Oil Feed, Return lines?
 

I'm new to turbos... i'd like to know really quick, what role the "Oil Feed, and Return lines"... like if I were to go for a custom turbo setup in the future.

ummm. the oil feed lines run oil to the turbo and the return lines return the oil.

or were you asking about how you would run the lines with a custom turbo?

yeah, how would you run these... where do they "tap" into, or whatever..

on my civic you put a 3 way tee fitting on where the low oil indicator light sat at..that was the feed line. for the return, you'd drill holes in the oil pan and mount the flange there. No idea how you'd do it on a ka though. good luck
