on cars that came with dealer installed AC, did it have the same bracket as the factory cars that had both the PS and the AC tensioner on it?



im ditching PS, but I want to keep the AC, I would like to lose that monster bracket



anyone have any input?

There are 2 different brackets for cars with a/c and no PS. The sanden and nippondenso have different bolt patterns. In either case, thats the bracket you want. It small and only has a single idler pulley.

Is there a bracket for cars with PS (speed sensing aka S5TII) with no AC?

I did, he was too busy eating out General Tso to answer me

I've got an a/c bracket, w/ no p/s, already in a box to be shipped (someone wanted it then changed their mind). So there are 2 different kinds? How do I know what kind mine is, and if you can use it?

I think the easiest way is to measure the distance between the 4 bolt holes that bolt the a/c compressor to the bracket. The nippondenso and the sanden have a slightly different bolt pattern.

Baldy 06-15-2005 02:51 PM

I'll crack that box open and take a measurement tonight.

Baldy 06-15-2005 05:29 PM

I tried to measure from center of hole to center of hole, and got 5 1/16" by 3 1/16" (give or take a sixteenth).



I have 2 of these (both are the same size), so if anyone else is interested let me know.

Rob x-7 06-15-2005 07:21 PM

I want to keep whatever compressor is in the car, I dont want to lose my ice cold freon.



im told this is the non ps bracket, its pretty easy to tell from the PS one, just not sure if they came both ways or not, plus Im not sure if I can even get a good measurement out of mine on the car now without taking it off, its a slight bit off Ill have the welder fill it and I can re-drill I suppose



Im going to run cosmo ribbed pulleys and switching the stock v-belt pulley on my compressor to a FD ribbed pulley as well.

COSMO RIBBED PULLEYS WILL NOT WORK WITH THE AC PULLEY

why not? a ribbed FD pulley ?

banzaitoyota 06-16-2005 07:58 PM

Heres why:



The Setup:

13B Front Iron

S4 NA front Cover

S4 NA Water Pump Housing and waterpump

FD ALT

Cosmo 13B-RE MAin Pulley

Modified 13B-RE Water Pump Pulley

S4 NA AC Only Bracket

Rob x-7 06-16-2005 08:01 PM

a pic I have of a cosmo engine shows it actually having a v-belt for the ac, the set of pulleys I got from a cosmo engine actually had NO ac, lol



your pulley looks like a ribbed and a v-belt as well



so I got a FD pulley coming my way anyhow, otherwise I will use the v-belt for the AC with the stock S4 pulley, either way I needed the ac bracket without the powersteering

banzaitoyota 06-16-2005 08:18 PM

The AC is a V-belt, the alt/waterpump/main is ribbed.



This setup does not have enough clearance to install the V-Belt between the waterpump pulley and the AC Belt Pulley on tha crank



This is after remove the airpump pulley from the waterpump cosmo pulley

you ever see the way they ran belts in the Corvair?



you can do anything with them!

Rob x-7 06-16-2005 08:25 PM

but wait, there is more!



who would have thought you could run a single belt like that?

banzaitoyota 06-16-2005 08:28 PM

Installiing the Cosmo Water pump housing is NOT an option with the S4 Front cover either



[attachment=31874:attachment]



The front cover(s4) interfers with the waterpump housing(Cosmo)



[attachment=31875:attachment]

banzaitoyota 06-16-2005 08:30 PM

it can be done with a custom main AC pulley, but so far I have not found a working combo using stock Mazda pulley combos

Rob x-7 06-16-2005 08:33 PM

I have access to a **** load of pulleys, maybe Ill find something that will work

Baldy 06-17-2005 07:25 AM

So, do you still need this thing?

Rob x-7 06-18-2005 05:33 AM

yes, only thing that might change in my plans is not running the ribbed AC belt



I still need the bracket
