I have a 2000 Chevy Tracker 4x4, independent front suspension, 2 doors, 1.6 liter engine... Is just the engine made by suzuki, or the entire thing? What Suzuki model is this equivalent to; a 2000 Vitara? I'd like to learn about what upgrades/replacement parts are available. (I may need to replace front CV's, wheel bearings, maybe even diff) Thanks
