Turbo oil pipe replacement

:
2008 Mazda CX-7 iSport
Had to replace the turbocharger on my 2008 CX 7 due to a busted oil feed pipe. Has anyone used an aftermarket braided line instead of using a oem pipe? If so what size banjo fitting should I be looking for?
 
Sorry I don't know what size banjo it is but I'm looking for info on the turbo swap. My mom has an 08 and it sounds like this is happening to hers. Problem is, I'm in Houston and she's in Charlottesville. Trying to figure out how hard it is to get to before I go up there to fix it. Her Mechanic looked at it and doesn't want to do it.
