Default Alternator upgrade from 90A to 120A

I intend to upgrade OE,MY99 alternator of 90A to MY2002 type alternator of 120A.

Though the potential difference is the same i.e 12V but the amperes is 120A instead of 90A.

Would this be OK for the electrical system?

Default should be fine.....>>

i would be worried more about the electrical connections and potential re-wiring.

A higher amp alternator allows more accessories and all, but i would probably also add a second fuse block to handle the additional items (if you add any).....fwiw
