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?
Thanks!!:D

The Daytona also has a better bottom-end to handle the extra horses - forged pistons, shot-peened rods & crank & nikasil liners. Other than that its all about the cams and exhaust

Your swap from S3 to Daytona will be pretty straight forward on your bike.
Complete motor, headers & exhaust (both!) and oil cooler will be required. The oil cooler is bigger but uses different fittings on the crankcase. (the 1050 is the same so can use that cooler or Daytona one)

Then you just need a Daytona tune in your ECM and you should be good to go!

1050 is also physically same - less hp than the Daytona motor however.
You might need a lot more things for 1050 swap - airbox is different, idle control is different - ECM is different so would have to either swap entire harness/control system/ intruments etc or make the sensors work with the existing system - should be doable, need a Tuneboy for sure! Might be easier to replace the TB's and idle system off the 955 motor? (not sure about that last part)
