That was me "slickchick220" I logged in with my girls name! Anyways..I've seen cars with over 400hp with syncro. I think even EIP's Golf is syncro with 600+hp!
You can fit Syncro system to a Corrado but it's not that easy. Labor extensive job. You need to cut the car up and weld the Passat rear floorpan to make place for the propshaft. Then fitting a fuel cell because you won't be able to fit none of the fuel tank under there. The best way to achieve this setup is the find a complete Passat Syncro. Good luck finding one.
So for the synchro swap, it's very hard, it must be the same same thing for the 4motion system right?
what about the QUATTRO system? all audis came with longitudinal engines, while VW has transversal so that's a pain in the grundle.....anyways, thanx for ur time
