I know it has a vvt-i engine but is that the exact engine or is there another thing? Also is there a site where I can find information by checking the VIN number?

best thing to do is look under your hood and see what the top of your engine block says then go on goodle and type that in along with your year and model of your car and boom you got info. also by doing that you will get a lot of forms that people talk about those cars on.
