Is it really necassary to swap the SR speed sensor with the KA sensor on a DOHC cluster?

Nope, they both use a red gear, they are the same.

He's right, I had to hardwire mine because the plug was missing but I never switched the sensors.

Is there a way to, or device that will let one re calibrate the speedo? I'll be running an SR in a car with 3.55:1 final dif ratio and 16inch rims running 225/50 tires. Not exactly stock numbers for a 240.

Dakota Digital makes a little electronic box that will recalibrate pulsed signals (i.e. tach or speed signals, or anything else like that).

While we're on the subject, From the front of the tranny ( engine side ) working back toward the driveline, which sensor is the speed sensor? ( 3rd? 2nd? 1st? )

Really?! So swapping the KA sensor off a 1995 into a s13 sr20det tranny is NOT necessary?
(just need confirmation)

Actually Asad, with a little ingenuity and a frequency generator for tuning, it's possible. I'm using a JDM speedo as a 180mph speedometer, have done two of them so far.

PM me if you're interested in having a speedo calibrated.

Yes, they really are the same.

Apexi Rev Speed meter can compensate for different tire sizes. If you can calculate your % difference from stock due to tires and gears, you can input that and it will be accurate.

The speed sensor is 3rd, it has a screw holding the sensor in.
