Thread size needed for Precision water cooled turbo?

[TR Custom Parts]

What size is the thread for the water cooled Precision turbo outlets? Going to make up my own kit for it. Also, the oil feed line where it connects to the turbo, they aren't drilled for for use with a flange with built in -4 connector are they?? Have something like that on my TA49 but from pics of these turbos they aren't drilled.
