I'm finally replacing the old junkyard turbo, and the one I wanted ended up being water cooled.

First off, where is a good place to run the water lines off of?
Second, let's say I wanted to hold off on the water lines... how important is it to have the water flowing through it? Can I just leave it open for now?
Finally, are there any recommended fittings and such?

Thanks a bunch.

I would defently not leave it open. I'm not for sure on how to run that with watercooling, probebly from your heater core or something, but I know that those turbos create extreme amount of heat and running it open like that is a big no no


**changes are here**

running it open would be like running a regular non water jacket turbo... the coolant just surounds the center of turbo absorbing heat like it does in your engine block. i ran mine from the top of my engine (near the breather) to the turbo from the turbo to the overflow tank (it runs under the engine).

Thanks for the info guys.

Just, the most important thing is to know if I can run it just oil cooled for a week or so without damage. Either way, I'm not gonna push it hard, and I'll turbo time, etc.

Any idea on where to get water from in a 2.4, too?

my nissan T3 is setup for watercooled but i never hooked it up and its been fine for about 10k + miles now. depends on your setup but you can run your turbo without them hooked up forever. The water jackets prevent long term damage and turbo life and lowers the threashold ALOT on coking the bearings (which makes it almost impossible with it watercooled to do).

We did a Lancer 2.0 turbo and used a Nissan 240SX turbo that was oil and water cooled. We only hooked up the oil feed and we havent had any problems.

If you have a water cooled turbo, why not cool it? my suggestion is to get the coolant fron just after the radiator, thats where the coolest water is, then the outlet should go just befor the radiator. That really is kind of a common sense kind of thing. A water cooled turbo is an excelent design and will help the turbo cool a lot. My 90 probe gt which came stock with the water cooled turbo is boosting 12 psi at 144000 miles it is still running. You hear all the time that turbos are luckey to get 100,000. that just goes to show that water cooled turbos are by far superior in the durability standpoint.
