35 micron seems to have good flow and catches small enough debris. I was able to blow out (by mouth) the oil from inside the filter. So the oil pressure should have no problem feeding oil to the turbo. Take a look at the size of the oil feed hole on the turbo. Mine is like a tiny pin head. The turbo need every little oil to lubricate the bearings. There is no reason to run a -6 AN feed line.
