3S-GTE Guys.......Oil Cooler users within please. Options

[Fastbird]

So after finally picking up an oil temp gauge, I'm noticing a pattern that I DON'T like. My oil temps are hovering around 220° during normal driving and for the short 7 mile blasts I go down the highway, they climb into the 230°-240° range. This is being light on the car.

I have a feeling that it would DEFINITELY benefit from an oil cooler. So my question for you guys is how are you plumbing the cooler into the system, and what kind of cooler are you using.

I'm looking at two different styles of transmission coolers available at my Auto Zone that I work part time at. One is a simple tube running through fins, like the cheap ones you see. The other is like a minature radiator, bar and plate style.

My thoughts on where to plumb them in are initally to come in on the drain side of the turbo and use a scavenging pump to move it through the cooler back into the pan. I think this would provide the greatest amount of efficiency but definitely NOT the best cost margin. Other than this, I can't think of where to plumb it in.

And for those wondering, I have the temp sensor for the gauge mounted in the filter sandwich adapter with no problems noted.

Any pics, write-ups, or ideas on setups you guys might have?

I'd run a thicker oil as opposed to a thinner oil in a turbo car. Heat will thin the oil out and you can easily see a pressure drop from that. I was running a 20w50 last summer for a short amount of time. Other than it tanking a couple seconds for pressure to come up on startup I noticed no other effects and a slight bump in hot pressure at idle.

Sounds right to me [Pressure bump and time to come up]. Should also help the wear a bit too. My only concern is that Turbo wasn't rebuilt at the time and it may have some oil coking already and I'd hate to starve it.
Anybody think I ought to switch to Mobile1 but stay at 10w40 at least for a little while longer? I'm thinking I should probably just hang on to the 15w50 until the dead heat of the summer when it will need it here - badly. More 3S's die in the summer here than any other season I've noticed [MR2T friends and past experience]. Could just be coincedence but IDK.
I just want my girl to receive the best of treatment.
