Engine will be 1108cc,
Subaru used the same ECVT system on one of the Justy's. Gearboxes were manufactured by Fuji Heavy Industries ( Subaru ) for Fiat.
Clutch is not torque converter as such, it is an electro magnetic " powder " clutch.
Know nothing of the spares situation there in Japan but normally order spares using the VIN on the plate inside the wing ( as previously stated )
This is the number starting ZFA141AOO ********
Good luck.
