I've searched and can't seem to find the answer. What is the compression spec per cylinder for a 2jz-ge?

I decided to do a compression check on my 1994 sc300 5 speed with 171k miles on her to see if she was still healthy enough to slap on a turbo.

I got 190psi across the board. To me that sounds very good especially for a car with 171k miles, but I have no idea what the spec is...

 

spec is 156-185 or more with 14psi or less difference between cylinders.
