I believe the 4 cyl only has about a 1,000 lb towing capacity. Of course, this will be greatly reduced depending on the size tires you're running. It will do fine on flat pavement but good luck going up hill.
The four banger with an automatic has a 1200 lb. tow rating with a 2000 lb. tow rating with a manual transmission. I think Chris's 1000 lb. suggestion is probably more realistic and is about all I'd want to tow with the four-banger though.
