Subject:      Re: Subigon oil sump

Shortened oil pans are the state of the art for Subie conversions, and Subie powered sandrails. They are not an issue. They are used by the thousands. Shortened is a subjective term. Because of its engine configuration, Subaru puts a incredibly deep oil pan on their engines. 7 inches deep. They do it because they can. Deep is good. Their engines are shallow vertically so why not? Most commercially available shortened Subie pans are 4 inches deep. Racing sandrails use the same thing, putting out 300-1000 hp and going straight up and down without oil pressure issues. If they needed a dry sump, the racers would be using them. 4 inches is deeper than most modern, stock, 4 cylinder engines. A great comparison - take a ruler to the pan on your WBXer. Take away the cooling fins, and it is 1 3/8 inches deep. 4 inches is still very conservative.
