SOHC cluster doesnt work with SRs, you'd need a DOHC cluster/tach.

You may need a different speed sensor. if the sensor in the sr hasn't already been changed.

why would he need a speed sensor? he is complaining about rpm not his speedometer

OP yes you need a dual cam cluster for the speedometer to work for your sr basically any s13 past 91 or newer, check your local junk yard I got one for 20 bucks at my local pick your part.

He shouldn't need anything because this info has been documented, and that's the same reason Jasonx63, should have gotten it right!

I believe you do need to use the KA sensor, but as was stated, the Speedo was not even a concern, the fuel guage was

Not sure what this means

As for the fuel guage, that should have nothing to do with the swap, it's a function of the chassis, not the engine, so check your fuel pump cradle wiring and see if the guage itself is getting power / signal...
