first of all, this aint sugar that its price will rise with time, and even if it will, they wont be getting so much high. secondly, what do u mean by engine bara hai? :S liana comes in two variants as mentioned by you, if considering the 1600cc one and comparing it with the d16 civic, both of their displacement's are same so there is no point in saying k engine bara hai. both the cars have the same displacement. and thirdly, can you please mention why do we have to spend more on liana? ok lets separate the 24,000PKR for the nitrous oxide kit, where do we have to invest the rest 76,000PKR? intake, exhaust, plugs, groundwires. how much would all of that cost? 76k? :S
