I got an 89 TII and I want to swap out my water pump housing for an s4 one because of the better non plastic thermostat elbow. The problem is my car is turbo and needs that nipple that comes off the buttom of the housing where the lower radiator hose is. I got a bunch of s4 NA housings and I want to use one of them but I need that nipple for the turbo. My dad is a welder so if I could find that nipple somewhere he could weld one on for me. Do you guys know any places that would sell something like that?
