Return Line Size for SC61
Just started putting together all of my lines/fittings/etc for my turbo setup and realized that I have -8AN line (1/2") for my oil return. I know typically guys run -10AN lines (5/8") for the return. Will I be alright?

Re: Return Line Size for SC61
when gravity draining bigger is better, you need to run a -10an on a journal bearing even if running an oil restrictor, -8an is fine on gt/ball bearing turbos due to alot less oil volume

it's a journal bearing turbo with a straight down drain and obviously a gradual curve into my oil pan, which is tapped with a 1/2" npt fitting. this sucks. now i have to buy new lines and weld another bung ti my pan. fuuuuuuuuu. thanks though guys.

If you have a threaded bung on your oil pan, just buy a 1/2npt-10am adapter. Dot need to have the whole oil pan redone

Re: Return Line Size for SC61
I run a -8AN return on my SC61...
But then mine does smoke a little on decel... I don't think that is really due to the return line size as much as it needing some new seals. I was going ot try to switch to a restrictor fitting on my oil inlet before I bit the bullet on a rebuild cuz it doesn't smoke all the time.

I just finished my setup too and redid my return line and I still have smoke.
What size feed line is everyone using? I'm on -4an with no restrictor
