I don't get the love for evans, but have at it i guess.  If you ever race somewhere that requires water you are SOL.  I just run 50/50 with a bottle of purple ice.
I'm using a Stewart stage 2 water pump.  180* stat.  I just use a basic high flow Robert Shaw style stat.  I tried the Stewart one with bleed holes and my car would not heat up so i put a regular one in. Not sure if i got a bad one though. 
Why not the 3 row Mishimoto?

My car never gets hot.
I'd give each relay its own link so if one fails the other fan still runs.
Are there covers for all those exposed hot terminals?
