I think the drain location in this particular case is a good, better, best situation. With the right turbo big enough drain line and X number of other factors going right plugging a tube into the factory drain plug location may be good enough. Mounting it higher up with a more direct gravity feed like in the Greddy pan is certainly a better idea with a few clear advantages, but the best way to go is above the oil line, but not so high that you lose optimal drainage to shallow angle on the drain tube, or **** getting in the way of the oil on the way in(IE if you crack open an SR20DET the oil feeds back in pretty close to the oil level to avoid draining directly onto the spinning crank, also to maintain a steep drain angle from the turbo that is spaced pretty far away from the block).

Also something to consider before condemning any problems with Greddy's pan is that when the engine is operating, especially under load or high RPMs, a large majority of that oil will be filling oil passages, coating components, and dispersed in the oil cloud of the crank case. So even though the oil comes up that high on the dipstick under operation there is probably some room to play with.
