I found a fourm member selling a lightweight flywheel that I want to purchase but first I need to know some info on it. The person selling the flywheel had it resurfaced and afterwards a few of the screws on the wheel were machined down...from the pictures below, will the screws that were machined down potentially cause any problems ? thanks for the help

 

Take a screw out and see how much of the head is left. If it's the 225 mm flywheel, the wear surface is still availible for replacement.

 

I don't have the wheel in my hands, I was making a post so i could be pretty sure that it was what I need before I buy

 

the wheel it self is a 225mm mazdacomp/mazdaspeed light weight (nine pounds) aluminum flywheel made for 83-85 12a motors

 

Price, and does it come with the counterweight?

In all honesty, I have never had my grubbly little hands on a light fly. I don't know if or how much the can be turned. I thought the screws were supposed to be recessed a bit though. If the wear disc is too thin, it will not last long due to heat warpage. If the price is cheap enough, buy a new wear plate and screws.

 

no counter weight or hardwear to attach the clutch, and I would rather keep the price between me and the seller but lets say 2-3 range

 

Hmmm, a new one goes for how much, you need a counterweight, the wear surface may be thin and you need the blocks and bolts for the pp. idk

 

what is the peice that has all the screws everywhere called ?

-also is that the peice that I would be worried did not have much life left ?

 

Friction plate, 79 bucks at RB. Don't know if it the same disc as the Mazdacomp one or not. RB sells a new aluminumm one, with counter weight for 455. I personally would not pay more the 150-200, shipped if it needs a counterweight and friction disc. I may be stepping on someones toes, but then this is the 1st gen tightass section.

I don't know how much the Mazdacomp flywheel is, it may be worth what you are paying. I would replace the disc before installing the fly, but then I'm not too fond of dropping trannys either. If the friction disc fails, you may need to replace the clutch disc too.

 

+1

If the fricton plate is too thin, it *could* fail, destroying the trans.

 

Well if you where to copare it to the RB flywheel hich is 12lbs vs 9lbs. The Rb Aluminum Flywheel new come with the counter weight and is only $455. Replacement friction plates are $70

As for the one you want to buy I think the price is a little high especially if you have to buy a new friction plate and the right counter weight depending on who you get it from $40-60 depending on who you buy it from.

Its up to you but find out how much a replacement cost from Mazdacomp first.

 

RB flywheels are made by centerforce IIRC. So I recommend buying it from centerforce directly...Im sure it will be cheaper than RB

 

just to clarify what the red arrow is pointing to is the friction plate/disc...

 

Yes, it is held on by the screws. Go to RBs site, it has a pic of thier replacement disc.

 

cool it has a disk to replace i just got myn turned
how much is it what are the major advanages with a light flywheel

 

Good job! How come I can never think of these questions until AFTER I buy something important or expensive???

Correct me if Im wrong, but isnt the life expectancy of an aluminum flywheel much less than the stock ones? Just wondering if it would need frequent maintnence? Also wouldnt it be a bad combination for a racing clutch, like a 6 puck? Just things to consider

Does anyone know just how much quicker these lightened flywheels make the car?

 

An aluminum flywheel can last as long as a stock one, if it has the replaceable wear disc and is not grossly overheated. Puck, or brass button clutch discs are hard on flywheels. In this case, and aluminum one could easily outlast the stock because of the friction disc.

 

For aluminum flywheels, particulary the 215 mm, use carbon-kevlar linings as it will not destroy the friction plate and it last longer than the street/strip clutch.

Aluminum flywheel will allow the engine to rev fast but on a stop and go traffic, it can be a bitch. Once the RPM drops below 1K, you will need to downshift.

 

tell me what your opinions are on the pricce, I'm wondering if I plan on getting myself this far into the money if I should even take a chance on buying a used flywheel so I priced my options out

used alum. flywheel 250$ from fourm member
used countter weight 20-50$ from forum member
new flywheel hardwear from mazdatrix.com 42$
posibility of needing a new friction plate 80$
total 400 ish

If bought new on the mazdatrix site the alum. flywheel kit sells for 455$ and includes flywheel/counter weight/hardwear/brand new friction plate

Not going this route but just for options, If a person was to buy this indivdually (meaning NOT in a kit lol) from mazdatrix it would cost
New alum flywheel 370
New counter weight 152
hardwear 42
total 544, but the person would have new everything...

 

anothr question
would I need the rear or front counterweight of a auto tranny, or both ?

 

Just the rear counterweight (for whatever year enegine, I guess 83-85 in your case). I think I would see if the seller would go a bit lower in price and then get the new harware, friction plate, etc. It would suck to destroy the clutch not to mention the work involved replacing it just because the friction plate was bad.

A few things, though. I didn't look at the Mazdatrix, but make sure their friction plate will work with the flywheel the member is selling. I am sure the one at Mazdatrix is RB. Also do as Wacky said and see if you can go direct to the manufacturer to get cheaper.

I think if it were me, I would go new if the seller doesn't want to lower the price. There isn't much difference in price, and you know everything is new and will work together.

 

thanks addict thats some helpful nfo

 

Save your $$$ and get an 81-82 215mm flywheel only weighs 23 lbs. There was a thread on using 81-82 on 83-85 motors.

 

the stock one weighs 23 pounds so what would be the point of that ?

the alum. one weighs nine pounds (around 13 with the counter weight) plus I think that it will make my car feel lesss like a slug all the time and have a little pep behind it in second and third

 

Dude, dig this up. I missed it and it should probably be archived.
