So i bought a jdm b20 (p8r) a while ago, but i want to know which model it is so i could tell the compression ratio for future upgrades.

On the block says:
B20B
5200758

And on the head it says:
P8R-11

It has a knock sensor.

Any other reference that i should look?
Can't find the year stamped. Where should i look?
Thank you.

From what i could see is either 9.2:1 or the 9.6:1 depending on the year...
