The 2ZR-FE engine can be built up or modified to produce more power already with the parts available for it and there are more parts that are coming for it too in the not too distant future (performance parts from MWR, tunable ECU's from OV Tuning, etc.). For an engine swap, there is no guide or list as to what engines are verified to fit the 11th gen chassis. However, I can make some educated guesses on what could fit with little to no modification.
The 2.4L 2AZ-FE from the 10th gen XRS may be able to fit since the engine bay size seems similar between the two generations of Corolla's so if you could get the mounts off a XRS, you could modify them to fit if you need to. I'd assume the 2.5L 2AR-FE could fit as well since it is a successor to the 2AZ but you would probably have to modify the engine mounts for the 2AR since the 2AR never came in a Corolla. A 1.8L 1ZZ-FE or 1.8L 2ZZ-FE should be able to fit in the 11th gen engine bay as well but I'm pretty sure the engine mounts would need to be custom made (although, I do remember seeing that some 10th gen Corolla Altis' came with a 1ZZ-FE in other markets so if you could source those engine mounts, you might be able to do something with them). If you want to go fully custom, I saw a 7th gen Corolla with a 3.5L V6 2GR-FE (or was it a 1MZ?) in it and I think the 2GR might be able to fit under the hood of an 11th gen. Now, with that being said, you would need to wire up these engines yourself since there are no plug and play kits for these engines to the 11th gen so that's another struggle itself.
There is also a 11th gen Corolla Altis that is being used for professional racing in Thailand and it has a 2.0L Beams 3S-GTE in it. That, ofcourse, is also fully custom made but it's another option if you are really going to go with an engine swap.
These are the engines that I think could be swapped into an 11th gen chassis and any of these swaps can be possible to do but only if you have the will, the money, the time, and the skill to do them.
