S4 turbo drain question

3rd and final 7 · 03-30-2009, 08:06 PM

Im starting a turbo add on my Fb (which has a 88 NA), so question is what is the smallest size that i can use for my oil drain. im going to tap my front oil cover with a 3/8 NTP and use 8AN lines is all this too small?

Also what is the best size to run for oil feed 3 or 4AN i been reading both and do i need a restrictor?

Thank You for your time

Basically, you should measure the ID of the stock hose (inlet and outlet) and make sure that yours is the same (or close). I can get you dimensions on stock lines tomorrow (I don't want to go down to the garage right now).

I'd be scared with the -8.
I use -10 minimum with -12 recommended.
