turbo return line size?

[IDIeselman]

Since I have to remove my oilpan to replace some seals and gaskets and planning a twin turbo set-up in the future, I was wondering what size orfice I should weld on the side of the oilpan for future oil return lines?
thanks Tim

With the big hole availible in the valley pan, are you sure you even need one in the oil pan?

I didn,t know thats where they went. But I plan on two small turbos on custom manifolds mounted level with the top of the valve covers with braided stainless lines going down to each side of the oil pan. I was under the impression that a turbo has to gravity return and will not pump oil to return.

the factory ones were gravity--
