Perfectly interchangeable. You will need the 1.9 water pump to match the
cooling system in the van. Using a later exhaust or a short oil filter
will allow to use the 2.1 oil cooler. I strongly recommend this. If
using the later exhaust, you will also want the later rear engine mount
(engine mounted casting) so you can use the later muffler brackets.

Subject: will a 2.1L long block wrk with 1.9L FI and hardware?

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?
