Good luck with it but for what you will gain it seem pointless to me, Golfs are cheap at the moment I would have thought it would be easier to sell it and buy a Gti.
your right it would be easier and cheaper to sell the cl and buy the gti, but me and our kid have the dub bug and want to get our hands dirty mainly just to see if we can do it. We are new to this scene and we will love evry minute tinkering around the 8v is easier to work on and sounds like a good starting point to me lol a lot of you might think otherwise but you have to start somwhere and then go on to other things
