u cant run the return back to the oil pressure fiting because it has 0 pressure after the bearings in the turbo.

 

I know it's sorta been answered, but I'll give it again in another way.
...you cannot tee the return to the oil pressure fitting because it is under pressure. meaning it'll 'push' oil toward the turbo just like the oil inlet line.
There will be no flow through the turbo.
IF you are thinking ' well why not? the oil goes in one side and out the other side. It would do that if the turbo wasn't there anyway"
you have to realize that the turbo 'oil bearings' will really restrict the flow

...now if you want to just 'tap' inline for water cooling that's ok since the water/coolant will just flow through the turbo. .

 

what about a sandwich adapter for an oil cooler. it has an inlet and outlet then some sort of pump to pump the oil back up from the return.

sounds like more effort than it's worth, but if you can't rotate your turbo to fit with ac or get a manifold that will allow you to still use your turbo and ac together.

 

Dubmonkey takes the fucken cake for that one. His first post and he's explaining ---- for people. He just totally skipped the "what's a turbo" question and went to breakin' it down. Just thought I'd share my observation Nice. Welcome to the forum
