I have asked this questions several time and never got a straight answer out of anyone. I have a S14 with an SR20DEt Redtop and my speedometer reads incorrectly. I have tried a JDM S13 speed sensor & US Spec speedsensor and they both read the same. It acutally reads 2x fast. So then I tried a S14 us spec speedsensor and it reads 2x slow. Do I have a wiring problem? or could it be that I need a miracle? I heard someone mention that I would need a Z32 300ZX speed sensor becuase of the coilpacks vs. the distributor. Can anyone shine some light on this one?

Thanks,Dan.

I cannot answer your question, but I have a s13 240sx with an s14 sr20 in it. The speedo reads 2x slow, and I still can't figure it out..

I have the JDM cluster, and it still reads 1/2 of the actual speed.

I'm beginning to wonder if anyone knows the answer to this one? Could it be wiring? or something else?
