Ive got a D16Z6 fully built and turboed. Im installing all my valve train at this point and have a comp cam for it. I also have an AEM adjustable cam gear. Problem is the original cam gear had the key way built onto it to keep from spinning on the cam, the AEM one does not, it has the space for a key way. I need to know what kind of key way i should use, is there any particular size? Or am i stuck going to a hardware store and trying to find the correct one?

 

oem honda key should fit. if not call aem up.

 

OEM Honda Key. Get one from a B-Series Motor.
