i got the same exact problem, i can't find the intake cam sprocket for sale only the exhaust one is the same. the timing chain kit on ebay seems to have the proper parts besides the intake cam gear and
http://www.courtesyparts.com can supply you with the rest of the stuff you need like bolts and gaskets when you're doing the timing chain kit.
so that begs the question, does anyone know where to buy that intake cam sprocket for the s14 sr?
btw, does anyone know the part number for the variable valve timing actuator or where to even get one since that poses a problem and should be fixed while doing the timing chain on a s14 sr.
