I know on the Greddy kits that you can install that hose preturbo and it will suck the oil into the compressor blades and into the intercooler piping. I have no idea if it is the same with a drag kit since they may not even use a pipe but just a filter on the compressor housing.

If you can find a rebuild kit for that turbo, it isn't that hard to pull it apart and replace the seals yourself.
