So I'm looking at what to put on my 20B in terms of waterpump housings and waterpumps; is there any flow difference between the NA and T2 waterpumps of the differing years?

Originally my plan was to use the FD housing but I don't like how far forward everything ends up sitting. Ideally I'd use the S5 NA housing and pump which I have new laying around but was concerned about the flow differences.

Does a T2 pump bolt to an NA housing? I noticed the visual difference in the NA and T2 waterpump housings is an extra coolant inlet at the bottom.

Please advise!

i think the only difference between all of them is the plastic filler necks on s5's and the TII's have a water return for the turbo, and thats it, from looking at them

S4 and S5 Fan Hubs are different, too... if that's the right word. Where the fan would get bolted on, the centering piece that goes into the fan is larger on the S5.

Should a 13B water pump be used on a 20B? Is it enough? I have no idea, which is why I'm throwing it out there...
