I need a miata 1.6 big nose harmonic balancer/crank pulley/ whatever it's called. Turns out I don't have one for this motor.

I could also make due with a good 91.5-95 (part#B3C7-11-400) crank pulley boss if anyone has one of those around.

Don't have a spare - but FYI you can use a 1.8 unit if you swap out the water pump pulley and the alternator. Gets you a higher amp alternator as a bonus. Use a 1994-97 unit, the NB ones aren't internally regulated.

So that's an option.

Thanks for posting options! I had considered it, but I have a small army of 1.6 alternators and was hoping someone had a crank pulley with boss laying around ☹️ Interesting news is so far as I can tell the bp powered ford escort has the same harmonic balancer with v belt and they're fairly cheap NOS, but don't have the boss. So I guess I should clarify that I'd take a good 91.5-95 crank boss alone as well go get me going if anyone has one for sale.

I can pull one off my parts car tomorrow. Let me know if you need just the boss or the whole assembly and we can figure out a price and shipping.

Well poop, I ordered a new boss because I'm impatient ..... I might need a few other odds and ins and will ping you if that's OK?

No big deal. If you need anything else just let me know.

In case anyone stumbles back across this thread. Ford part# F1CZ-6312-A is identical to the 1.6 Miata big nose crank pulley/harmonic balancer.
