i don't know of any p3 piston. i'm guessing that you're talkin' about one of the following...
a gsr engine with pr3 (USDM B16A) pistons will yeild a 11.4 compression ratio, a gsr engine with p30 (JDM B16A) pistons will yeild a 11.6 compression ratio.

all that can be found at http://www.c-speedracing.com/howto/compcalc/compcalc.php . that should help.
