The oil return is the biggest pain yet pretty simple. the hard part is you have to take off your oil pan and drill a hole and weld it. First thing first, make sure you drain the oil before removing the pan. To take your oil pan off, first you have to remove the center beam. remove the bolt for the motor mount, and then remove the 2 front bolts on the bottom, the 1 bolt on the bottom in the middle, and 1 more on the rear end of the beam. should come off then. there is also some tranny dust protector that must be removed. now just remove all the bolts around the oil pan and it should pull off. Now you must drill a hole in the oil pan, and i bought a 1/2 to 3/8 bushing, and welded it into the pan. i drilled where the HRC instructions say to drill. (

Now the oil return on the turbo is the one piece that cannot b bought at home depot. it needs a flange and gasket and bolts. this is one thing the oil kit did deliver on. but otherwise, the inside of the flange has a 1/2 NPT male to Barb fitting. I used some thick heater hose from carquest and clamped it onto the 2 barbs. be careful welding the bushing tho, mine still leaks. now for re-installing, some people replace the oil pan gasket, but its expensive, and designed to be re-used so i just re-used mine. put a little rtv by the oil pump when you re-install the pan... yes i know thats an ugly weld, but i was trying to fix the leak lol.
All of step 4 can be done and was done weeks before the turbo went in. as you can see in the second pic, there is a plug in the bushing. i also just put a cap on the end of the SS feed line.
