Default Turbo oil drain size

Hey guys,

Did a quick search and couldn't find the spec.

I just pulled my SR20 T25 to put in the T28 and didn't realize the oil drain from the turbo on the T28 is smaller than the one from the T25. Is there a common standard size that I need to ask for? Will the brass fitting that goes into the adapter plate be a different thread size too? Or should I just drill/slot out the two holes for the bolts that hold the flange to the turbo?

I just went to Mopac and they have oil drain flanges for turbos and they found the right one.
