This is exactly what i was looking to do to my car. I also have a 2000 honda civic ex and want to swap the motor. Where are you ordering your motor from? do you know if it is a reliable place? I just want to make sure i get my motor from a reputable place. sorry for the questions. Are you switching your car from an auto to manual or was it already manual? I have to switch mine over to manual so it involves a few more parts.
