Turbo on Stock Civic?

I'm considering getting a Greddy Turbo for my stock Civic. It's a '94 Civic EX, with 112,000 miles on it. I was wondering if it's even a good idea to get a turbo, since the engine is old and has many miles on it. Also, do I need to get/replace any parts for my car (clutch, brakes, etc)? Does the turbo add a lot of noise to the car, such as exhausts and CAIs do? What would be the estimated cost of labour in installing the turbo? Thanks
