I was wondering if the 2.1L long block can be used as a replacement
longblock for the 1.9L.
I'm considering a rebuilt motor and was wondering if the 2.1L will "plug in
" to the 1.9L hardware.
I'm sure the water pump is different, but other than that what do I have to
look out for when converting.
Maybe even to a stroked counterweighted 2.1L..........who  knows?
