For those of you that don't want to weld a bung /can't/don't have the pipe taps to do so. This is the probably the quickest easiest way to tap your oil pan for a drain back from your turbo...
Jegs part number 555-110562 -10AN Bulkhead fitting. $19.99
Step drills/knockout drills about $20
Measure down 1/2"-5/8" from the bottom side of the pan flange and drill pilot hole.
Drill hole to 7/8" dia.
Test fit bulkhead fitting.
Put a little silicone sealer on the threads and insert into pan. Tighten.
AFTER CHECKING AND DOUBLE CHECKING AND THEN CHECKING AGAIN FOR ANY METAL CHIPS , FOREIGN DEBRIS (AND MAKING SURE YOU DID TIGHTEN THE FITTING)...
Go put the pan back on
Total time after pan removal and clean up (and taking pics) about 7mins.

IT IS VERY IMPORTANT...
That you MEASURE for yourself, before drilling. The oil drain locations for auto and manual can be VASTLY different. Also, MAKE SURE that the oil is NOT dumping out on your balance shafts or directly at the shaft housing.

You are correct

. I should have put some kind of a disclaimer in there.

Yeah you're not gonna love that straight fitting so much - a 45 degree or 90 degree would be a lot better for a shorter gravity fed line.
Either way good writeup as always Gary.
