Another thing to keep in mind is that the engine in our Corolla is used in the Lotus Elisse (granted with stronger internals). Monkey Wrench Racing actually has built internals for the 2ZR-FE, so if you were looking at building a motor from the ground up, that would be a route to take, then you wouldn't have to switch out the wiring harness, motor mounts, transmission, and PCM (just need a tune for your build).
