Swapping S5 N/a water pump for S4 N/a water pump.

given I have the whole housing/pump/t-stat/filler neck can I swap them? My 89 GTU just starting pissing coolant from the lower weep hole and I got a great S4 pump sitting at home off of my 87. What problems will I encounter?

S4 -> s5 you have to change the front cover. I'm pretty sure the same is true for vice versa.
