well from what i know (not much) heres my answers;
the 4A-GZE was released in both AFM and MAP sensored versions (1 AFM version and 2 MAP sensored versions). The earlier model AFM gze, was less powerful and as its name suggests used an air flow meter and dizzy. As compared to the newer manifold absolute pressure measured gze's that were more powerful, to dintinguish the 2 from a photo look for the coil packs of the MAP sensored one, no coil packs = AFM.
Comparing the 2 engines the 20V and GZE (both stock), the difference is TORQUE, and lots of it. More info on the GZE here.. <url>http://www.club4ag.com/faq%20and%20tech_pages/4A-G ZE_specs.htm</url>
Both great engines, both lots of potential, really depends if u love NA engines or rather some forced induction. Chris
