Depends on the year. After 89, the blocks, and top ends were the same. With the main difference being the crankshaft, pistons/rods, intake and turbo along with the addition of the balance shaft assembly added to the 2.5L.
Before 89, there was a special "tall block" for the 2.5L, but it wasn't available in turbo, only TBI and was 13mm taller than the 2.2 block. Had one in a K-car, took two trips to the parts store for the right timing belt. To tell them apart, the 2.5 common block will have a deeper, more squared off oil pan to contain the balance shaft assembly. Also, the 2.2 is less common after 89, since the base turbo and non-turbo motors were all 2.5's, with the exception of the P and L-bodies sticking with the 2.2. I'm sure there is a way to decode the engine numbers, but I don't know if anyone has that knowledge posted anywhere. A common block 2.2 can be made a 2.5 with just a crank, piston and rod swap and vice versa.
