Hey
I have an 03 v35 skyline. I wanting to install my tomei pro cams they are 280* 11.3mm lift. I was just wonder if they are able to be installed on the stock bottom end? Is there any valve piston clearance issues? Or any other issues cheers.

 

Your best bet is to call Tomei, or another reputable shop and ask them directly. I don't know much about cams but I would think you will be fine but why you do it? You know in order to get the most out of cams you need to get a new intake or mod it correct? You know its not a simple job to just change the cams correct?
