What #'s should I be looking for when I do a compression test on the ka24e? I have heard 150 for the ka24de, I know it is probably not the same! But is 130 good? I don't know ??? Your response is greatly appreciated.

130 is low. Did you have all the plugs out AND the butterfly valve wide open?

By butterfly valve do you mean the throttle body or what?

when you take a compression test, make sure you have all the spark plugs out, the fusible link for the fuel injectors removed, and the accelerator pedal fully depressed (wide open throttle).
