I have been reading that site and others but can't seem to find the info I'm looking for. I'm trying to find a good balance between HP and MPG. Since I drive over 50miles per day for work, I need to get the MPG, but I also struggle on the hills with the 2.6 setup, so I'm wanting more power. If I look at taking a straight up 2.4L swap, do people notice a decent difference? I found a MS 2.4L, but that is the 7bolt. I think I understand that I would also need the flex plate, but what about the torque converter? will it bolt up to my AT? In my mind, I think I'm looking for something in the 150hp range, but I just don't know. I know turbo would be fun, but not sure if I need it. I'm just looking for the most cost effective swap that is not a 2.6L
