no, the ring gear in most cases when buying a flywheel is not on. It needs to be heated up and forced onto the flywheel then spot welded.

Kas

i know what you mean, however maybe i didnt explain well enough

rotarygod

No flywheel that I have ever seen or personally used has been that way. They are just simple bolt on pieces.

WTF no turbo

Yea i have mazdaspeed flywheel and mine just bolted.

Kas

some aftermarket flywheels that dont carry the cost of big brand names dont come with the ring grear attached so you can re-use your ld one..

for e.g:



I thought the mazdaspeed needed the ring gear added also such as this one above.

Broke_Apex_Seal, which couter weight did you use? The mazdaspeed one?

Kas

you can get the counter weight from mazda. make sure its the auto one.

rotarenvy

why is it the auto one?

davefzr

So which one sounds the best to you guys? The ACT, Mazdaspeed and I have also heard about JUN though I dont have much information on it...

Thankx!

Why would you use the auto counter weight on a 6-sp? Doesn't this throu the balance out?

Kas

yeah i know it sounds funny but its the one you need to make it balance. i dont know why either but i've used them in my s6 rx7.

or maybe this one..

To me the ACT seems like the way to go. Best bang for the buck.. 400 bucks that is over the MS...

MS flywheel = awesome!

Torque setting for the flywheell main nut is 361, as per the service manual; also requires some locktight...

davefzr

I decided to go with the MazdaSpeed flywheel for 525 from Trussville Mazda. Anyone know a better price before I purchase it?

Also.. what about the clutch? I am getting the flywheel done, do any of you think it would be a good performance investment?

Thankx!

How does a lighter flywheel affect engine braking? Does it make it brake faster (because the engine is able to decelerate quicker) or slower (because the engine is can't drag the wheels down as quickly)? Or neither? Or one of those two, but for a different reason?

Jason

Dont waste the money the the Mazdaspeed. That stuff is so overpriced. Get the ACT.

So guys.. which should I buy. The mazdaspeed flywheel or the ACT chromoly flywheel. It seems the mazdaspeed is 16 pounds with the counter weight and the act is 13.5 with the counter weight. Can anyone confirm this?

MrWigggles

The ACT makes more sense but I have had transimission problems (shifting into sixth gear).

The next time I have problems I don't want them blaming it on the flywheel if it isn't Mazdaspeed.

Otherwise I would say ACT in a NY minute.

Just wonderin how much harder it would be to drive with the ACT flywheel as its a few pounds lighter than the Mazdaspeed one (which is slightly lighter than stock, I believe). Can anyone help enlighten (no pun intended...)?

Japan8

My concerns are like Mr. Wiggles. especially for such an internal component... is it really going to be ok to go with ACT instead of Mazdaspeed. Even if the ACT flywheel/clutch isn't the cause, I'd hate to go through the paces with the dealer because I had ACt dropped in instead of Mazdaspeed. You experienced and knowledgable people (ehem... rotarygod, jason, mazdamaniac...) convince us that ACT is the way to go even when thinking about possible warranty issues...

mazdaexe

Jason,

Will you have the ACT flywheel and counterweight anytime soon?

Thanx

Jason

I have both in stock now. Give me a call if you need one.

Thanks
Jason

ACT=No Warranty... Also the MS is much lighter than stock... Engine brakes faster with light flywheel...

davefzr

5 pounds lighter... I think the ACT pushes the lightness to the extreme, same with mazda trix, at the expense of drivability.
