There has been a 2.2 16v built by a company a long time ago, although i cant remember who built it, all i can really remember is that it took a lot of time and was built differently around 3 times and they named it after a ww2 german plane
It runs throttle bodies i know that as they couldnt get the fuelling from the k jet, if i can find any more info about it i will let you know but its either buried in my flat or in my mums attic
But to answer the original question it wont be standard 2.2 and the chances are it wont be a modified to a 2.2
they did do a 2.0 16v in a passat though which i should imagine is what it is
