S4 T2 into SA turbo oil drain line ?
 

Wishing I had tapped the front cover for the drain now that im dealing with finding the right fittings
I used a 10 an bulkhead fitting at the oil pan instead and the original drain line looks closer to 12 an so my question is the 10 an too small for the stock turbo? Really not looking forward to removing the oil pan again.....the original line has stainless flex under the stainless braid so im tempted to flare a gas flex. Or ..i know it sounds redic but it was ok for Mazda factory there is very little room for hose and fittings on this short piece

-10 will be fine. I always use -10 for oil drain.

If you are talking the stock turbo, yeah, there isn't much room. With a T4 AN drain flange and a 45 degree you can make it work but the line won't really be removable with the turbo on the car unless you remove the compressor cover. Often I have welded a piece of bent tube to the drain flange then welded an AN flare on that once clear of the turbo. Or you can braze a flare/NPT onto the cutoff stock line.
