Help identifying pistons

Found these in a 1.7 "EC" engine and would like to buy new rings and possibly barrels.
Any help would be appreciated.

EC would be a 1.8 motor, not 1.7. Those appear to be around 94mm in diameter; the stock 1.8 pistons should be 93mm, which is close enough from this photo.

Stock 2.0 pistons would be 94mm in diameter, but they don't fit on the 1.8's crank and rods.

A popular aftermarket "big bore" size is 96mm; there are versions of that kit for the 1.7, the 1.8, and the 2.0 motors.

The arrow visible in the first photo would typically point toward the flywheel.
