Petrol to diesel conversion,help!.

Hello everyone. Am having addiction about diesel cars, somehow i feel very confortable being around with, I can DIY almost everything compared to petrol engines.Now I own one nice W 124,2.3E, I like the look and interior do not wanna part with. I am thinking of a possibility of swapping the engine to 2.0D or 2.5D. Is there much of a difficulty because my worry is of wiring harnesses and electrical issues. I would appreciate all suggestions because the other option is to change the car from a dealer!

Not sure but the first thing is maybe the motor mounts are different...also the glow plug relays, and the guage cluster... would love to have my petrol wagon be gas... here in the states its probably just cheaper to sell the petrol and find a nice 87 diesel wagon... I know in the uk peaple do lpg conversions.

I agree, I like my diesel more...not as fast, but rock solid.

I bet things are pretty in Turku right now huh...Your country is beautiful...in spring and summer.

There is a lot to convert and/or swap ranging from diffs (due to ratio), to fuel tanks/fuel lines, gauge clusters, vacuum lines, ignition switch, throttle cables, wiring, etc, etc.

If you're unhappy with the gasser, sell it for what little you can, and use the money towards a later W124 diesel, like a OM606 twincam E300. When all is said & done, you'll save yourself a bunch of money, frustration, time & hassle.

I've contemplated taking a nice '94/'95 E320 wagon and swapping in an OM603/606, but I'd only do it if you had a complete vehicle from which to scavenge the parts. I wouldn't even attempt to do this piecemeal

Agreed.

I had both the '95 E320 and an '87 300D side-by-side because I planned to do this swap, but after all of the things that I found needed to be changed I decided it wasn't worth it, ... swapped all of the '95 bits into the '87 instead.
