The 2003 has a 28mm OD hose, so I would imagine the 2004 is the same. That being said, I would just use your TB lines instead. Just pull the top hose (the return line) off the TB, run your turbo water feed line from there and then plumb the water return line from the turbo back into the water neck on the head. Like this:




I changed my setup later on, but this works just fine.
