What is the diference between the 955 from the 2004 Daytona and the 955 from the 2004 S3? Is it all in the top end heads and cams? I see the bore and stroke and compresion are the same on both. Anyone know?? I am thinking about the extra ponies the Daytona has over the S3 and might be interested in doing a swap if it can be done. Also anyone know if the 1050 S3 motor will bolt into the 955 S3 and what is all involved in both of these mods?
