Water cooled turbos I have a set of CX racing 67mm chinese turbos on my build. They came with the tubes and Banjo bolts to hook up the water cooling system to the turbo. Anyone else running this? If so can you post some pics up please. Also does it matter if one side is a feed or return? Can i tap off of my heater hoses for this? or is there a better location to get the coolant from?
Thanks!
Thanks!

Protects the bearings after shutdown. There's a lot of heat that soaks back into the center section of the turbo, and when the engine is shut off, it's no longer cooled by oil flow. A lot of OE turbo setups take advantage of a "thermal siphon effect" to pull coolant through the turbo after shutdown, ensuring that it stays cool.
It's not really a big deal if this is a journal bearing turbo and you at least have enough discipline to idle the engine for a little while before shutting it off. If it's a ball-bearing turbo, it would be wise to hook up the coolant lines, since the innards of those can sometimes be more sensitive to this kind of thing.

If you turbos have them why not hook them up. I have seen some use a small electric water pump (many modern turbo cars use them). You can then keep he water following post **** down. This is what a lot of OEMs do now.
