get a -3an NOS line about 3-4 ft should do the trick. and you dont even have to assemble it.

I did my research on here and elsewhere, it seems 3an is standard for these types of setups. A turbo does not really need a huge ammount of oil and the extra pressure is not going to help your seals.
You could get 4an and use a restrictor to limit the pressure, Then you could adjust it to your liking. Some VW guys do this

You need to know what size hose the turbo manufacturer requires. Typically Garrett outline drawings specify a size that would be equivalent to a -6 hose. The concern of excess oil supply flooding the shaft seals is not warranted, especially if the drain is properly designed. If the turbo needs to be restricted it will have the proper restriction built into it's oil passages. The reason to specify a large enough hose for the oil inlet is to ensure that there is always sufficient pressure at the turbo oil inlet. A long small hose can have quite a bit of pressure drop. A -3 or -4 hose is often easier to plumb but if the turbo is starved for oil you will be in trouble.
