I am wondering what my options are for increasing the horsepower. 138hp stock just isn't cutting it for me. It's a vehicle I will be using for a while and I have already put money into. I am open to doing an engine swap, if it doesn't end up costing more than the price of the car. So is there a cheaper option to give this little car a nice boost. I am looking for 160-180hp range really. I haven't hardly any custom elantras and it's a shame. This car is very nice it just doesn't have many options for any custom opportunities .
