I bought a 97 City EXi last year 'coz my other car is a gas-guzzler. Heto ang walang-kamatayang tanong: what is the real engine displacement of the 97 City EXi?

FYI: my mechanic told me it's a 1300 kasi yung engine # daw starts with PHZ13... a Honda dealer told me it's a 1500... other threads are confusing, hindi consistent ang mga sagot.
my City's kpl is only 9-10, it has PS, front power windows, all-door power locks.

In addition, I can spot some 97 City with 1.5EXi badge on their rears. Mine is only EXi kasi na-repaint na kaya no way to determine if orig yung badge. The former owner is already in the US (no contact details).

Thanks for your help...
