read my signature.....if you want your turbo to last an reasonable amount of time i suggest hooking it up

oil cooled turbos have large oil passages that not only lubricate the center section it helps coo lthem off aswell

watercooled turbos oil passage is just big enough to allow the oil to lubricate and does no cooling whatsoever, so it has a coolant passage that allows your motors antifreeze to do all the cooling.....so with out water lines you will cook your turbo

Run the water lines for sure. Even if you wait a while before shutting it off you should still run the lines.

Run the cooling lines and don't forget to run the cold/inlet to the lowest part of the turbo and the hot side to the upper side, it will help wick away the heat after the engine is shut off.

Another big advantage of water cooling your turbo is the fact that you dont need to let it idle for a minute before turning your car off.

I water cooled my 42/48 garrett without any issues and the turbo worked flawlessly.
ive never let any car ive ever boosted idle for a minute before turning it off


its not 1981 anymore broski, oil is much better today.

Oil still breaks down danz. Conventional degrades at 250 degrees, blend 300-350, and syn 350-400. A turbo actually depends on high levels of heat to function properly in the 800+ range. This creates heat soak into the parts and if the oil does not cool properly it breaks down into a hard sand like substance that clogs oil ports to the vital areas and will create excess wear. Even watercooled turbos can benefit from a turbo timer.

On the t3t4 the oil Ports are not very different from an oil cooled turbo compared to a watercooled. They can be safely run strictly oil but highly suggest using the water. Where you run into issues and need watercooled is with smaller frame turbos like t25 or under.

Using synthetic is best. Synthetic does not have the natural occurring impurities like sulphur that can oxidize metal when oil breaks down. Oxidizing creates excess wear. Not only is super heated oil bad for the turbo but its extremely bad for the motor as well.

The primary purpose of oil in a turbo is to cool it down and keep it at a safe operating temperature.

Was this whole fight posted somewhere else?
Water cooled turbos have a the ports and space for water to cool the center. The oil passage is normally very small.
While oil only turbos have a bigger oil passage to help cool. Not bigger holes. Will put it like this, a watercool turbo holds less oil then an oil only turbo of same size.

There really is a post on here that has links to pix of all this.

And dan a turbo timer is always good to lower the temps befor sitting. most of the oil will drain out of the turbo when not running so the turbo stays hot and tranfers the heat to the bearing.

If I listed cut away pictures of the t3t4 bearing housing members would still argue about it. Sometimes I guess its best to accept that what you know from your own experience and facts is just a figment of your imagination.

The oil inlet is no larger on either type and it restricts flow.

One more time the only time oil passages are any smaller is when size is a restriction like with smaller turbos. This its why you see most OEM turbos watercooled. Also smaller turbos are more likely to heat soak due to their size.
