ive read a few things about being able to swap in other engines or heads and such. can anyone tell me more about that?

like what other engines (or heads) can i drop in my 82 celica without a lot of modifications.

2.4L 22R RWD Carbed sohc.

i found a few engines and heads on ebay. they say its a 22R or 22RE but from different years or from a 4x4 truck, etc. is there a difference between the different year 22Rs? 22RE? 4x4, does it matter?

ebay a good idea or not a good idea? they are not too bad in price, and some are rather close to me, which i could pick up and save a few hundred on shipping.

but the auctions end soon.
