I added a oil temperature sender to the dry sump tank for the GT-R. The sender used on C6 and C7 dry sump Corvettes is AC Delco #213-4333 (GM#12608814). This sender is the most common size found on current GM vehicles. It is used for the coolant temperature as well on LS engines. It uses a M12x1.5 thread pitch (straight thread). Trying to find a weld in bung is very difficult in this size so I bought a tap and made my own. It's very important to have the hole and threads tapped/drilled at a perfect 90 degree angle as this is not a tapered pipe thread. The crush washer provides the seal. You might want to make a couple of these. I plan to put one in my LS9 supercharger coolant tank as well in case I want to monitor the coolant temps. (shown in the third picture). Keeping an eye on the IAT temps is important with boosted motors.
