Hello ! Firstly I want to apologize in advance if I posted this into the wrong section or if this was posted before . I got this crazy idea this days of swapping my regular 1.6 liter engine from my E30 with a diesel engine from e46 . More exactly with M47TUD20 . My question is if that is possible ?! In fact what i actually need to buy beside the engine ? Idk , if you guys got the knowledge on how to do that or what i need to buy , to modify please tell me ! Any advice is good ! Here where i live isn't a common thing to do what i want to do and the forums are kinda dead or nobody is willing to help .. Ty !

I think I've seen a M51 done before, but thats it. I don't know how much help you'll get on here since diesels are very uncommon in North America.My Garage

My brother inlaw had an e39 525tds with the M51 in it, and it was a great car. Would be excellent in an e30, around the same power as a 323i, but much more torque. In the e39, he used to cruise at 80mph and get 43mpg, so the economy should be pretty good in a lightweight e30.
Anyway - here's some guy in the UK who did one:
The M51 from an e34 would be front sump, so bolting it in would be the same as an M50 swap - then you'd need to deal with the wiring and fuel system.
With the M47, you'd have a rear sump, so either fabrication would be needed, or you could try to fit an M42 sump and oil pickup? The timing chain is at the back of the engine I think on those, so probably little chance of the M42 sump working.
Anyway - could be doable, but it's a pretty undocumented swap so you'd be largely on your own.Comment
