Does anyone use an oil cooler for their turbo charged cars? I'm using one that I picked up at the junk yard. My oil feed line runs into the cooler and then into the turbo. I can actual hold the stainless steel tube that comes out of the cooler. The tube going into the cooler is very hot. I live in Wisconsin though and the temps get below zero sometimes. Does anyone know if the oil cooler can have a downside to it? And does anyone know what style coolers work the best, like the tube coolers that run back and forth through fins or the intercooler style ones?
