The D14A3 and D14A4 engines are identical, the difference is found in the valves, this is the reason the D14A4 produces 15 hp more then the D14A3 (Author is wrong, actually there is no difference between d14a3 and d14a4 in mechanicall parts, there is only one small gasket under trottle body in d14a3.)
Asi que no lo dejan muy claro... uno dice que en las valvulas, y otro que solo es en la mariposa...
