150-155 across the board good compresion?

[95GST2841]

thats the results I got from when I compression tested my motor..

lowest being like 148 highest being 155

motor has 124k is this normal?

Nope it isn't normal. It's better. New readings on a 2g are usually around 185 peak. So you're doing good given the mileage. My 1g was reading 110 before I did my swap.

Most of what you're looking for though is consistency. You don't want variation across the cylinders. So you're good there too.

1g have lower compression.

Your conmpression reading 155 across is great.

 

[hereitcomes]

compression should be 150 across the motor. Each cylender should read 150 or somewhere close too it.

1g have lower compression.

Yeah, but... he's in a 2g....

They're all close, so it should be fine. Did you warm the car up first? Did you hold the throttle open when you did the test? Those might raise your numbers if you didn't do them.

I was refering to what he had said.

You should not have more than a 16 PSI drop between the cylinders.
