Compression question
Hey guys can anyone help me with a compression ratio question, I have a B20b block with stock rods, JE 10.5 pistons, OEM headgasket,and PR3-4 head. I found this link,http://www.c-speedracing.com/h...c.php ,on another site and filled it out but not sure if I did it right, the only thing I'm not sure about is piston dome displacment and stroke I put 10.5 for displacment and left stroke stock, did I do it right??? if anyone could help I would just like to know what my comp. is thanks.

Re: Compression question (hybrid92b20)
10.5 is not the displacement height........CTR's are only 8.6 cc. If you ordered a 10.5 cr piston and you have a stock head then your CR will be around 10.5. Good Luck!!!

Re: Compression question (NJIN BUILDR)
If the compression height of the B20 pistons and those JE's are different then that CR number is wrong. Does anyone know the compression heights for those JE's and the B20 pistons?

I don't think so...............If the dome on the piston rises It will be positive not negative.
Maybe your saying the dome takes away 1.7cc of the combustion chamber volume????
