ok, i have twin 54mm garretts on my truck(5.3), and they are almost ready to be fired up. one of the last things i need are to run the lines for oil.
how much oil can do i need? 60+ psi is too much right?
im using -4 feed line and -8 return
Thanks,
Dan

 

60psi of the engine will be fine.
4an is good, but id use 10an on the return.
you need a good return system and i dont think a 8an would be enough

 

What smokinnhawk said.
I bought two 12 mm flex steel oil return for my T62s. Its a Mercedes Actros Truck oil return line

 

thanks guys, this is my first turbocharged vehicle so i really dont want to screw it up.

I would suggest 3an lines... with that pressure and volume you will most likely develop oil seal problem. many people are using restrictors on the pressure side. turbos only require 10-20 psi of pressure...

 

I have also heard 60 is too much $.02
