I think 07VTRex is right... its not a matter of IF it can be done or if it's plausible. Everything is possible and has been done. However, it's just not financially worth it at all. I know someone locally who is going through this process right now, and has spent well over $7k and isn't even close to being done yet. Mind you, he pulled his v9 2.5i engine/transm. and put a v7 STI full block and 6spd STi transmission as well. I think by the time he's done, it will have cost him almost 8-9k worth (I'm not sure of the exact amount of cash though, mind you).
