From what I can tell the Enclave comes with a 3.6L 6 cylinder engine and you have a 4 cylinder turbo charged engine. If this is correct, I would not try it. I am sure it can be done but this will require new wiring harnesses, control modules, and some custom work to get the engine to fit. Meaning you will need to move engine mounts not to mention change the bell housing (at least) of the transmission to get it to fit. In other words, this would cost far more then just replacing the engine.
Looks like GM is selling direct replacements for about $3,800.00. Then add a few hundred for installation and you will still be cheaper and faster then trying to make the other engine fit in your vehicle.
Sorry for the unfortunate news but I have just seen too many people make this mistake. Unless you are will and able to make all the adjustments needed to make this work, I would not go down that road.
