So I have my 1N Engine overhauled, It doesn't have the turbo with it or was removed before I bought this car. After running and first oil change, this car (Hyundai Excel 1993 Base grade) is now giving me around 28-30Km in long and around 25-26Km in Local. Although I am happy with it Alhamdolillah but just for the sake of argument, how much fuel efficiency will be effected If i get the engine turbo charged.
