You are right about how the s14 pulley is installed on an s14 throttle body but the pulley sits closer to the throttle body on the s14 than the s13. See the "free body diagram" for clarification on what I mean by bending. The throttle cable pull is much closer to the throttle body on both the s13 and s14 from the factory than what your working with. The yellow shows an exageration of how the axle is bending once the stop is reached. The OEM s13 pulley is deeply concave to move the pulling action closer to the throttle body.
