Can someone who has experience with this please shed some light on what would be required to have an engine conversion(replacing my existing 1.1 with a larger engine from a different model)

A list of what needs to be done/replaced would be perfect. Cheers.

well i guess its for a punto?so instead of the whopping great punto section you go into the bodyshop section.
are we talking the engine from a harrier jump jet or another punto?
