Interesting reading.

I heard of the Ford Tauras fans being used...

Don't know if they are good or not. 

This is the best fan out there guys. I kidd you not. Dont waste your money on any other fan. I love mines and it fit like a charm on my 22re. its a 2500 cfm on speed 1 and speed 2 is 4500 cfm or so. way stronger than any aftermarket fan out there. if there is an aftermarket fan out there rated for 4500 cfm or so, its never correct or its $300+. This thing is awesome. If it would fit with my 1uz swap in my T4R then I would have kepted it. it cost me $15 for the fan and $10 for wiring and relay. Autozone or any auto parts store has a external temp adjust probe so it will turn on at any temp you want. If you go to the junk yard you can even grab a relay from any car and wired it up. This is the best MOD ever for the cost. I even wired it so I could have turn off the fan when I cross rivers.. Junk yard has so many of these fans laying around. I ran into 6 just last week here @ fresno pick a part....
