I have seen numerous conversions of Audi 4cyl (2.0l) engines installed in VW
Rabbits or
VW Golfs. They were essentailly bolt-in convsersions. All of the conversions
I have seen
are on the A1-A2 platoform. There are a couple of small details to take care
of but nothing major
(eg Audi uses a warm-up regulaor whereas VW does not). . So I assume that
the reverse would 
also be true. . Transverse vs longitudal postioning of the engine has no
bearing, Essentailly the 
engines are same. I know of a garage in NJ who just did 2 conversions on a
A1 Scirocco and 
and A1 Rabbit.
