So far all the instructions I've seen regarding drilling the block for the oil return have basically just said "drill the block" and that's it. Are there any write-ups on how to drill the block, how to get the hole threaded, etc? I'm pretty confident that I could to the turbo swap pretty easily, but tapping the block is the only part I'm worried about. I know that metal shavings need to be removed by flushing with mineral spirits. Is that just pouring the spirits into the new hole? Should the oil pan be removed while all this is going on to protect the internals from the shavings?

Also, I forgot to steal the downpipe (exhaust that runs from the turbo to the cat, right?). Can I run the car without that if I have to drive somewhere to pick it up? Or is the lack of backpressure going to mess things up?
