Combining Boxster Blocks
 

I recently had a catastrophic failure in my #4 cylinder, it seems the connecting rod broke and then pushed the piston through the bottom of the bore. took out a big chunk of the sleeve and block. I do not think it is fixable ? I found a used engine online that the owner claims had a failure in cylinder #2 . I am wondering what peoples thoughts are on removing the right hand side of one engine and installing it on an other? in theory it seems OK but do you think i will run into mating issues with his connecting rods on my crank shaft?

I wouldn't mess with it. Just buy a complete used engine. They're like $2000-2500.
