I have an 1983 subaru, GL 1800 does anyone know what the compression should be?

If it's carbed, somewhere in the 140-175 range should be good.

Actual numbers vary, and are not important. What is important is that the cylinders be within 10-15% of each other.

 

Numbers can vary - I've seen as low as 125, and as high as 220.

 

I would say that 80-100 would be the low end.

My bro's reconditioned EA81 gets 170 in all 4 cyl'ds. Anything under 120 isn't too good. But GD is right, more important is the difference between all 4.

 

Oh, you are messuring in PSI right? If not, these figures may look a little weird.
