Engine Swap / cheap or free mods

Whats a decent price for a used B18 out of a GSR? I am planning on that for a summer project for my civic and need to start looking at used engines. I am going to rebuild it for use with a turbo. Any helpful hints?


****Also I am looking for any cheap / free mods i can do on my 97 civic right now to gain a little faster time in the quater mile.
