Ross Posted June 25, 2005 Share Posted June 25, 2005 Got a parts motor for the ea81t today, noticed that the pistons are slightly different...(aside from the dents in one from a broken valve.....) Anyone know anything about the difference? Quote Link to comment Share on other sites More sharing options...
MilesFox Posted June 25, 2005 Share Posted June 25, 2005 the one on the right looks like an ea82 piston, if the other one is originally ea81. the one on the right looks like ea82's that i know of Quote Link to comment Share on other sites More sharing options...

THe ones on the right are quite new i think, they probably supercede the ea81t ones... Cheers Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted June 25, 2005 Share Posted June 25, 2005 The non-turbo pistons (EA81) are 8.7:1, and the turbo ones are 7.7:1. The turbo pistons would have a larger dish. Quote Link to comment Share on other sites More sharing options...
Ross Posted June 25, 2005 Author Share Posted June 25, 2005 Both are turbo pistons - non turbo ones are flat. Quote Link to comment Share on other sites More sharing options...
Ross Posted July 2, 2005 Author Share Posted July 2, 2005 Got those pistons out, seems they are a non subaru part. Here are some pics of them, notice the shorter skirts on them compared with my other ones. Anyone know anything about these? -They look like they will give a lower comp ratio than my original ones..... ???? Quote Link to comment Share on other sites More sharing options...
