Here is an image of the inside of the waterpum placement on the SR20 block
As you see, it is a quite small opening for the water, whihc restricts the water flow. This opening makes a far less volume than the waterflow into the waterpump. So what I did to make sure things would flow good is to gently remove the "restrictor" with an airtool

Have you seen this done before with success? I am a little skeptical of grinding away part of the pump housing. I would be afraid of a pressure drop or something. I am in for the updates and data from your cooling setup
