What is normal cylinder pressure readings when doing a compression test on a B16 with JE 9:1cr pistons?
I know what the stock cylinder pressure readings are for the factory compression ratio, just looking to figure out what they should be for lower compression.
Is there a rule of thumb to follow when lowering compression for forced induction?
Thanks for any info.

my 9.2:1 pistons on a b18a w/ b18b head produced about 200psi. but then again i was told they were 9.2:1 and they never came in official packaging etc... so i dunno. You should see somewhere between 180 and 210, numbers don't matter THAT much, so long as they are all within a couple of psi of each other (for a rebuilt motor).
