I just bought a T04Z kit from the Rx-7 and there are no instructions. My question is, which is the oil feed/return and which is the coolant feed/return on the turbo itself?

Or does it matter which way the fluids flow in the tubo?

 

huh? you dont even know which is which? the small line is the feed line, the bigger line is the return oil line. come on man?

 

I figured that. So, what about the coolant lines?

 

Oil feed is the small hole on top and oil return is on the bottom. The coolant feed is on the sides.
