I have vorshlag plates and M3 arms and I'm only at -3.0deg up front. I started working on a custom plate design to get more but haven't finished it yet.
Are you revving it out to 7500rpm? I'm guessing the N54 IM isn't the culprit of the oil consumption but rather winding it out further. Still, 2 qts seems like a lot, just all the extra crankcase pressure at that rpm pushing oil past seals?
