Aside from the t-belt and w-pump, you have to consider the fact that the car is 15 years old and that alot of components might be corroded at this point. Especially if the car spent a lot of time near the ocean or in snow, then it experienced salt. Time could corrode bushings, suspension components, hoses, and such things. You should just account for repairing a 15 year old car.

For example I like my car, also a '95, but I have spent a lot of time and money on it, to keep it running the way I want. Unless you have a special reason why you want an integra, I would just buy a newer car.

If you do decide to get it, as with any car, its a good idea to get it on a lift and take a look at it, and have a mechanic take a look at it, because I guarantee that you will probably have to repair some things, due to regular wear, that the previous owner neglected.
