im pretty sure water definitely cools a ---- of a lot better than oil. oil only lubricated due to the adhesion to what it encounters, just be a pro and go to Academy and get a 500GPH pump in the boat section for 20 bucks like i did for my W/A intercooler.

On our race MR2 we used a rubber impeller type compact water pump for the water to air intercooler. Was cheap from princess auto, and works great! never had an issue.

I pumped oil with a Walbro fuel pump and it only lasted for about a week...lol
