if i want to transplant my 1.3 engine into bigger size engine.....what the best choices??what engine that give best between fuel consumption and performance......not for racing ok, just for daily used.....FYI i use this car to work everyday (189km a day) and it consume rm20 a day (coz i keep refueling everyday) with driving around 80-90kmh.....it is good or not???

now i'm thinking to swap the engine coz i feel it really lousy...no pickup and also consume too much fuel when i speed up around 110-120kmh..rm20 not enough per day.....

i hope u all can give comment and also suggestion for my problem......if transplant is the best solution, hope u all can estimate the cost that i have to pay, also the best shop to go (in pahang if possible)
