Audi S6 Turbo Line Replacement

Audi S6 Turbo Line Replacement

The old turbo lines were crappy. Not all of them, mind you. I did replace most of them in the past, but a few of the repairs were not ideal due to me not having the proper braided line cutting shears. Now I have them!

The main problem was the coolant drain line. I made a line that went over to the bung on a freeze plug with a hose clamp securing it. This is a bad idea for many reasons. It leaked, it was ugly, it frayed, it looked bad, and it leaked. I redid this with an AN fitting and a custom freeze plug with a -6 AN fitting from Ultra Performance. Mad!

You can see it is still slightly frayed, but you're going to get that no matter what with this type of nylon braided cable. It will be covered with said -6 AN fitting in the future, regardless. Wait a second, I forgot to sandblast and Cerakote that banjo fitting!

You may be wondering why I went with a 90 degree fitting and the answer is simple, really. It has to be. On later generation Borg Warner turbos the flanges are all drilled for NPT or AN style fittings. On this old generation Garrett turbo, however, the flanges are single bolt banjo fittings. I am now realizing that I can just get a threaded Vibrant AN fitting. I am now ordering these parts.
