Question about replacing Engine... (2005 Aveo)

[FiXXXerX]

So my roomate had her timing belt go out on her over the Christmas break, the engine is pretty much beyond repair and replacing it is the smarter option (The engine had around 115k miles on it). I've been looking around and most engines I've located near me for a 2005 Aveo are running between $1300-$1800 ... all for engines that are very high mileage.

But I did find an engine on E-Bay that is from a 2007 Aveo for a far more reasonable price... but my question is: Will the engine from a 2007 Aveo fit and run properly in a 2005 Aveo? I did a little bit of research and saw that they switched up the front facia and did some other little things to the car and that the engine may have been replaced with a EcoTec engine... so if I pull the engine with the ECU from the 2007, would I have any problems with installing it into the '05?

Any help would be appreciated!

Thanks

** EDIT ** Looking at the picture of the engine that's for sale on E-Bay, its an E-Tec II ... which seems right, right?
