my buddy went this route, and he needed one big god dam oil cooler. were talking like the whole front of his car. it was outta a f-350 or something crazy. reason being is the tubes in the condenser are really big.

if u could find a small radiator out of a mini or something that would work best, because rads are meant for water while a/c condensers and oil coolers are not meant for water. good luck running all the hoses and mounting the pump and res!

sounds like a project
