WRX Turbo Replacement - Do I need to replace the oil line?
I'll be swapping my turbo out this weekend and am wondering what others have done with the turbo oil supply line.
Vargas Turbo recommended that the turbo oil supply line should be replaced before installing the new turbo, but I've never read anything about replacing this line. I figure it can't hurt to at least clean it, but should I really replace it?
I found a couple vendors who sell braided replacement lines, but nothing stating that the line should actually be replaced when installing a new or rebuilt turbo.
I searched both scooby mods and nasioc already, all I can find is info on people breaking this line, and how its a huge pain in the *** to replace this line.
Please share your thoughts and experiences with me on this subject if you have a moment.

Replacing the line(s) assures that the turbo gets plenty of fresh oil & can drain the whipped up oil completely.
I'd clean the supply line, the banjo bolt (especially the pin hole & get new copper washers!!), and replace the rubber drain hose.
That is all.

When I did my VF39 swap, I found that the stock TD04 supply line had to be bent just a little in order to line up on the new turbo.
I would like to switch to a braided line, but Im wondering if the turbo would be getting too much oil(?) or if it would drop the oil pressure since the hole in the banjo is so small
Replace the crush washers, as they are only good for one use, and when you put the turbo back on make sure the oil return is indeed hooked all the way up. Its a pain in the ***.

I know that the mods are trying to keep the forum organized, but we all know that the technical portion of the forum does not get a lot of traffic. Take for instance my thread about Wilwoods in the brake section. I didn't get a response to for a week. Maybe we should consider leaving this thread in the section it originated and archive the thread after it idles.

82K miles, over a dozen auto crosses in the last year, and some hard mountain driving(dirty engine bay).
I figured this would get moved, I really don't mind though. I mainly just wanted to catch the eyes of bay area folks since many have done turbo swaps. I am open to getting a braided line as long as it doesn't cost too much. Not sure if it's really worth getting since I am just putting another stock turbo in.
I wonder if the dealerships have these parts in stock :crosses fingers:

um the banjo bolt you can get from the dealer, the copper washers you can probably call up McMaster Carr, though I used these copper brake washer thingys I found at Kragen.
Don't worry too much about reusing the bolt unless you cross thread it. I kinda cross threaded mine and ended up grinding off a few threads then the bolt fit again.
Don't over tighten the bolt. Just tighten it a bit and it'll depress into the copper washers. Start the car, if oil leaks don't panic, just shut off car and tighten it some more.

Replacing the line makes install a bit easier because bending the line around is annoying especially for bigger turbos, especially trying to align the bolt with the hole.
You can get them for like $80 at FP I think.
IMHO, don't worry about it unless you're going to a much bigger turbo. Even then, whatever.

I couldn't find part numbers on Nasioc either. Thankfully though Subaru of Santa Cruz does have the washers I need, as well as the oil return hose. 
I'll post part numbers once I pick them up.
