Aftermarket oil cooler tank.

I think I want to add one but have my drain for my turbo go into it. Just not sure if the turbo would drain into it as it's gravity fed. Any thoughts? It's currently feeding into the side of the case.

Should work, there is not much if any pressure inside the oil tank as it's vented.

You might be better off putting the cooler in the pressure side before the turbo bearings. I would guess that the smaller turbos for sleds are built the same as larger ones for cars/trucks, but I also was interested in doing that on my Cummins 24v a number of years ago, but Holset told me to not restrict the drain tube in any way as it will cause the seals to fail and the turbo would start pushing oil into the engine.
I thought it would make the most sense to cool the hot oil from the turbo before it gets back to the engine, but aparently that was a dead end. They told me the best way to add an oil cooler was through a remote filter mount, but again, that was for a truck, not a sled.
Just a thought, might be worth some homework.

Restictions of oil feed lines to the turbo should always be in front of the turbo for the reason nate007 gives.

Oil pressure inside the turbo could cause bearing or seal failure.
Failed seals can cause the engine to loose a lot of oil in a very short time, With possible engine failure pending.

Ok maybe I didn't state what I want correctly. Like how mpi superchargers comes with a new oil tank. Something like that but an additional port for my turbo drain. Maybe i'll contact OSP and see if they can make me a custom one.
