I can't seem to find how to mach up coolant lines to the turbo. Wondering what lines and where, also does the coolant ports matter for feed/return.

also since its ball bearing. does it need oil restrictor? i'm going to be running a -3an oil feed line.

 

It needs restictor which it should come with. Check out synapse motorsports or B&R for coolant lines.

 

it kinda looks like there is its own restrictor in there.
