T3/T4's dont' have coolant lines (although i'm sure there is an exception). Most turbos that have coolant passages are ballbearing or huge. Also i think there are a handful of factory turbos like 14b's that are water cooled as well. You don't have to water cool the turbo if it is that big of a hassle, but it is designed to give the turbo as much life as possible.

T3/T04's like mine don't have water ports...
