Im not sure about the HP rating on the 4 Cyl. But I would steer clear of it unless you plan to turbo charge it. The the 2.6 4 cyl is Carbureted, which works well when the carb is in good working order. In my experience the Fuel injected V6 is smoother and easier to keep it running right. The carb has a million vacuum lines that i would not want to deal with. But thats just me...

From what I understand your looking for a 4 door which is only available with the 6 cyl anyway...
