kingbobdole Posted January 3, 2005 Share Posted January 3, 2005 I was digging through some files about my car and found this: http://www.ultimatesubaru.org/80s/specs/general/1987glwa.html Under the section on engine specs it says: Engine Specifications: EA-82 Displacement: 1781cc/109 cu in. Aspiration: 2-bbl Carburetor Compression Ratio: 9.5:1 Horsepower: 84 at 5200 RPM Torque: 101 at 3200 RPM Spark Plug Type: BPR6ES-11 Plug Gap: .039 - .043 inches I thought that the carbbed block has like 8.something to one compression. Am I crazy or the site? Link to comment Share on other sites More sharing options...
