Does anyone know what the compression ratio would be with rbc pistons in an f23a4 block and f23a head? I've searched and the only ones really mentioned were k20a2 and k20a3 pistons, but not the k20z3's.

From another thread:
"the K20A2 pistons should get you around 12.3:1 static. K20A3 will be lower, around 11.5:1 static."

 

Sorry, meant to say f22a head. Damn autocorrect.

 

I use the compression calculator for h/f series and just change the piston measurements...

 

I tried that already. What are the specs for the rbc pistons? They're not listed on the comp calculator. Comp height and dome cc.

 

Lol you don't need to be looking into this if you have to ask more questions. I gave you the answers. Yes you have to look up the piston specs and enter them.
