Generally speaking, if you have properly maintained and not abused the engine, the timing chain should last until the engine is worn out. If you find that you have any burned valves, by all means replace the timing chain, pulleys and chain tensioners.
But a timing chain is not like a timing belt. A belt will wear out after 80K to 100K miles. The chains do age, but since they are constantly in an oil bath, if you've kept the oil clean the chain should last a long time.
The 4 cylinder Saturn's all had timing chains.

The 1994 infiniti G20 does not have a timing belt, thus you can't replace it even if you want to. The G20 has a timing chain and does not need changing ever!
