You using the stock pulley?
The stock pulley will slide right on/off by hand.
The performance pulleys are a different story.
I once had to remove a fly pulley from a Kawasaki 636, had a puller on it with breaker bars on the puller for leverage, and even then, I was putting everything I could muster into twisting that thing, when all of a sudden came a massively loud POP!! and everything in my hand just went loose. Scared the bejesus out of me. I was certain that I had broken something - either the pulley or the tool. The puller was sitting loose on the pulley, and I probably spent 10 seconds trying to find out what I had broke before I realized that the pulley had come nearly all the way off the crankshaft. Slid it the rest of the way off in quiet excitement. Has nothing to do with Miata pulleys, but it reminded me of that story.

Haha I've done that sort of thing a few times. Scary as hell. Yes I have the factory pullies. So that solves that delima. I guess I'll need to ten the press tool when I get this in. Maybe a stupid question. Is this press/puller like one I can get from vatozone or Oreallys?

I guess I mis understood how the stock pulley/damper is setup. I understood it as, the inner race of the damper had the keyway, slid on the crank and was held to the crank with the big bolt. then the pulley bolted to the damper with the 3 small bolts. I could not separate they pulley from the damper after undoing the 3 small bolts when I did the timing belt on my car. It was easier just to undo the big bolt and pull off the whole shebang.

Buyin the press tool might be a worthwhile investment. The tool might be heaped than a tow home depending on distance. Pain in the ***, but from what I can see the new pulley would be a better pulley for a stressed engine. Do you break timing belts often? I'm not a track guy.....yet..... But is there something I should prepare for? I assume frequent inspection and proper change interval would eliminate 95% of most peoples failures. Never known someone who broke one that actually paid attention to their cars. Usually it's the stereotypical chick that has 150,000 + on the stock belt.

I had an OE belt come apart on me. Never had a problem with the kevlar belts.
Just keep the tools to press it on/off in the track spares box. With the right tools, it's not a big deal.

The price difference between the regular belt and the blue is a no brainer. Even in my really broke moments after seperating I go the blue one. Well had the employee discount, that helped I admit. Oddly I know this probably doesn't matter, but I've had both belts new in myhands and the blue just feels better. Placebo effect?

The blue belts are kevlar? Sweet. How many hours do you put on them for a track car vs. how many street miles? I've already thrown away two since I replace them every season.

As for fixing the problem? No idea, I don't go fast enough.
