Compression test results...a bit high****

[GSXlaunch]

I just did a compression test on my 91 GSX 4g63 turbo engine with 116k miles. Here are the results

#1 - 170
#2 - 178
#3 - 170
#4 - 180

Are these numbers okay? Thanks for the help.

I heard 150 is spec for these cars. Shop manual says so also.

Wow, thats a bit high considering the miles and that factory is 164 I believe. Was the test cold or hot and was the pedal to the floor?
