87 eta to 89 i engine swap, help?

Another great question, and i was having difficulty finding direct answers to my issue...Swapping an engine from an 89 325i into a 87 325(e)

Basically i found a problem with my engine which i wont go into, but it needs to be replaced. Also, luckily i found a really cheap 89 325i engine from a friend who doesnt want to fix his totalled car. basically, my questions are

What do i need to change in my 87 to accomodate this "upgrade"?
Should i be worried about any small problems (anything i should know)?
what else do i need to swap besides the bear engine?

I know, most people probably would want to swap for an even more powerful engine, but i really care more about getting my car running again. I mean, i could honestly go out and buy an e36, but in my opinion e30's have a lot more character, especially if maintained well ; preformance isnt much of the issue for me.

You'll need the computer harness, computer, radiator (different/better hose placement), and the instrument cluster. Make sure that the A/C compressors are the same. You may need to splice the DME power supply. The only thing I'm unsure of is if the 13 button OBC will work with the 89 DME.
