Look up eurowise on the vwvortex. They did this swap into a rabbit last year… Using mostly hand fabricated floors/strut towers. It is not for the timid. I’m probably going out on a limb and being an ass, but if you have to ask how it works, the swap might be a little over your head.
Maybe you should start with a VR6 or 1.8T swap if you feel ambitious. Researching that kind of swap and getting valuable information can also be done on the vwvortex, plus those two motors are readily available and the swaps are common so you will get lots of info.
My only advice is to use the search button more then the post button, and you’ll be ok.
