J160 1G-FE gearbox to a 3SGE?

[MostWanted93]

Hi! Been searching all night but cant find any answer.

Is it possible to mount a J160 from a 1g-fe IS200 to a 3sge?      
I did find like a million other threads people asking the same thing, and most of them got the same anwer:
"No, not without some work"

What kind of work does it involve?

The reason im asking is because the 1g-fe IS200 gearbox is available here in Sweden from around 150$, the RS200 J160 is a little bit more expensive, and not available here at all. So thats not an option, neither is buying the right bellhousing and change it.
