I haven't strated this yet as this is going to be my first conversion and build. I am looking to get an S3 b lock and head then starting the build with this. What I have started this thread for is to start with the getting the advice as to what would probably be the best mods. i.e. cams, pistons, boring sizes etc. Any information would be great considering you are they guys with the knowledge and looking at these threads puts my confidence in your suggestions. Cheers in advance.
