I have to buy some new ones, and the return line is $85 from mazdaformance, so ack. if i can get a nice reuseable SS/Earls fittings line made for the same, I don't see a reason not to.
I remember seeing a thread on someone who made on efor stock turbo, but searched and couldnt find it.
What is needed to make the feed/return lines
and would making ss/earls fitting lines instead of stock be detrimental at all? I don't want to downgrade by just being ignorant and figuring that its better.

Let me try to find those Aluminum threaded oil flanges

It's a 10am return line for stock.

You can buy the adapter plates for the turbo and our housing from www.turbosdirect.com over here in Peoria.

I think their the T3/4 flanges.

I recommend a 45 degree angle instead of the 90 I used. It shoudl hopefully make it a better drain than what I use.

On second thought use the 90 still. I think due to the stiffness of the tube you won't get a good angle and it might pool.

I bought my AN/SS stuff from Lopers. The end pieces cost me around $5-7 each.

ive decided to leave the oil feed line alone, and the coolant lines too since theyre all metal, but the s4 to s5 differ. so im still debating.
you ever fix your oil pooling/smoking problem with your return line?
