2L NA is not available for RHD regions Civics . And Elantra other engine below 2L is 1.6 so they have no other option.
Keep in mind, we are CKD, we are not R&D and when the steering orientation changes, many items orientation also changes in the engine bay. I don't expect a 2L in RHD Civic. You might see an improved 1.5T and 1.8L NA.
