I do just fine with my setup. I have a K & N style filter mounted on a straight intake tube from the turbo inlet. The hose from the valve cover runs directly to this tube and all the gases are inhaled by the turbo and then burnt.
The car doesn't smoke much at all and I use less than a 1/2 quart between changes.
