gt motor into a gs?
 

first of all, very new to this. second of all i have a 3.0 L V6 engine off of a 2000 eclipse gt 2.4, 4 cylinder. i recently found a guy who has a 2000 eclipse gs. i was wondering if the engine will fit? The guy did not have his VIN # at the time and if so what problems if any will i run into during instillation.
