What are the specs?

 

Diameter, compression, weight, wrist pin size, number of rings. Can we do a comparison of all of these with all the available subaru engine types?

As I recall the diameter is the same for all - EA82 pistons had compression ratios 9.0:1 (carb/early MPFI N/A), 9.5:1 (SPFI/late MPFI N/A), and for turbos, 7.7:1

I think the EA81 had 8.7:1 compression

Don't know about EA71

All are 3-ring slipper type - and I think all are interchangeable
