turbo
If the oil feed (pressure) port has threads to not only install a fitting but also threads inside the hole where oil goes through, then it is ball bearing. It's kinda hard to explain, but if you take a close-up detailed pic of the oil feed port, I can tell you if it's BB or not. The reason for the fine threads inside the oil feed hole is so you can install a small bolt, and remove that pin using a slide hammer. This is how you disassemble BB turbos without damaging the bearings. We do it everyday... It's called the location pin. It pins the outer race or outer shell of the ball bearing unit in place. Let me know if that makes sense.
