I was woundering the compression ratio of a b18b1 engine. i know its 9.2.1 but what is that in psi form? im about to turbo my integra but i wana know what its supost to be incase mine is higher than stock so i can lower if i need to. it seems higher than its supost to be.

 

u dont need to lower it u said in your last thread u only wanted 5 psi and like 220 hp. u dont need to do anything to the motor for these numbers. and i still say the gsr swap is your best bet.

 

lower compression is also more reliable, im just curious on numbers of what a stock psi is supost to be.
