the title in link may be a bum steer as we see pics of what look like EA turbo pistons in a flat six - ER27 ? but is deffo a flat four EA in first pics

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.

Any idea what the gain would be? You get 9.5:1 with the EA82 SPFI pistons.

builder may have been using EJ stufffor later being better design and strength. I think it was high comp turbed EA82 and had problems .

I figured better design and obviously easier to get. I was just curious as to what the comp ratio is.

think I saw 9.5

Ok, so the same ratio with better pistons. So was this a direct fir or were modifications required?
