Its like sticking half your hand out the window vs sticking all your hand out the window. Only half your hand actually gets acted on by the wind in the first scenario.
Look at them side-side. The details are not immediately apparent.

Misinformation comes from frsport.com (

I wish I read a little more before purchasing the s14 pump.
I was having my car tuned over the weekend and we saw some knocking around 4-5000 rpm. We had to end the session early.
Looking back, I'm wondering if the water pump may have caused problem somewhere and brought the cylinder temperature up.. Coolant temp was fine. Regardless, I'm changing the pump back to s13 one and going over the car to find any issues.
