I would really like the oil temp to be 210-220* during normal operation, so a thermostat is in the planning stages. I may go with a Mocal, but the CV part is really nice.
No matter how much heat turbos may add to the oil, if the oil is overheating a cooler is needed. Worst case the cooler will delay the onset of overheating, but the amount of oil a turbo uses is much smaller than that used in the rest of the engine, which creates a lot of waste heat during high-horsepower output.

Carl,
Was this with your old engine with cooler and radiator inlet on the same side? The LS enters the pass side right?
The way it should work is the oil heat exchanger should be on the radiator inlet side tank receiving the warmest coolant. I'm getting a Be Cool rad and it's double pass, they have to put the exchanger in the pass side tank.
Thermostat valves take up a bit of room especially with all the extra plumbing. The cleanest way would be to have it on the engine block. I don't think you need to actually shut off the rad cooler and open the bypass. I think just opening a bypass would be enough, the cooler should have enough extra resistance to flow that would not allow much flow thru it when the bypass is open.
