All of the engine electronics need to be removed from your car as the Diesel does not use them. Battery in the Diesel is larger due to the glow plugs. Exhaust is different due to the turbo and is larger in diameter as well.


It is probably a big job, Diesel W123s are everywhere so your best bet is to go get a good example and either sell the petrol car or keep it as a second car.
Battery is also larger in the Diesel due to the higher compression ratio.

Thanks,
Mike

For performance, gas FI is superior. But for DIY, especially on a neglected vehicle, I prefer the carbs. They're usually cheaper & easier to get going again.
But in the US, a major issue with the older gassers is gasohol fuel,which tends to eat up fuel system components over time. Also, many of the older gasser Benzes weren't very economical.
So in the past 10 years, I've gone over to the W123 diesel crowd. Simple, reliable, acceptable fuel economy and no gasohol issues.

Happy Motoring, Mark
