ktperry Posted June 2, 2005 Share Posted June 2, 2005 Does the EA81T use the same pistons as the EA81? I know some turbo cars use low compression pistons. Also does anyone know what the compression should be in an EA81T. Kevin 1983 Subaru Brat Turbo Quote Link to comment Share on other sites More sharing options...

carfreak85 Posted June 2, 2005 Share Posted June 2, 2005 If you mean stastic compression, then the EA81T has 7.7:1 while the N/A Ea81 has 8.7:1. Quote Link to comment Share on other sites More sharing options...
