Hello F20 addicts, since the discussion in the other thread was offtopic, I will quote those posts here regarding the hardware differences between the 116i and 118i. It is known that the exhaust is different and also the oil cooler is missing from the 116i. However if anyone has info about the turbo (and possibly other major parts) being different, either on all cars or just on some, please let us know.

Here, for instance: http://www.realoem.com/bmw/enUS/select. I recall somebody shared (on a local forum) he had done this and the list provided above should be complete. FWIW

However 116i turbo has a different code from the 118i, but same as 114i. Weight is slightly different at ~70g. Any idea about this ? Is it actually a different turbo, or maybe just some different minor parts (orings, manifolds etc.) ?

Edit: I have searched for both codes from BMW, 11627643719 and 11627643717, and they appear on specifications for the same turbo (here, here or here), Garrett Turbo P/N: 819997-5001S GT15, Model MGT1549ZDL. So maybe the same basic part after all ? Does anyone know more ?
