I have a 01 outback Wagon I am turboing and need help on location of recommended location of oil feed and return lines to engine block

Best bet is to find an actual turbo'd short block and use the locations it's using. Save yourself the hassle and run a turbo'd oil pan with the drain back already attached. I know my oil pump has 2 or 3 threaded plugs running off the oil pump housing. I believe at least one of those should be able to supply oil to a turbo. Also, make SURE you run an oil cooler up front to help prevent oil coking, especially if the engine doesn't have oil squirters. AND make sure whatever turbo you end up using has an oil restrictor if the manufacturer calls for one. Some turbos don't need one or have a restrictor hole already built in to the CHRA's oil feed. MAKE SURE you use OEM or high temp oil resistant hose for the drain back (like high temp silicone and don't be cheap). If you use sub-par, or non oil resistant, it'll swell over time and rupture, and within 30 seconds your engine will be toast.
