How similar (or different) are the blocks used for different engines with 
the same cubic capacity.  Are all 2144cc (or 2226cc) blocks the same?  I 
remember hearing that turbo motors squirted oil on the underside of the 
pistons - do these have a different block, or are there just some extra 
components fitted to a standard block?

Anyone got any suggestions?
