Its really not "as" bad as these guys say, I'd consider it better than the talon really. Mostly because once you're done working with all the main maintenance items, you can actually drive it awhile before it breaks again. Seriously though, with some TLC and some smart, well thought out mods, they're pretty capable cars but if you're looking for a lot of HP, its better to swap it. You'd be wasting a lot of money on it, when the same amount on money on an EJ would get a lot more power, and it would be reliable.
Also, it needs some sort of programmable EMS before you even think about touching the boost. I know your talon can take like 40lbs before you need even a SAFC, the RX is not that boost friendly.
