Well i just put my rebuilt ZC down in the car , hooked the starter up to turn it over a couple of times to get some oil moving around. And noticed the cam gear looks like a warped bike rim. But my question is what fits , i heard the b16 fits but not sure what i would have to modify to make them work. If there is some where that makes something that bolts right on that would be great, any suggestions??

 

B series gears have the same number of teeth, and the size is the same, but the timing marks are 1 tooth off.

If you check out thezcr.com they have a write up on putting aftermarket B series gears on zc cams.
