s4 NA and turbo pumps are the same, and s5 turbo and NA pumps are the same, but s4 and s5 pumps are different. The bolt pattern is different. Also the shaft diameter, where the clutch fan bolts on, is different, making the fans also unique to series. OF course if the water PUMP bolt patterns are different, then so must the water pump HOUSING patterns, so those are also unique to series. Bottom line, don't try any cross series swapping of waterpump/housing/fan/thermostat neck.
