What's the stock timing suposed to be ?

And what RPM should it idle at?

Keep in mind this is stock no mods other then exhuast.

i belive it should properly idle at 500RPM your car will shake but its normal, and it will oviously be higher in colder temp.

Idling your rpms should be at 750 with a manual trans. The timing is something like 18 degrees btdc. When your timing it you want the red mark on the crank pulley to line up with the timing mark on the block

stock timing is set to 16* tdc and idle is 750+- 50-100. Some values make this change depending on ecu used. Please remeber to jump the service connector before setting ignition timing and follow your service manual instructions.

15 degrees tdc and idle should be 7000-9000 rpm
