I am in the process of tearing down a B20 to put a K cam in it, do some headwork, and possibly re-ring, etc.
The motor was recently freshened up, and it has a seemingly brand-new fiber cam gear in it, mated to a much older looking steel crank gear. My questions is whether, if pulled with care, these fiber gears are reusable. Some people say no, others say just be careful with it.
If it must be replaced, is there any sense replacing it with an aluminum gear and mating that to the existing steel crank gear? I know the best scenario is buying matching steel gears, but that's a lot of money I'd like to avoid.
Any thoughts on my best option?
reuse fiber gear?
buy inexpensive aluminum cam gear only?
pony up for a steel gear set?
Thanks,
Tyler
