I honestly would get a legacy turbo waterpump with the neck because the wrx one has three coolant nipples on them where two you won't need if you don't have a oil cooler and the other pipe that goes up the front of the block torwards the back and crosses over to the passenger side and connects to the water pipe the wrx has attached on the passenger side manifold.

I'd have to wait until i go home for the part numbers...
