yes they are the same engines.
Yes many people swap engines in RC Cars. This can be done. This site teaches you how to replace the engine in your RC Car : http://www.rccaraction.com/
Yes. How easily this swap will be depends on what the engines are.... if you're replacing, say, a 4.3 V6 with a big block engine, there'll be a lot more work to be done than if you were trading engines of equal displacement.

Not easily. The ECU will be different and the motor mount spacing isn't the same. Popular engines to swap are the 1uzfe 7mge and 7mgte
You can only swap an engine of a Civic Hatchback with an engine of a newer car. Its only legal to swap in engines of the same or newer OBD series. So the Civic engine you swap with has to be a 94 or newer but any of those engines will fit.
If its the 2.5, you can swap it for some of the older eclipses and Chrysler sebrings. They use the same engine. (Mitsubishi)
NO, not easily.
