RB25DET speed sensor

[Mi BEAN]

Ok i just found out that im running a ka speed sensor in my rb25 tranny. well after research i found out that the rb needs the sensor to go deeper (thats what she said) to get the right reading. here is my question does anyone know of an interchangeable sensor off another car or where to get an rb25 speed sensor?

I heard you need the na z32 speed sensor

if its in an S14 I might work just fine with the speedo.

Mine did

could be true. i just wonder about the right gearing and the right length. i found this link about it and the first two pictures about speed sensors look like the diagram i seen before but then the picture after that they look short.

My s14 worked fine also. No real calibration was needed. Rb25 sensor btw.

it was the RB with stock S14 cluster

I pulled this from a search. notice how the gears are different on each one? maybe the actual sensor is the same but the gearing is different??

When i'm going 50mph my speedo reads 15mph haha. I have the rb sensor, what if i put the KMPH guage on? Would that work?
