is it okay to use a non water cooled turbo?

In my long quest to find a matching turbo that came on my TC, an Airesearch M11, the only one I am able to find doesn't have a center section that is water cooled. The link is here: http://www.ebay.com/itm/Garrett-Turbo-T3...b1&vxp=mtr

Is it okay to go with oil only? Also, is there anywhere online that has a good selection of turbos that bolt right up to TC's? Thanks.

I personally prefer oil and water but I did run a oil only t3/t4 turbo for a couple years without any issues. When I removed the turbo it was still in great condition and that made it easy to sell.

That ebay turbo has the wrong exhaust outlet pattern on it. Not sure if that can be changed or not?

I'm kinda leery of going the oil only route but I'm having such a hard time finding one with that two bolt inlet that attaches to the compressor housing and when I do find one it's the non-intercooled style outlet. From what I've researched the water cooled turbos prevent oil from coking inside the turbo. I don't drive my car hard so I don't know if that would be an issue. Anyone know where I can find a good turbo for 500 or less?

Run synthetic oil and let the car idle for a minute or 2 after "spirited driving" and you will be fine without water cooling. If the last few minutes of driving were "normal" (sane) driving, the minute or so cooldown isnt needed.

I've got a non-water cooled T3 from an SVO Mustang and haven't had any issues. But like Jeff K. advised, I run synthetic oil and always let it idle for a couple of minutes before shut down.

P.S. Don't forget to block off the water lines if you go the non-water cooled route ! lol

The idling for 2 minutes is to prevent coking of the bearings in the turbo. Coking occurs when the hot oil burns (actually cooks) to the bearing surface due to excess heat and no oil flow (after shutdown). Use of synthetic oil prevents coking on the bearing surfaces, but idling the engine and letting the coolant and the flow of cooler oil to the bearings is good insurance.

I always run Mobil 1 full synthetic. I just wanted to set my mind at ease, which you all have, if I had to go the oil only route. Pete, if I'm not mistaken that is a five bolt flange with a different exhaust outlet bolted to it, correct? In any case I emailed him to see if he'd send me a pic of the exhaust flange.

I wondered about that but I think there were turbos made that couldn't be adapted. I agree on asking for a pic

I agree with letting it idle for a minute or two before shutting down. I use to always do that and that's one of the reasons I prefer oil and water. However I always thought that synthetic oil wasn't good in our engines unless you swap to a roller cam.
