Default if i get 84mm wisecos for my sleeved b18 will compression be similar

i want to get 84mm pistons for my sleeved gsr motor, but wiseco doesnt offer any under their "b18c1" section, so i was wondering if i could just use their "crvtec" pistons because they are 84mm. wiseco sells 84mm pistons for crvtecs that are good for a 8.4-8.8 compression ratio. will the ratio be the same on a gsr motor with a gsr head?

compression ratio will be determined by the dome CC of the pistons, what the exactcompresion ratio of the piston is right off the bat.

the compression ratio should be raised by the gsr head combustion chamber, and headgasket will also determine the compression ratio..

might be a little more might be a little less.

what kinda whp are you lookking to make

well i already made 400 whp on 93 with my gt3076r, 81.5 wisecos, and eagle rods, so now im basically looking to max the turbo outwith a sleeved 2.0 setup. will getting the 8.4-8.8 compression pistons at least keep me in that range or would it be wayyy off
