I went to http://www.cppistons.com and looked for aftermarket pistons. I saw that the b18c5 has the same bore as my b16a. So my question is can I use the b18c5 cp pistons in my b16 block without any modifactions? If so that would boost my compersion ratio to 11.5 accourding to the web page. PLease let me know all I need is my pistons and my motor will be complete.
