I've ran several. Which model are you running? GT37 and larger frame, the Garrett powermax water lines are hard to beat. I've got a GT30 on it now. Some 90 degree fittings to 5/8" barbs for the coolant. Went from the heater core, turbo, back to the coolant inlet at the block. This wasn't the cleanest install, as it was only supposed to be temporary to see how it performed. Two years later, its still there.
