Narrative:

Climbing through 1000 ft AGL, #2 engine had serious compressor stalls. First officer, who was PNF, took care of the qrc items, and the stalls subsided at idle. Captain coordinated return to runway 27L, and made announcement to very concerned passenger and flight attendants. We requested 15-20 mi turn-in, to give time for checklists and to get settled, and approach was very accommodating. Made normal flaps 15 degree landing on runway 27L, released emergency vehicles, and made normal taxi to gate. Maintenance found engine bullet fairing snapping off and laying in the intake. Callback conversation with reporter revealed the following information: the reporter stated the airplane was a B737-200 with JT8D engines. The reporter said the fact the engine guide vanes are forward of the first stage fan prevented the nose bullet from entering the fan blades. The reporter stated the engine was not shut down, as no stalling was present at idle power.
