MitsuStyle - View Single Post - Difference Between Helical Gears And Straight Cut

Are you talking about a DSM? If so, anything newer than 90 or 91 (somewhere in there?) I believe should have helical oil pump gears. The helical style does make less noise especially on those cold winter mornings when you start your car. As far as lowering oil pressure, I wouldn't think it would make that huge of a difference-at least in our cars.
