[316if30]

hello guys,
i have 2013 316i with N13 engine for 7 years and after 140 000 km of driving, i want to swap my engine to a new or low millage one because i repair it several times before and now i decide to change the engine but i want to swap it with an N20 engine from a 2014 328i because it's more accessible in my country. now i want to know which parts i have to change because i think its not necessery to change anything else apart engine and turbo system. my car have 8 speed Automatic ZF (8HP450) gearbox which i think is the same on that 2014 328i, so what do you think?
anywhere, i have to change the engine and i think its a better deal for me to go on N20. should i change the ECU or Intake System or anything else?
