You need a DOHC tach.

See the search button up top? It's there for you to look up information that has been posted/asked/re-posed/re-answered and etc.

if you use DOHC tach, which speed sensor do you use? SR? KA-E?

[95zilvia]

You just use the sr speed sensor.

So... if you're car is a SOHC, and you want to run an SR, you need to swap to a DOHC cluster. Or you could just swap the tachometer, but yeah, just use the cluster with your front clip.

If you need a DOHC cluster for an SR, I got one you can have for cheap. It's in good shape and been sitting here unused for about 9 months. Email me at [email protected] if you are interested.
