I think this is what your looking for. As far as diameter, Im not sure. Find out what -AN size the turbo oil feed hole is on the turbo, or ask around...

Here is where I tapped mine, then installed a brass plug untill I'm ready for the turbo. There is a circular depression at this spot, perfect for the tap.
