Well, my belt shreaded on me yesterday a block from the house.
Can anyone take a picture of where it goes? I am not sure of the exact side of the tensioners. Actually someone as unmechanical as me should not own a FI miata. BUT this is my first problem and I am getting to the point where I think all miatas should have FI, they are just TOO much fun that way.
Thanks in advance for a picture.... for stupid .....urr... I mean me.
Mac here are a few pictures to show you how things routeQuote:

Gary can probablly tell you what size of belt you'll need. But I'll give you a few tips. Using a GEAR WRENCH racheting 17mm wrench makes this a snap.
Loosen off the nut on the right driver's side idler pulley and open up the distance between the two pulleys with the adjuster nut on the side of the idler pulley bracket. Put the new belt around the crank pulley first and around the outside of ps and ac pulleys, run it up between the two idler pullies, then around the nose pulley of the sc. It will be a tight fit but use a wrench on the nut to rotate the nose pulley and the belt will feed itself on. Then adjust the idler pullies to get enough tenson on the belt so that there is about a 1/4" flex in the belt. then retighten up the driver's side idler pulley bolt to lock the idlers in place. Kinda hard to determine what is tight enough so go for a spin and see if the boost is maintain thru the rev range. If it drops off you've got belt slip and you'll need to tighten it a little more. Too much tension and you'll overstress the nose bearing of the SC. The belt will intinally stretch more when new and you'll need to retension after a couple hundred miles. Over the life of the belt you need to maintain the tension because the belt will always stretch. Probablly the reason yours broke. You'll become handy doing this after a few adjustments.
Only use the GATES brand belts (they are also available at NAPA as their own brand). The GATES are usually available at O'Rielly's. Gary has a chart on his site that lists the belts for your SC setup.

Hope this helps. Call Gary on his cell 214-280-6172 and he's always willing to help out his customers. He'll be in the shop Sunday.
OK, I followed instructions and everything seems OK. I wish I was in town this week to let Gary look at it as the boost gauge seems to read about 6 or 8 and I am sure it was higher before. I don't think it is loosing boost (belt slipping), but I also hope it is not too tight either. Idle also seems slightly different or maybe I am just now taking notice. I will get it looked at next week. (And get a new backup belt.)
Thanks for the help.
