I was surprised to find no spec. for same at a quick glance in the factory workshop manual. But I'd guess you're looking for something around 110-130? And all six within around 5-10% of each other is a good thing.

I agree with Andy.....the key is to not have too much variation between the cylinders, 5-10% is about right.
I can't honestly remember, but I think my compression was higher than 130, I will try to find where I put the numbers. Either way consistency across all the cylinders is what you want.
