Externally the 2.2 and 2.1 cases are supposedly the same.  The extra
displacement comes from slightly larger pistons and longer stroke.  Fuel
injection system remains the same.  If you run a 2.1L block in your
Vannawagon that will make it as bolt-in as you get.  If you run a 1.9L then
look at http://www.oldvolkshome.com/19to21.htm.  Not too shabby.

This means if we got our hands on the larger pistons and cylinders and the
stroker crank we could make a "big-bore" high-compression engine of our own.
