OK So don't laugh, I am a beginner.

I'm putting in my AiResearch T-3 .63 a/r
For the oil feed/return flanges, there is a square inlet/outlet and a round one. Which do I connect the feed/return to?

Thanks for any help!

 

the round hole on top( may be threaded )is the oil feed inlet, the larger squarish hole on the bottom is the drain.

 

Is that the way that the garret turbos are set up too? (like a t3/t4)

 

Yup

 

cool...thanks man!!

 

Thanks guys! I dunno what I would do without this site
