Alright - I've got a potential new project on its way. Actually, a pair of projects. I'd like to pose some theorhetical questions at this time. In a couple of weeks, I may be dealing with hard reality.

Let's suppose that I have an '87 190D 2.5 Turbo car with a bad transmission and a pretty rough (rusty) body.

Let's also suppose that I have a very nice condition '93 190E with a bad engine but excellent body, interior, and transmission.

I'm thinking about putting the diesel engine, wiring harness, computer, and everything else that I can think of needed to make the diesel run, into the '93 chassis.

Issue #1 - have any of you guys done this type of swap?

What are all the obstacles I'll have to overcome? I've already contacted the Missouri Department of Revenue - they have a procedure which allows me to do what I want to, so the legal end is covered.

One of my concerns is the ignition switch/vacuum system. I haven't yet figured out how to make the gasser ignition switch work with the diesel engine. I assume that the gasser doesn't have any provision for shutting off the diesel engine via vacuum. I may have to swap part or all of the ignition lock mechanism.

I have considered the fuel tanks and lines. I'm not sure if the gassers use a different fuel line setup than the diesels. That wouldn't be too difficult of a swap.

I'm not sure how much of the wiring harness I'd need to swap. Should I take the fuse box, under-hood harness, and under-dash harness all from the diesel and swap it into the gasser body?

The exhaust is probably different, but should be a fairly easy swap.

Does anybody know if the diesel motor mounts will work in a gasser chassis?

Anybody have any other ideas about issues that I would have to address?

SteveM.

I have done 83 SD motor into 85 SEL body.

Ignition switch, Simply remove gasser ignition switch, and replace with diesel, then change tumbler over. 2 hour job max. ive done it about 3 times, once it took me about 2 hours to do it, once it took me like 20 minutes.
Run vacuum lines into car for shutoff switch,


Gassers have a fuel pump which should be removed, you also have to remove the little plastic flap inside the filler neck or you will not be able to put the diesel nozzel in.

Try to simplify the wireing, get rid of the EGR, i dont have specifics on your car but it is going to take alittle doing to get the glow plugs working correctly.


On the W126 the diesel motor mounts work just fine however one of the brackets that mounts the lower part of the engine shock is on the wrong side, so i didnt mount an engine shock on the driver side.

I never got the tach to work on my SEL after the swap, but i never really tried to hard.

Goodluck.

You will need the differential and driveshaft from the diesel. I do not know if the gasser tranny can handle the torque supplied by a diesel. Also have to watch out for starter placement and other bellhousing issues.

Yes, I think that I'll use the 2.65 rearend and the matching axles from the TD car. The transmission should be plenty strong. I believe that the 2.6 gasoline engine probably puts out more torque and HP than the diesel, but I haven't looked it up recently.

You should also consider whether you will still be required to have your gaiser pass emissions. In the eyes of the law where you live they may not be willing to reclassify the vehicle as a deisel and thus exept from testing.

2.5 turbodiesel:

123hp@4600rpm
168lb-ft@2400rpm

2.6 gas:

158hp@5800rpm
162lb-ft@4600rpm

Should handle the power and torque, but shift points and torque converter might be a little out of line with the power.

The diesel car has better sound-deadening inside and out also, you'll hear more from the engine putting it in the gas body.

What about engine weight? I think the Dt has heavier front springs and shocks also.
