Style chooser

hi.. i've been thinking abt changing my standard wira 1.5 engine with a.. say 4g63.. basically.. coz i want better pickup and horsepower..

but.. my friends are telling me that i should just stick to my standard engine.. they say tht if i change the engine, the price of the car will depreciate more compared to if i stick with the standard spec.. is this true?

obviously, changing the engine would require a lot of money (the engine, wiring, workmanship etc).. so, my friends said i should...
