Anyone out there know if an engine from '80 300D will work in a '85 300D and whether there would be any loss of power and gas mileage? I have a 85 300D with a spun bearring (sic) and have access to the early engine for free, but am far from sure as to the compatibility. Both are diesel turbo engines. Thanks

No it wont work, send the free engine to me. just kidding it will fit. Please confirm though.

the 1980 is a non-turbo.....you will have noticibly less power..however you can use it in your 1985....remember most Euro modles were non-turbos.

I thought it wasnt turbo either but he posted that they were both turbo. Maybe it is not the original motor

Correction - the 80 engine that would be installed in the 85 300D is actually 300SD - How would this change/increase/decrease labor costs? and compatibility issues? Thanks

frankenstein ac bracket, different ac compressor and lines. maybe other things.

There's a duplicate thread in the Tech Help forum.

Engine mount pedistals are different, but they bolt to the block so no big issue..swap over your accessories onto the 300SD engine...and the mount pedistals and you should be fine..
