Engine Oil Cooler

Been wanting to add an engine oil cooler to my turbo 318 setup but am second guessing it. I have a 3 way oil pressure feed next to the distributor that feeds my turbo and my oil gauge. Wanted to add the oil cooler from here and dump it into the timing cover plate. Been wondering if I could starve the turbo from oil if I add this cooler. I just have a stock pump with a hardened drive shaft. Anyone running a turbo and an oil cooler??
