i have an s5 TII and i'm wanting to make a t4 oil feed and drain out of stainless line and earls fittings. i'm sure someone in here has done this, i just really dont know where to start as far as the flanges, what size lines (-4 for the feed and -8 for the drain?) and what fittings to buy... can anyone offer any input or possibly a parts list?

 

-3 and -10.

Fittings depend on the turbo, but you should be able to find most all you need at www.atpturbo.com.

i.e. for the return line (bottom of turbo and engine)

 

There have been a few threads in the past that list the part numbers and everything that you will need. I know you dont wanna hear this but search and you will find them.

 

3 or 4AN should work for the feed.

an 8AN will NOT be large enough for the drain.

the turbo "whips" the oil into a foam. the larger/steeper the drain the better. i have a 10AN drain and 4AN feed on my FC and get a tiny bit of smoke on occasion. if you can fit a 12AN use it. 3/10AN setup might be perfect

i bought (2) areoquip steel 1/2NPT to 10AN fitting (~$8ea) and cut off the NPT side and then welded them to the flanges that are factory on the FC oil drain tube extention. this flange size is right for the T4 drain.

good luck

PM for more help if interested

I use 3/10 with a .125" restrictor, no smoke at 80psi+
