Where can I find an inexpensive engine for a 1984 Honda Prelude?

I dont have a lot of money to invest into the car but wanting to p it along in the family like it was given to me. Can anyone give me the name of an inexpensive dealer or salvage yard (on the east coast) where I can get an engine (and some spare parts) to revive this soon-to-be family heirloom? Thanks for your honest input!
