G60 blower will be doing very little on a VR, G40 was deigned to work with engines up to 1.6, G60 up to 2.0, not that good a supercharger these days, needs rebuilding every few years, tech has moved on a long way so cannot see the point in using one.
If it is in a mk4 the loom will need lots of work to work in a mk3, none of the mounts will be any good, all in all sounds like a complete ball ache.
Is this on ebay???
