The H20 is, here in the states, a forklift engine. It's basically a
3-main U20. While Nissan specs it as a low-RPM engine, several
Roadsters have H20-based engines in them and reportedly run fine.
It requires the H20 crank but I believe all the other U20 parts (rods,
pistons, chains...) swap right over.
I'm not an H20 authority. My suspicion, though, is if you have H20 parts
and want to put them in a U20, you may want to reconsider. If the parts
aren't identical, I would imagine the U20 parts are heftier. That is, unless
the part number is identical, a U20 piston is going to be stouter than an
H20 piston.
