i am looking at a GSL-SE for sale. i have the money and looks good but before i give the guy the money i want to test the compression. one of my mechanic friends has the compression tester tool and is coming with me to check the car out one final time. i was wondering what is an acceptable compression for a 13B with 138k miles on it. cause if its not to a acceptable level i wont buy it. thanx.

 

its an 85 GSL-SE by the way

 

Anything above 95psi on all faces and about a 5psi difference between them.

Higher is all was better

Be sure to pull the one way valve on the compression tester so you get each rotor faces pressure and no the over all pressure.

Hope this helps
