Engine Swap/ Odd Swap

[carlos1787]

Hey All, I 'm looking for some info on doing engine swaps. I know that some odd swaps are possible. (ie 1990 2.0 4 cyl (3sfe) will work in a 1995 that had a 2.2 (5sfe) with little work). I am wondering specifically about the 1997 to 2001 series. What engines will work, and how many parts need to be reused. I know that using an older (pre 96) 5sfe in a 1996 camry requires changing the oil pump housing, and rerouting the Idle Air plimbing. Any Info would be helpful.
