Possible.. Probably.. Worth the work.. Probably not.

I mostly have experience going from 1G DSM 1.8L motors to 2.0 and 2.0T. The details for a swap like that are simply the wiring harness and engine. You'd have to make sure the engine harness can be pinned to work with the chassis harness. You'd have to study the wiring diagrams of the Elantra to do this.

Maybe someone else has more info...
