f4i to 600rr swap?

Hey I've heard of a couple guys that have 600rr engines in their 02 f4i's and dont know if its just a quick plug and play deal, or requires extensive modifications?? I found an 04 600rr engine with below 5k on it. I'm thinkin about maybe doing that to my '02 if it isn't a complete hassle. Any help or ideas are appreciated, Thanks!!
