questions about FE/FD swap
 

I'm helping a friend with getting an FD. He's very intrested in them, but he's on a limited spending amount. He's thinking about getting an FD without an engine then swapping in an rx8 renesis. I know this is possible with enough money, but

A) is it worth it?
B) how easy is this swap? Does the 8 engine bolt up with the FD trans and motor mounts
C) Is there any extreme custom stuff that has to be done?

Thanks for any help I get here
