Technical punto 1.8 hgt piston size

[jdman]

Hi I have a puto arbarth 1.8 race car but it lost compression on number 2 cylinder. when i opened it up piston had broke but i suspect there may be oversized pistons in it but not sure. Does anyone know the size of the standard piston for the 1.8 the ones in the car are 82.3mm
