Do you happen to have any sources or info on the other species? Personally I think it's kind of hard to mistake turbo fluctuosa after you see one and I'm not familiar with many other species that get as big (that are sold in the hobby).
Check Turbo funiculosus (lives in pacific baja).
Turbo fluctuosa also has populations living in both sea of cortez and pacific baja and coast of California. Those two waters are considerably different in terms of temperature.
