I was wondering if you could run an oil cooled turbo rather then the water cooled turbo. I know that the oil cooled is almost everywhere on eBay, but I didn't know if you had to run an oil cooler before you put it through the turbo. Or what you would have to do. Thanks.

oil cooled turbos are just fine, search is your friend.

If you use synthetic oil and/or let your motor cool down a little before shutting it off you should have zero issues. The water cooled turbos are mainly for cooling the oil by convection when the motor is shut off hot, so it helps "normal" people have no issues with coking of the oil. Meaning all of the people who dont understand this that bought a factory turbo car and dont wish to change there driving habits.

You will read about people that use only oil on "water cooled" turbos w/o issue

Wow, I guess that really explains it. I never knew why there was a difference. I always thought the water was ran through the turbo to cool the turbo down, not to cool the oil. So by those standards, you could actually remove the water lines to the turbo on the turbo's that are stock on TD's and as long as you let the engine cool prior to shut down. But I was wondering, what temp would be the best to shut the car down at then? Just regular running temp or how low?

Thanks, I really feel dumb when it comes to the turbo's. I have been raised around N/A engines, and I am the only one in my family that even looks at the use of turbos. Thanks for all of the help.

its not the coolant temperature that is the problem, but the turbo temperature. they usually dont have alot to do with each other. the main problems is people that run crappy oil, and pull right off the interstate into a gas station and shut it down. if you drive even just a few blocks in stop and go traffic after getting off the interstate, thats enough to cool it down.
of course this doesnt even really apply if you use a good synthetic oil.
