Bmw n47 engine

[Beamishken]

Hi I'm currently repairing a 2008 520d we bought for my wife with a snapped timing chain I've priced all the bits up and it's around 1000- £1100 in parts to rebuild the existing engine so I'm considering buying a complete salvage car to get the engine from
Does anyone know if engines from other models are compatible ie is the 118D & 320D the same basic engine? I'd be using all the 520 outer bits ie manifold pump turbo etc
Thanks in advance
Ken

If you use realoem you can look up all the part numbers and see if they are the same.

Hi yes thanks I could look up the part numbers but there are 100' of parts that could potentially be different across many different models. it'd be nice to find someone with intimate knowledge who could confirm what's the same and what's different
Thanks

Yes, the base engine will interchange but unless you've heard it running, chances are the chain and guides will be tired. Back to Square One!

I would personally rebuild yours, but bear in mind it may need a crank as well because early ones had the chain sprocket machined incorrectly.

What you could do is buy a Cat C slaughtered car, break it and sell the bits you don't need. Copra is about the best bet.
