a couple newbie turbo questions
id like to install a blow through turbo setup on my 12A using an s4 or s5 turbo and im just doing a little homework. ive read that the fuel lines need to be replaced with bigger ones, does this mean the rubber ones or the hardlines under the car? also why should the oil return line for the turbo be bigger than the feed line? thanks in advance.

That's a good question. I am putting a turbo motor into my car now and not thought about it.
And if you need to increase the line size would you need to weld in bigger intake tubes in the gas tank as well?

There is no need to replace the stock hardlines with bigger ones (AJC13B made over 500rwhp on the stock ones).
You can never have a big enough oil return line. If the line is to small it will restricts the flow and make oil seep past the seals in your turbo (it will smoke). A -3 or -4 oil feed and a -10 return works nice.

yeah, return is low to non-pressure, so it has to be larger than the feed.... otherwise, like frode said, you'll get oil weep past the seals, and it will burn off in your hot exhaust manifold and make it look like your car has a mAdD oIL lEaK y0!1! which isn't very cool....
