Zerex G-05 coolant works well (as it does in all-aluminum Mercedes-Benz engines) if you don't want to shell out $35/gallon for Porsche coolant concentrate.
May as well change the thermo while you're in there since it's right next to the pump and you'll lose coolant anyway. Why do it later?
Avoid any pump with a metal impeller as that can cause engine block damage if/when the bearing goes out, while composite will not do that.

Same thing, I got a Pierburg WP and it has the Porsche part number on stamped on it.
I paid $190 for the WP, $52 for low temp thermo/housing/gasket & $3.50 for the WP gasket, no sales tax and free shippingh @ warehouse33auto.com
