thats not what I meant,I meant if its good enough for oil feed it should be good for turbo, bigger size would be stronger then the have them in all sizes.

the reason u use SS is because it can deal with the crazy vibrations the motor makes, copper on the other hand doesnt do to well unless its support and braced everywhere.

is SS really that expensive?

i dont think so

yes I pay $80 for my feed line just the feed line, but I fucked, cause I'm a mechanic in the army and I can get these free just risky, I sold a couple on ebay for $20 for 3 3-1/2 ft pieces with fittings on them, I can supply some but, the source is not reliable.

stainless steal will last longer

Every factory turbo I have ever seen has had hard line for oil feed, usually steel, like brake line, sometimes stainless, usually like 5/16 ID. I do a lot of work on BIG turbo diesel trucks, like Ford L7000s and Isuzu NPR/NRRs, they all run hard steel line with no problems, and they vibrate alot. Copper should be fine, it will hold like 200 PSI.
