For literally any other turbo it's a guess,

so if you think you're going to put a 10AN drain on a Borg Warner and have zero issues you're mistaken.

Here is basically what I run for my drain....

I dremeled out my stock drain hole to the same size as the pan adaptor.

that is a good holset drain with VERY minimal pan modding.

I run a cut 2g drain tube (17 bucks) a piece of 3/4 hose about 6" long and a 3/4 threaded t3 barb fitting with the ID drilled out a bit.

total cost me about 30 bucks to put everything together and a little patience so as not to crush the 2g drain tube since it's thin metal. once it seals properly on removal I just undo the upper hose clamp and separate the barb fitting from the hose and lift up and out.

My holset removal takes about 45 minutes now start to finish. given a choice I'd never run anything else again just for the ease of swapping out.

EFR series is ball bearing....I assumed we were talking journal bearing here only. If you want to get technical an 8AN drain is probably fine on a GT Garrett turbo too due to the tiny amount of oil they pass but there's no reason to ever go smaller than 10AN and risk damaging a $2000+ turbo since so much hardware is already available.

A couple good videos to watch on the topic of undersized or poorly-run drains:
