So much misinformation going around lol.
Engines are 100% identical in function between 2008 and 2021, only differences are different mount brackets in 2014+ for the updated headers, new gallery gaskets, different O2 sensors through the years and some valve changes. Any engine from an 08 G37 to 2021 370Z or Q70 will bolt right up, the same ECU will work but you'll most likely need your original harness on the engine.
