheel? I can't seem to figure it out:confused:. The w124 has a slightly larger clutch than the w201 2.3 and I would like to use it if it will bolt up.

EDIT:

Someone confirm what I am reading here.

Same except for timing marks which I do not need. So if I read it correctly... I can use a w124 clutch, which is like 9.5"

5 spd transmission is in. I am waiting on a custom driveshaft to be made. Seems the '87 300d has a larger rear diff yoke than all the other's, same size as the w126's. So I have "small" yoke on new transmission and all "big" stuff past the carrier bearing. Could not come up with a bolt on solution so my only choice was a custom front driveshaft. Which is not cheap btw :(

Why not just swap the tail on the trans?

But that wouldn't help anyway. The spline at the carrier bearing is larger on my car vs. a 190

The only alternatives I could find was to swap rear diff yokes and use a complete 190 driveshaft, If the length was right.

Or see of I could swap carrier bearing splines at the carrier U-joint.

Keep in mind all this w201 stuff is smaller than what is in my driveline. I don't really like the idea of changing it all out to smaller stuff. I would have swapped trans output yokes so I could stay with larger stuff.... just got to be too much of a PITA. Laying on the floor for hours under a car is hell on my back.

I do need to get rid of this other 5 spd stuff.... I still may package it all up as a swap kit

Is it in the USA? Didn't think so.

The W124 was in Miami, the wagon is not. They still made them.

The W124 was a conversion or Canadian import then.
