2.0 to 2.1 or 2.2, who does it?

just wantd to know which companies offer to bump the displacement for the 2.slow. would be a cool thing to see if it doesn't cost too extremely much, for too extremly low gains...what kind of gains can u get from that? same thing for the VR6, i know some places that do it, but how much power does it add?? :dunno:

je sais que luc chez l-port avait un sirocco 2.1l 16 valves cale them.....
