1: Yes the thin oil line that goes around the back of the engine is the
feed line, Motion dynamics has one for like 49$ its a aeroquip line. or you
could make one.
2: I believe what he's talking about is that turbonetics sells a fitting
that bolts to the oil drain hole of any T series turbocharger. This allows
you to custom make you oil drain line and if it breaks, replace the line
not the fittings.

Hey spoier- since you've got the engine out already, could you check and
see what size the fitting is for the return line on the block (the fitting
below the exhaust manifold)? Also the length of the return hose.


 On the return line, I recommend using either higher temp silicon hose or
 higher temp teflon hose. Its pretty hot at the turbo. Alternatively, you
 can use the Turbonetics threaded return fitting (see the Turbonetics
 website or a print catalog) and then thread in a hardware store extension
 nipple (say, 1/2 pipe thread by 2 or 3 inches long) to get you a few
 inches from the heat. Depending on your manifold and turbo, you may have
 to use angled fittings and multiple smaller nipples, because the return
 line needs to slope downwards to the return hole.

 Beware that 1/2 inch hardware store hose barb fittings may not work
 perfectly with -8 braided hose. Ideally, you would invest in proper AN
 adapter fittings from the pipe thread Turbonetics fitting or from your
 extensions from that fitting.

 The return line should be twice the size of the feed line. Feed line can
 be -3 or -4. The longer it is, the bigger I would use. The hole in the
 turbo is only 1/8 NPT, so it is pretty small. You don't need to hook up a
 -6 line to it; it probably will not hurt, but it won't help, either. 1/8
 NPT is about 0.125. -4 is nearly twice that. Teflon -4 is a little less
 than the normal rubber -4 (about 10% less diameter). I went with a teflon
 -4 feed line. You can buy teflon -3 and -4 line preassembled in various
 lengths, but you will probably need some AN to pipe thread adapter
 fittings to get to the block and to the turbo.

just got one of these made. I used the Turbonetics return adaptor. Both
the adaptor and the block are 1/2" pipe thread. I used SS braided
Teflon(about 6 or 7" long) with 1/2" pipe thread comp. fittings on each
end. I had to use a 45 degree adaptor into the block. It's like our stock
adaptor,but the side the hose goes into has a 1/2" pipe thread comp.
fitting with a nut. Other wise you couldn't get the hose on. Also using an
E6 I couldn't see threading the hose directly into the bolck as it would
kink or end up exessively long.
Cost- Turbo adaptor $13.00
SS Teflon hose$16.00
No more oil on my starter $priceless

I also had them make a oil feed line. 36" long with 1/4" brake line
fittings. Total $22.00
