Is anybody using some kind of aftermarket oil feed line for K03/K04 turbo? Something like a braided line with some adapters to fit turbo / oil cooler fittings and keep the same flow/pressure as OEM. Thanks

i think the OEM piece is fine. no reason to upgrade for a K04, but most BT kits supply custom lines.

but more along the lines of swapping for a GT3071R.
Anyway, the following information can be useful to you.
The stock oil line attaches right here at the oil cooler.

and enters the turbo here.

You can buy an adapter for the oil cooler that will have a -4AN nipple on the other side here.

You can build a feed line with a -4AN braided stainless steel hose and hose ends available here.

Now, I'm not sure about the connection at the turbo because I researched for a GT series turbo which requires a restrictor, you could contact 034 and ask them what you need to feed into a K03, they'll know.
Good luck.
I also researched the oil drain, water in/out lines if you need more info.

OEM feed line is fine for a K04 setup.

They are braided lines. I got new ones from ECS before putting in the K04. Since the K03 had 93K miles on it, I didn't want to risk any potential sludge or buildup damaging the new turbo by using the old lines. May not be necessary, but was just an added precaution for me.<ul><li><a href="http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi?make=Audi&amp;engine=1.8T&amp;mod el=B6%20A4&amp;submodel=Quattro&amp;category=Engin e&amp;subcategory=Turbo">Oil Feed and Return Lines (at the bottom of the page)</a></li></ul>
