Does anyone know if the internals on the 120d are the same as the 123d?

Can I ask why you want to know?

Are you looking at changing an entire engine over or just a few components?

No Iím wondering can the 120d be remapped to put out the same 200BHp as the 123d with no long-term effects.

your best bet would be to check and cross reference on RealOEM - I checked the F20 engines and confirmed the 116d and 118d are exactly the same (only difference is the maps they run)

Old post but, the 123d is a twin turbo engine and the 120d is a single turbo engine.  No amount of mapping on a 120d will get it to work like a twin turbo'd engine.  You might be able to tinker with a 120d engine to give you the same bhp as the 123d but it won't be quite the same in terms of power delivery due to the single turbo. 

Be exclusive and drive a Petrol 5 Series!
