There two major differances in the Tracker/Sidekick and the Samurai. After the first couple of years, the Track/Kick came with a big block motor, 1.6. Four door models had a dual overhead cam 1.6 for even more hp. These motors can be swapped into a Samurai easily. That was the good, the bad is the Track/Kicks all have IFS. While it rides good, solid axles are much better for off road. JC
