If I'm reading it correctly, his signature says '96 SE-R with a W11. That would imply that he has an SR20DET.
If that IS the case, a 1.6 speed sensor won't even fit the SR transmission.
Also, the 1.6 and 2.0 gears have the same amount of teeth (32 or 36, can't remember). I know, cause I've compared and counted them myself.
What you DO need is a speed sensor from a 91-92 NX2000, which had a digital cluster. Now, an NX2000 never had a digital cluster, however, Autozone lists a speed sensor that works perfectly:

It's the top one, or the SU4055
Buy it, install it, and your speed is dead on. Trust me, I've done the same.
The problem is the "non-digidash-speedsensors" have only half the pulses per revolution (8-9ish) than the "digidash-speedsensors" (16-18ish).
