how are you all, I know this sounds crazy but I want to put a 3l 5 cylinder diesel into a w124 replacing the original 230 petrol 4 cylinder, I am wondering if it would bolt up to the w124 gearbox.

years ago i have put a 200d engine into a w114 petrol 6 cylinder and it bolted straight up all I had to worry about was the start/stop setup.

can anyone give me some ideas?

You'll need the trans too. It's been done.

ok thanz for your reply johnhef , I have no problem doing that if anything the more simple the better, is there any problems that you could think of? would there be much mods needed for the 124 to accept gearbox/ driveshaft ect???

The one I had seen was on ebay- Dunno what they did about the driveshaft, as for the engine, it's not going to take much for it to run in that car, linkages may be a little troublesome but I dont see much problem with it.

yep thanx john, I will have a measure up, I thought on the off chance someone might know the short cuts, but yes you are correct they are not as hard as some other conversions would be, Im gunna do it

You'll just have to look at the driveshaft. If it won't bolt up you may have to have a front driveshaft made up with the 123 front and the 124 rear. Same for the shift linkages. Threre are some little differences such as the oil pressure guage is mechanical on the 123 and electric on the 124. Other things as well, I am sure.

Good luck.

IF you pull the engine from a w126, it also has the electrical oil pressure hook up.
