I have a fully built b20z w/ a gsr, head all moter setup (11.8:1 comp). When i put the motor in there was no place to bolt the black box for the pcv valve up to, so i did not put it on. So as of right now i am running with no pcv valve. I have a catch can and have no idea where to hook the hoses up to. Can someone help me with these problems. i posted on another forum and the people had no idea.
