* Different engine mounts: The engine mounts and their locations on the 1989 and 1992 engines and chassis are unlikely to be compatible. You'll need custom mounts or significant modification.
* Wiring harness and computer: The 1989 engine's wiring harness and computer are not compatible with the 1992 Camaro's system. You'll likely need to extensively rewire or use a standalone engine management system, which is a complex and potentially costly undertaking.
* Transmission: The transmission compatibility depends on the specific transmission used in the donor 1989 2.8L. You might need to adapt the transmission or find a compatible one.
* Exhaust system: The exhaust system will need modification or replacement to fit the 1989 engine.
* Other potential issues: You might run into problems with the accessories (alternator, power steering pump, etc.) and their mounting locations.
In short, while it's *theoretically* possible, the amount of fabrication, rewiring, and custom parts required makes it a very challenging and expensive project, far beyond a simple swap. It would be far easier and cheaper to find a replacement 1992 2.8L engine or consider a different engine altogether.
