Changing cluster - is my odometer going to be correct?

^ As topic states, I'm replacing the cluster in my Del Sol and was wondering what's going to be affected. My car is the VTEC trim and came with 195/60R14 tires. My new cluster is out of the Si trim, which had 185/60R14 tires. My question is, will the odometer and speedometer read incorrectly? The new cluster is out of a car that has 2% more revs/mile.

How does the odometer work? Do I need to keep my old one, will the new one read too fast? I can tell the speedometer's reading appears to be determined by a small motor and spring, is the spring going to be different in the two speedometers because they're for different wheel sizes? Or is that determined elsewhere?
