Hi, its a s5 street port with tdx61 going into a s3 1st gen, prolly not the appropriate section, but then again, it does only have one turbo!

So im just wondering what is the preferred water line route for the single turbo crowd.???



My previous setup (before engine rebuild and new turbo) was getting supply from right side heater hose from firewall, and returning to lower water pump inlet.

Im not sure whether to do it this way again, or if there is a better way.
