Does a motor from 2000 2.4 cavalier fit in 1995 2.3 cavalier?
No, a 2000 2.4L Cavalier engine will not directly fit into a 1995 2.3L Cavalier. While both are Cavaliers, the engine bays and mounting points are different enough to prevent a straightforward swap. The 2.4L is a significantly larger engine. You'd need extensive modifications, likely including new motor mounts, potentially different wiring harnesses, and possibly even modifications to the firewall or other body components, making it a very complex and unlikely project.
