W123 Wagon w/ BMW M30b35 Drift Car
I had a BMW with M30, which I replaced with OM606. The measures between the engines are very close to each other, and I know a few W123/OM606 cars, so yes, it's doable with reasonable mods.
But why use M30? With n/a M30 you'd get about 250hp with reasonable costs, which I think is quite underpowered for that car. The engine is also quite heavy compared to alternatives like BMW M50 or Mercedes M104. Both have proven to be good for turbocharged ~1000hp. For about the same amount of work and dollars spent, why not to do it properly in the first place?
Electrics need attention, no matter what engine you'll swap. There are no bolt-on solutions, but the easiest way is to use engine's own harness married to the car's harness.
