Does anyone know the cc per piston? I was told that c-speedracing's figure (3.64) was incorrect. Can anyone confirm?

Thanks!

well i dont know exactly the P73-A0, but my P73-00 at .25mm over were only 2.25 so i would say they are similar to that

I have some p73a pistons in my garage but have no way of measuring them

 

send me one and I will CC them

 

 

JDM SiR (P72 00) +2.52 cc

B18C5 (P73 A0) +3.64 cc

JDM Spec R (P73 00) +5.96 cc

B16B (PCT) +8.63 cc

 

i know for a fact the p73-00 are not 5.96. they are 2.25ish. I cc'd them recently

 

if you can share that exact spec, then that would be great. because when you plug it into a ITR block/head volume, does it work out to 11.1 static CR ?

 

if i get a chance this week, i will take a couple of the common pistons we have laying around and document (with pics) the process for everyone. also, i do not know the exact deck clearance on them either. i will do some research and post some results up though

if you can find someone to send me a piston, i will cc one
