EFI can do wonders for some "unefficient" engines, yet I don't know if something like a Fueltech would be legal there even for a car originally fitted with a carburettor.

Not sure if an O2 sensor is used, but in Argentina some folks go as far as adapting carburettors to vehicles fitted with EFI instead of fixing the EFI when it goes bad.
