I have a 2002 cavalier 2.2L vin 4 not ecotech. Was wondering if its possible to do a conversion from rear drums to rear disc brakes.

 

Anything is possible.

But, it not as easy has just converting to caliber and rotor.

1. You need to change the Master Cyclinder
2. You need to change the proportioning valve
3. You need to replumb all the rear break lines
4. You need to rewire your emergence brake
5. You need to modify the rear hubs to except the caliber mounts
6. You need to rework the ABS system to except the new calibers.

So to answer the questions, yes you can, but the cost will greatly outway the benefit. May just be easier to buy a new car with 4 wheel disc brakes

But here a link to a kit that may make this worth your time.
