It is amazing to see that the engine layout of the 125i is so close to the 328i (F30) one: BMW engineers have done a kind of copy and paste. Everything is the same even for each small cable !!! The positive side is that the 125i should be very easy to boost to 350Nm /245 hp.
Here is the link for an 328i F30 engine photo:
