Caboobaroo Posted May 2, 2015 Share Posted May 2, 2015 Looks about right. I would say that the pistons in the EA are JDM EJ25D pistons from how deep the valve reliefs are cut. That is a ER27 as well, and turbo pistons. Quote Link to comment Share on other sites More sharing options...
skishop69 Posted May 3, 2015 Share Posted May 3, 2015 Any idea what the gain would be? You get 9.5:1 with the EA82 SPFI pistons. Quote Link to comment Share on other sites More sharing options...
jono Posted May 4, 2015 Author Share Posted May 4, 2015 builder may have been using EJ stufffor later being better design and strength. I think it was high comp turbed EA82 and had problems . Quote Link to comment Share on other sites More sharing options...
skishop69 Posted May 4, 2015 Share Posted May 4, 2015 I figured better design and obviously easier to get. I was just curious as to what the comp ratio is. Quote Link to comment Share on other sites More sharing options...
jono Posted May 4, 2015 Author Share Posted May 4, 2015 think I saw 9.5 Quote Link to comment Share on other sites More sharing options...
skishop69 Posted May 5, 2015 Share Posted May 5, 2015 Ok, so the same ratio with better pistons. So was this a direct fir or were modifications required? Quote Link to comment Share on other sites More sharing options...
