Diameter of oil return and compressor outlet?
 

I'm starting into the prep work for a Greddy install, and I need to verify a few things.

First, the manual which is posted in the Greddy Archives section indicates the supplied oil return hose as 19mm, which is 3/4". Is this correct with regard to the oil outlet of the turbo? I was expecting a 5/8" line, based on reading up on the "other" 1.6 turbo kit. I'm thinking about tapping the pan while I've got the steering rack out of the car, and I need to know what size fitting to install.

Secondly, anybody happen to know the outside diameter of the compressor outlet? Can't find any data on this one at all.

2 inches on the O.D. of the compressor outlet if I remember correctly.

Pretty sure 19mm is the size of the drain, it's a fatty.
