There is an easy way to see if the belt is broken. Remove the 2 10 mm bolts from the black plastic cover (middle timing belt cover)on the engine (the ones by the drivers side engine mount) Remove the cover. When you have it off, take a look at the belt. is it broken? If so, you can remove the plugs and look through the holes at the pistons to see if you see any signs of them hitting the valves. Have the mechanic put a new belt on the car, see how it runs. Chances are there may not be ant bent valves if the belt broke while the engine was being started or at low rpm. Even if the engine is gone, you could get a low mileage 160hp b16a engine and computer from a japanese importer to put in the car. It could be done for well under $1500. Dont despair, the 2g integra is a great car and an engine fatality can be the start of something good!
