Mazda 3 comes with 14:1 (13:1 in U.S. for cheap gas from Wal-Mart) DI engines. For just DI 12.5:1 in this car is really low. Even lower if it gets tuned for E85. E85 tune with supercharger will be perfect! Even just normal E85 tune with injectors from 3.5L V6 will do pretty well. Not sure about the fuel pump.
