I'm looking for an adj. cam gear mfr. who makes gears for the D16A1, which uses 40T cam and 20T crank timing gears. The ZC uses 34T/17T gears like the B series motors.
I've looked into putting 34T/17T timing gears on the D16A1, however the D16A1 has a 22mm crank snout, unlike the ZC/D16A6 which use a 24mm crank snout.

So, anyone know of any other Honda motors that use a 40T cam gear? If I can find one that is the cast spoke type (rather than the stamped steel type) I can make my own, no problem.

Thanks,

I just went out and checked my spare cam gear. It's a 40 tooth cast spoke from an '85 Civic. I assume all of the EW Civic engines would be the same. There is an adjustable gear made for the '85-'87 Si that may work. I think AEM has them.

 

I wondered about that....Some years ago I made an adj. cam gear out of one of those for my old CRX 12v motor. However, I never bothered to count teeth - I sold all my 12v stuff to a local EP class racer last year, along went the gear.

Time to go junkyarding...
Thanks,
