Ecotec head swap onto 2.4L bottom end

I just want to know if this is possibile. MY brother did something similar to this on his Toyota Celica, and it worked great for him. I have a 99 Z24. He wants to take the head off a 2.0L Ecotec and put it on the 2.4 bottom end. He says with the smaller combustion chamber it'll up the compression ratio, and give me the benefits of having the ecotec setup. My question is, is this possible, and which ECU sould I use on this setup if we did do this?

idk sounds kind of sketchy to me and idk how the head would really change the combustion chanmber? the combustion chanmber would be the cyclinder and you not touching those so i really do not know if that would do good/bad for you. Also would the heads off of a newer ecotech even fit on a 99' Z with the 2.4?

i doubt it....the bolt pattern and all that jazz proly doesnt line up. u would proly just be better off getting an actual ecotec engine and swapping it in, because with all the custom parts u are gonna have to make for it to work, you could probably just get a new engine and mod it. the only circumstance that it could work was if the 2.4 and ecotec blocks were modular, but they arent. the only cars i can think of that u can do that on are the older 5.2 and 5.9 dodge's and older ford v8's because the blocks are the same, just milled out to different bores. and i severly anyone did it with a celica. the only other 4 cylinder i can think of toyota making is the 2.5 in the camry, and i KNOW those dont match up.

Okay, I'm not going to give an "I doubt it answer," but rather a "that's not ever going to be possible" answer.

They're two totally different motors.
