Do I need a new timing belt or a whole kit?

What is your question?

Recently, delivering sandwiches from Jimmy John's, I started to smell rubber. Pulled to the nearest parking lot in which happened to be an auto repair shop. I'm completely lost so go over and ask their mechanic to come take a look. He said timing belt because the smoke was coming from inside that white compartment. If it didn't pop could that mean its loosened? which may explain the scraping noise from under the hood? It's got swapped with a '95 civic engine, I think d15b6, though I'm not positive. Said to have around 160k on it.
