What do you guys think about doing the OM617 swap? 5 cyl. 125Hp 181Tq with turbo
Should see 28 to 35 MPG and from what I understand these engines are as rock solid as can be.

I'm not sure all that will have to be done to do the swap but I bet it would be fun and not to crazy challenging......I hope:D

The conversion has been done a few times into Toyota and from what I understand it's not the hard to do.
I just bought a 1982 Benz 300 Turbo Diesel car with 162K on the clock, the car runs great!!
 
here is my new Benz:party:

Ive seen alot of write ups on ppl doing the benz swap into Jeep YJs and TJs but not Yotas... I do know that those things run for ever though, good luck.
 
I am still on the fence....I want the added power and the better fuel mileage but I also don’t want to take away from the value and originality of my rig.
If I do the swap it will be the engine only I will keep everything else Toyota in my 4Runner. I will be sure to do the conversion justice by making it look bone stock, like the truck came with a Mercedes diesel engine from the factory. I may have to use the Benz power steering pump and A/C compressor not sure if I will need anything else. I may also improve the turbo efficiency by adding an intercooler.

Hey guys here is the engine shots:)

I think I'm going to fix up the Benz as a driver then tag it for a month or two. I want to drive the car with diesel power to see how I like the performance and drivability. I should get a good idea of the fuel economy as well since the car weight and 4Runner weight is near the same.

any thought to what transmission your going to use to adapt a merc motor to you toyota driveline?
that would be the big what if for me
 
I'm going to keep the 5speed trans that is in the truck and use an adaptor plate to mate the Benz engine.
The exhaust is also not that hard to run even though it is not on the same side as the 22re.
 
Yeah, those are usually really pricey. I saw a guy on youtube making a trans adapter plate out of 1/2" to 3/4" aluminum for an electric motor (electric car) with a cardboard template and a jigsaw!
 
We are a machine shop so the plate and pilot bushing is a none issue. The coolant system maybe a bit hard because of the added langth of the Benz engine.

I had a friend up here in Toronto do the conversion into his '89 4Runner. Here is link to his build.
Turbo Diesel 4Runner

I did see that build and some video on the running 4Runner:trophy:
Would you please give him my info or PM me with his contact info? I would like to talk with him about the build. I know he has a body lift and I’m not sure if the engine will clear the hood without a body lift. My 4Runner is my daily street driver and I don’t want to lift the truck. I also want to keep my A/C I want the rig to function as it would if it was a factory option right from Toyota.
 
This is awesome. I will be following this thread for sure. If my 3.0 goes I will be looking at htis as an option.
 
I will see if I can find his info, I haven't talked with him in a year or s but he did open a shop up here. I will have to get back to you. He was talking about selling the adapters at one point.
