Chain and sprockets?
For a moment I thought maybe it was a motorcycle, or a project car with a motorcycle drivetrain.

Your car's page:
Details: 3800 Sunfire - 2002 Pontiac Sunfire Fuel Economy - EcoModder.com

Anyway, I don't see how swapping in a 3800 cc engine to replace a 2200 cc engine will improve fuel economy. Unless its actually a performance project and you just want to make some effort to keep it from becoming a total fuel hog. In which case you may be on to something.

But what are the chain and sprockets?? I don't think you'd be changing the gear ratios of a timing chain. It must be something else.
