I am doing a compression test on my '93 D15B7. I was wondering what the specs are for it.

Thanks

 

Check compression with engine at normal operating temperature and throttle in wide open position. Prior to performing test, disable ignition and fuel injection to prevent fuel from being sprayed into cylinders while cranking engine. Ensure the battery is fully charged and that cranking speed is 250 RPM. Standard reading should be 135-184 psi. The maximum variation between cylinders is 28 psi.

 

Thanks

 

Really only 135-184?? I am doing a compression test on my d15b7 also. Because this car is soooooo slow! I punch it and it goes no wheres. Lol but im gonna try doing a comp. Test..... gotta start somewheres....

 

In the future, unless you are contributing something worthwhile to an old thread you should skip it (especially an 8 year old thread).
