After a few beers and nigh time I I <3 Bananased up the turbo drain on my na to turbo conversion, I now need to modify the drain so it stops leaking oil everywhere, I want to tap the hole and screw in a barb fitting, does anyone know what size tap and fitting I will need for the big oil drain hole in the sump?

since you'd have drilled the hole yourself (there wasn't one to start with and there now is) then just use the size drill you used to check the tap size you need to suit it. :idunno:

well, get some calipers, measure it, use a tap to suit. Or get the fitting you want to use and drill+tap to suit it.

 

That's how I'd approach it, because the N/A doesn't have a hole, so if you had a hole there, you'd have other problems.

 

you can always tap the bolt holes for the standard oil return line and get it to hold a lot tighter (and not leak) with some loctite and a gasket.
