Will this setup work (please read)

[crazy_camry]

i'm wondering if this would work, and what peoples thoughts and improvements could be. would the coolant flow sufficeintly? Note this is a 3s-fe, using a CT-26, and ST205 oil cooler. The thick black lines are the proposed coolant lines.

My initial thougth is whats the difference in pressure drops across both the oil cooler and turbo?

Let's go to basics, the engine uses a water pump inlet to suck the water in. When it's hot you can throttle up and watch the lower hose get a vaccuum against it. Therefore there is no real amount of pressure to push it from the radiator and towards the turbo or cooler. I personally would consider a pump of some type to feed coolant to them. A suggestion on the turbo coolant return line is get a line from an airconditioner parts store with the heat sinks attached. I dunno if I'd want coolant that hot mixing back into my engine.

could someone be so kind as to do a quick sketch in paint or something to show how the lines should be routed?

Bump.

i can run supply lines to the cooler and turbo from the water bypass pipe, but i want to fit the return lines somewhere into the radiator hose before the radiator so the hot coolant can be cooled. if it were before the radiator though, would the coolant from the radiator hose want to back up the return lines from the cooler and turbo?

You can run the turbo non-water cooled just find. I know a lot of Subaru guys who run their water cooled turbos without water (with an oil feed still, of course!!).

If you get a chance, try to find how the lines on a stock ST165/185/205 are routed to the turbo and you can get an idea of where to tap the water from at a later time. You should only need enough water flow through the turbo to keep the water/coolant from boiling...

yeah i've been told that i can run it without the water and just make sure to shutdown properly, but if figure if it's ther i may as well use it.

i've been having suggestions where the hot coolant from the turbo doesnt go through the radiator before returning to the pump etc. Is this a problem? i can get a small cooler from work to put into the system before the pump to help cool the coolant a little if it would help?

also if the above is not a problem, what about getting coolant feed from the water bypass pipe underneath the exhaust manifold, and return into the heater pipe, next to the bypass pipe under the manifold?
