for the 98 year, there is the 2.2L and the 2.4L which you have. You have to find a motor from a 96-98 Cavalier Z24, Sunfire GT, Grand Am, or a Malibu. They all share the 2.4, beware though, get one wiht the LOWEST KMs you can find....I have blown 4 of the 2.4's.....so don't race it around, drive it nicely, and CHECK THE OIL OFTEN, they burn it.......its a quiet running engine if kept in good order, if not, you'll see what happens....it's not pretty. Hope this helps your search!
