why would you really need more hp/torque if the engine you have is quite capable of going up and down those hills?

honestly i think your doing this whole ordeal for the wrong reasons....
why not just keep your GREAT gas milage instead of swapping or turbo? do yourself a favor, make your car just a cruising car, if another honda passes that you know has a swap, just smile at them, knowing that they probably dont have A/C cuz they pulled it
well what ever you do goodluck to ya, read up on more things, there is tons of threads on this stuff in this site, just search for it, swapping or turbo no matter what you do will cost you. fast and cheap dont usually go side by side, and fast and realiable diffinately isnt cheap
