First off, why do you think you need a new flywheel? Second, you're looking at dropping a couple hundred or so, Mazda might still have some, if you really feel brave, find your engine at a junkyard and pull the flywheel and counterweight off that.

I know there are aftermarket lightweight flywheels that are around $400 from Mazdatrix and such. Maybe RockAuto.com has it in their part fiche?

what year is your 7? flywheels were weighted differently for different years based on rotor weight... posting a want to buy ad here on the forum in the 1st gen for sale/wanted section for the appropriate flywheel will be the cheapest alternative. if you are wanting to buy one new i can get you the part number and check availability.

the reason i thought i need a flywheel was because one of my friends that knows a quiet a bit about rx7s says that when you go drifting, it could crack it, and i went drifting. but i feel stupid for thinkin that because im pretty sure its the throw out bearing. thanks thou

Be pretty hard to crack our flywheels, those things are thick. They usually either stay in one
piece or explode in a billion when you over rev.

Don't listen to your friend anymore

I've never heard of one disintegrating although I'm sure it could be done but you
would probably grenade a stock engine before you could do it.

I don't know who is a bigger idiot, your friend, or you for having him as a friend and listening to him.

I bet he also told you that you can port and polish your head by sucking sand in through your intake

You don't just "crack" a flywheel. The only way that physical damage like that happens is with a sustained over-rev situation, where the Centripetal Force exceeds the stress the flywheel is designed to handle, an inclusion (stress riser) is found, a fracture propagates, and your flywheel literally disintegrates, sending large, high-energy chunks of cast iron (or aluminum/chromoly) in tangential trajectories. These pieces will penetrate basically anything in their way, wreaking havoc on whatever they come near. The pieces will embed themselves in the pavement, shoot through your floorboards, and have been known to break/shatter ankles that get in their way.

What symptoms are you experiencing?

Also, stay away from the drift scene if you want any respect around here...

So wait... your friend told you, or implied that, only drifting could crack or destroy a flywheel. So over revving on a road course won't do anything? Neat. I need friends like yours.

There's nothing wrong with drifting. It's fun and is also a great way to learn car control at or over the limit.

Drifting was invented by the asian tire manufacturers to sell tires. Plain and simple

Drifiting to road racing is like comparing figure skating to speed skating.

Depends on what you mean by "drifting" I always just looked at it as an extension of racing. We all do powerslides and "drifts" in turns occasionally and its a good technique to know. Drifting is just the exaggeration of that. Same as how Drag Racing is pretty much the same as launching on a straight, just more hilly billy loved. Just kiddin' on that last part.

That's what you get for studying mechanical engineering for 3.5 years before switching majors.

Drifting is a subjective competition. I equate it to gasoline-fueled ballet on tires. You "win" because you can achieve a technically sound "drift". The same as if you were a figure skater and completed a jump in a technically sound way. It is more of an art form than a motorsport.

The clutch disc will let loose long before a flywheel does. Fwiw, most disc have a 10k rpm limit.

if ur still lookin for a flywheel, ive never had any problems with racing beat

Agreed. There is a video floating around the interwebs (can't find it at the moment) of a camaro doing a burnout, w/o a scatter shield, and the clutch explodes. Parts of the disc end up in the pavement and sticking out of the dashboard.
