I was able to find out that Rb20DET's have 8.5:1 compression but how do you convert that to psi as i did a compression test on my car yesterday and i was just wanting to see how healthy she is...

My readings were

1) 155 PSI

2) 150 PSI

3) 152 PSI

4) 152 PSI

5) 152 PSI

6) 150 PSI

Are these low/high?

The engine has got 89000clicks on it.

Cheers for any help...

Ryan
