hey ppl me and my friend compression tested my car today. 180 psi in each cylinder. is that good bad or evil? i understand its good that they are all the same but i dont know if 180 is good or to high . input pls?

I'm not gonna lie, I don't know the answer. But I know it's posted in here somewhere. I think 180 is perfectly fine. Do a search, you should findi it

I did some searching myself, looks like 180 is alright. A lot of people had number like 190-205, so I guess 180 is good. Just replace the spark plug seals.

yeah cuz there was a lil bit of oil on them because i need a new valve cover gasket. hmm i might need new spark plugs too. so im good to boost?

Read what Midniteracerx has to say in that thread. You should do those things, although it's not necessary. If your gonna boost, your gonna need new spark plugs anyways. 1 or 2 steps colder.

want a ecu or not?

[prodigymb]

yeah i guess i do want an ecu. btw i did a compression test again with a proffesional tester and not a pep boys one and it was much lower it was 150 in all 4 cylinders instead of 180. i told my mecahnic about 180 and he was like seems a little to high, and he said it was prolly the guage we used b4, he said it should be around 155-160 and i do the test again what do u know 150 in all 4.
