like the topic says, JDM 2nd gen b16a head and b18c5 block, i know that they can go together but i was just wondering what compresion will it yeild when mated together???? JDM 2nd gen b16 has 10.4:1 and b18c5 has 10.8:1 i believe, so what will it be when mated together????

 

try doing a search for compression calculator. i cant remember the name of the site exactly. i think it might be cspeedracing.com or something like that

 

It will have the same compression ratio as a US ITR motor. 10.6:1
