cylinder 1= 175cylinder 2=175cylinder 3=175cylinder 4= 165

idk whats up with that last cylinder maybe you have an idea.

Compression test looks ok to me. A small amount of difference between cylinders is normal. What kind of problems do you have or you just wandering about compression? I prefer a leak down test. What are you looking for?

well i was reading up about turboing the motor and was just curious about the compression ratings. in the ka-t section they said anything above 155 and within a 10 psi difference is ok, so i thought it was pretty damn good until that last cylinder. just wondering if thats common i guess to assure myself i dont have a bad candidate

From what I understand the lower compression number in cylinder 4 is common. Your engine seems to be in really good shape.

yep that compression looks spot on.
