Lakenheath24, running the factory heat exchanger certainly won't hurt a thing. If it's already there, leave it in place. An oil-to-air cooler, when properly plumbed and thermostatically controlled, would certainly be better than the factory unit. Certainly not A MILLION TIMES better, but better. If you're going to run a turbo with no center section cooling, without an auxillary cooler or heat exchanger, at least put in an oil temp gauge to monitor the oil. If you find the temp running higher than you're comfortable with, put a cooler/heat exchanger on it.
