[NissanFan81]

Im looking into buying a ca18det for my 89 240, and the guy is going to send me the compression test results tomorrow but i was wondering if anyone knew what the psi is supposed to be for each cylinder so i know its a good engine?

Standard pressure is 171psiThe service limit is 142psi or a 14psi variance between cylinders.

so what should it be so i know its a good engine?

id be happy with anywhere from 145-180 with at most a 14psi variance between highest and lowest cylinders. try to perform the test after the car has been driven, if its done when the engine is hot id be nervous about something less than 155 though, just me. if your planning a teardown, its not as big of a deal.
