Maybe a little more oil volume. I haven't decided if I will or not.You certainly can. On the other hand, most of the aftermarket turbo kits use a 1/8" NPT port for the oil feed and have no problems at all. It seems like a lot of work for no gain to me.
Honed the block and checked all the ring gaps today. If I'm going to drill, it will be tomorrow before the final cleaning. One advantage is I won't have to find new line fittings for the turbo when I swap the rebuilt engine into the truck.
