Kelly,
In the car, the upper port is for oil in, lower port for oil out (of the turbo), OUTER port for water in, and the inner port is for water return. I copied that for my installation. I think it is important the keep the oil top and bottom for oil drain purposes.
I also copied from the car where I get and return the water. In my case, there was a water outlet on the intake manifold that I was able to keep, including the stock steel plumbing, which made my installation really easy. That water comes from the engine block after passing across the hot side of the engine. The cabin heater water outlet, or taping the high pressure side of the pump would also both be good options.
For the water return, I also copied the car in that it is returned after the radiator and just before going into the pump. This means that the turbo water is not cooled before joining the circulation, but it will have a much higher pressure differential than if it also had to go to the radiator. I figured they knew what the turbo needed so I didn't change it. Given that the turbo is probably one of the shortest lived components to start with, it makes sense to keep that water flowing. But apparently it does not matter if the water is pre-heated a little (by going through the hot side of the engine), which also makes sense because the turbo is so hot that it will still have a nice temperature delta anyway.

Girrrl's,
Still working out my turbo water plumbing.............But planned to plumb into the water pump
housing (pressure side into engine) to the turbo and from the turbo to the pump hsg outlet to
the radiator............. I did read in "Turbonetics" installation instructions that you should plumb
cool water into the low port and the hot (return) water to the high port of the turbo.......I do not
recall this question being asked before so I am posting this to the group that are currently or
planning to turbo their projects............Guys jump in here !!

Kelly,
We're looking at cooling the turbo, from the schematics it appears as if they are feeding the turbo HOT water (high pressure is all after the pump) and returning it to the pump inlet, in effect recirculating hot water in a loop that is not seeing the radiator except in the mix?
How did you do your TO4?
