interference motor?

hi guys. i recently picked up a 1990 protege for my wintercar. the manual says to replace timing belt every 60,000 miles, and my car has 135,xxx. i removed the timing belt cover and the belt is pretty worn. im just wondering if its an interference motor or not(sohc, 1.8L). im planning on replacing the belt over my xmas break from school, but im just curious if it will blow the motor pretty good if it breaks before then. thanks

ok - for all those who search for this in the future- its a non- interference motor, so if the timing belt breaks, the pistons wont smash the vavles
