I'm planning out my approach and was wondering about oil coolers. Our cars have small sumps and I am not yet at the point of making changes to mine to add volume. I figured adding an oil cooler would help in reducing turbo oil temps. Of concern is the oil pressure on my 200. At operating temp and at idle I am somewhere around 10-12 psi. When moving it will get up to 40 psi. If I add an oil cooler, my concern is that the restriction may create lower pressure at idle. Does anyone run one? Is this a valid concern? Thanks.
