The pan will work in some cases, but there are a huge percentage of turbo cars that have smoking issues on de-acceleration. I know I don't want that hassle! This is due to the oil being hydro locked in the drain line when the oil plugs the line from forward g-force. I use the timing cover and have had no issues draining the twins stopping from 150 mph as fast as possible.
