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.
