Compatible 13" Logic boards

I have a liquid spill computer. It boots, but the battery is not responding well and the fan is out.

The local repair shop diagnosed it as a bad battery, fan and to be safe a logic board.

What I want to do is make it a Frankinmac.

I want to find out what logic boards will fit in the 2009 body? I am hoping to find a faster processor and board to use IE. 2.53 or 2.66

Any help would be great.
