I have one on my Grandnational! It is a must on turbo cars! The turbo get over 1500* at times, oil is only good to 300* if your lucky, and unless you run a turbo with water going thru it, I run a oil cooler. I have a LQ4 in a 1981TTA with a turbo, and Im going to install the stock oil cooler. I install them all the time on guys cars that come here with low oil psi

Back along time ago when I was buying my first upgraded turbo for my GN I asked Harry H. @ PTE about running an oil cooler.
This was like 13 years ago and Harry EITHER told me:
1. The main or one of the main reasons for turbo failure is the oil being to cold
OR
2. He sees more turbo failures from oil being to cold than to hot
I cant remember which of the two he said, and I was really surprised when he said it. Keep in mind this is something I was told only one time and it was a long time ago. I would call PTE or Turbonetics and see what they say.

It can be too cold, but thats typically because the car got ragged on when dead cold, ie first thing in the morning. fire it up and let it run for a minute, even while driving cars on a chassis dyno, and motors on an engine dyno, the motor is always run for a period of time in order to bring the temperatures up to an acceptable level.
Saturday morning I was watching the powerblock on spike, they were running a motor on the chassis dyno that was expected to produce 604 or 605 hp. It didnt, they checked oil temp, 107*F, too cold. ran the motor for a bit to bring the temp up into the 170's, 604hp.
