there are 2 ports on the oil pump case that were casted for a water pump, i dont know of anyone that has installed one there though, but the kit your looking at seems interesting to me, i may have to try one some day, they give you an external pump, and a hella nice radiator too, i like it, and think it would be worth a try, back in the 90's there were ones called or by a company "cool head" i believe, but they seemed to fall away, but i've seen ones for the banshee's all along??? some temp readings before and after would be nice
