What is Perfect factory compression for SR20DET? (i searched)

[sepulchral]

I searched "perfect compression" and it showed abunch of cars for sale. Anyways I think its 185psi on a fully warmed up motor. Is that right? What is good compression on a cold motor?

156 psi is oem spec considered max. Check your local FSM.

He just wants to know the stock compression on a stock motor that is not installed in a car for testing purpose's i believe... Good question. I'd like to know as well.

No shit, I moved it here. :blah: :cj:

[racer98]

it depends on the motor and what version it is

S13 Red, S13 Black
S14
S15

also other things too consider is if the motor has an After mkt H/G

the best place to get the Nissan Facotry spec for compression is in the Service manual for the Spec year of the SR20DET your talking about.

does anyone know the stock compression on a s13 redtop?

[the head]

My s13 black top was 150 all across IIRC manual for S13 sr states a range 130-156 and a spread of no more than 4 or 5 psi across all cyl
