What do you mean you dont have the crank pulley that spins the power steering? Is it aftermarket? You know the stock crank pulley is 2 pieces.

I dont really have an opinion on those pulleys but I do know there are name brand alternatives to all of them. I guess this is one of those you get what you pay for things....

these guys are actually located down the block from me. I picked up one of their first sets. Quality is amazing for the price. They are are stock sized replacements from what I remember. I have a feeling that maybe the crank was a tad smaller but I can't remember now.

Sorry what I meant is that I have the stock pulley and the front outer pulley is missing because engine is taken apart and it got misplaced but I do have the pulley that drives water pump and alternator.
Thanks

I just looked at a bunch of pictures from my HD and I only took pictures comparing the greddy, oem, touge factory wp pulleys. The touge pulley is just a tad taller the the oem WP which may require you to remove the thermostat housing to install. Mine was already off so I'm not sure. I believe the crank is the same size as oem.

here they are minus the PS

Oh.... then you should look for another crank pulley man... it would be wayyy easier. Tpcplaya says theyre good so if you want the shiny blue pullies then go for it.

make a life choice bro.... this is the moment youve been waiting for

So with that kit can I use power steering and a/c with there crank pulley.
Thanks

the touge crank pulley is one piece so you would remove the oem completely and replace with this one. This doesn't mess with the needle bearings at all like some of the aftermarket pulleys.


edit: yes to your second question

Depends what you want to do with it.

For a daily driver, the stock pulleys work very well (with the exception of the stupid brittle power steering compressed plastic pulley which should always be swapped out IMHO)

For a show car, these brightly anodized pulleys offer the "blingy-blingy" factor well.

For race duty or high performance, I would go for a recognised brand of alloy pulleys from Pettit or similar. But thats just me.

Underdrive or stock diameters, depends on what you want out of the car, personally. Underdrive is probably not a fantastic idea for a street driven car.

I run a very slightly (2mm smaller OD) alloy water pump underdrive pulley on the street. Reasoning is that it may help stop cavitation at high rpm. It also makes sourcing water pump belts much easier from my local parts store.

I am also about to swap in an alloy power steering pulley, because I dislike the fragile fiber plastic stock pulley. Stock sized.

And also about to swap in a billet tensioner pulley because I can. Stock sized.

Apart from that, on a daily driver at stockish power, I have no need to go further.

OK so if I remove the oem crank pulley all the way then this kit would be what I want since the pulley is $200 new from mazda.

and i'll put these up for forum reference. This is comparing the pulleys to the Greddy Alt & WP pulleys and the oem WP pulley. Power steering is identical and so is the crank in terms of size.

I want to reiterate that imo, the touge factory pulleys are very high quality in terms of materials and build. They are not you cut of the mill ebay pulleys.

They were WAYYY thicker and more quality than my greddy (style? bought 2nd hand) pulley set ever felt. For the money...I will almost guarantee you won't be unhappy. Most other places charge this amount for a power steering pulley alone.

I think I will just get the kit it looks nice and I would like to replace the plastic pulley as well any ways thanks for all the help. BTW any chance of belt slipping on water pump pulley since it is so smooth.

TpCpLaYa

iTrader: (10)

smooth is not why the belt would slip(oem is smooth)...contact area, or lack thereof is why it would.

If you do not have a airpump installed the only proper way is to purchase an idler pulley. Mine is shown in the picture. The GReddy pulleys are wider to try and make up for this, plus they have little grooves which always seem to rub away, but it is nowhere near what is needed. Over tensioning the belts to aid in this put stress on the main bearings which lead to premature wear.

I ran without an idler for a few years, wish I hadn't, before getting an idler pulley and when I finally pulled my engine is had catastrophic bearing damage. Linked? Maybe...maybe not, but it's been documented to wear them faster.

Ok so I should get the pineapple racing idler pulley since I am removing air pump, I am guessing I could chuck up water pump pulley in a lathe and put a knurled finish on pulley to prevent slipping.
Thanks

Get the idler and don't touch the water pump pulley. The wp pulley contacts the smooth side of the belt and with the idler pulley you should not have any issues with a slipping wp pulley at high rpms.

some other options here. This pulley kit looks to be identical and it says the main pulley is underdriven, which may be true of the touge factory set. It's been a while since I had the oem one to compare. http://banzai-racing.com/store/93+_r...lley_belt.html

Is there any potential problems with a undersized main pulley.
Thanks

^I haven't had any issues with it.

IIRC the diameter is the same, but it's the wall thickness of the aluminum Touge wp pulley that prevents it from slipping on without loosening the t-stat housing.

TpCpLaYa

iTrader: (10)

That sounds right....since it needs to squeeze thru the small gap between the wp and thermostat housing. I put pics above showing the dimension differences

BTW...very nice engine bay TpCpLaYa.

Thank you kind sir....I'll give the semi-lighting and shadows credit for that haha. You've got some nice bling going on for you as well.

+1 on the touge factory pullies....i just got mine the other day and I love them for the price. The main pulley is a slight under drive but the main reason I got them was because I broke the stock power steering pulley and this was the cheapest kit that included the PS pulley.

and you can get them in any color

We sell them for less and we stock the Pineapple idler required for smog pump removal. We also have the proper length belts available for installation.
