I have a 2001 Sebring with a 2.4 liter 4 cylinder engine. The timing belt broke and I am planning on just replacing the entire motor with a junkyard motor..... There are 2 common types of the 4 cylinder engine in 2001 sebrings and 2 ultrarare ones.... Am I limited to just that specific "type" there is like X,B,S, and one other.... If my current sebring has a X version do I need another X version? and do I need a 2001 sebring engine if there is an exact same 2002 sebring engine( i was told that wouldn't work because of the electrical system)

Thanx for the help.
