OK, but like you said before, the wrist pin was moved up in the piston on
the A3 block, so as to preserve the same stroke (am I right so far?).  I
figured the A3 pistons would work with the longer rods and preserve the
same overall stroke...guess not?

Peter Tong?  Coming from the 1.8 I have, I'm sure either motor would be an
improvement in 'snap', but probably also a step down in high rpm
performance...if the short rod 2.0 is as good as you say (and for sure it
would be cheaper to buy a complete short block rather than mix & match
bottom end parts), that's what I'll go with.  Thanks!
