re the evaporator.. not sure about the brand, but it looks like those hanging type evaporators but without the grill, instead 4 big holes to place the ducting hoses to connect to the dashboard grille, so you retain the stock look but now have a better evaporator/blower unit

yes, gusto ko nga sana ng 240d para more power.. regarding the 300d, oo naman, pero baka laklak na din sa krudo hehe.
