I'm piling up the last few detail parts before I pull my Miata apart to put the turbo on, and I had a few questions about clutches before I buy one. How much torque is an Exedy 1.8L stock replacement good for? What are you guys using? I'm running a DSM T25 for the time being (probably all I'll ever run), and I don't need a nasty, grabby pain in the ***. I also don't need to spend a fortune on my daily car, and the Exedy can be bought on Ebay from Gripforce with a Fidanza flywheel for ~$450 shipped. If the stock replacement isn't going to be enough, I guess I'll buy a Spec stage 1, as I have a hookup on Spec, and they're based in Birmingham, about 2 hours away, and they will replace a clutch for free at the drop of a hat.

If I do this, where should I get a flywheel? The eBay Honda flywheels are <$100, but the Miata equivalents are closer to $200. Is there another option, or am I stuck? Is there anybody else who sells a clutch/ flywheel combo that will hold the torque/ take the abuse for reasonable money?

Skip the flywheel and get an ACT HD... best $305 you ever spent: http://www.carolinaclutch.com/ShowItem/101367.aspx

ACT 1.8 size

If you whine about the cost of parts vs Honda parts again we'll ban you. One of the best attributes of the higher cost of Mazda parts is it keeps bullshit ricers away.

Calm yourself. The Miata is a sports car, the Civic is an appliance. And we seem to have plenty of ricers in Miata land even with higher parts costs. Why ACT, and why not use a light flywheel? If I go to a 1.8 clutch, I've got to buy a flywheel no matter what, why not buy one with benefits?

I've got one and to do it over again I wouldn't. The money for the flywheel is better spent elsewhere. Like on coke and ******.

Blow me. Do a search. Plenty of clutch related threads here to pick from. Show me you're worthwhile to help before getting uppity.

I spent months agonizing about what clutch to get- I wanted a good price on a part I could rely on.

I ended up going with Clutchnet. Then sent it back because seemingly half the people who got in on the group buy were having problems.

Spent another few weeks agonizing about what clutch to get. Went with an ACT XTSS and this critter can handle substantially more torque than I ever plan on making. The only downside is that it wasn't cheap.

Logic here is I want to do this job exactly once. I don't mind wrenching on cars but I'd much rather be driving mine than replacing its clutch.

What exactly is your damage? I went out of my way to make helpful suggestions in your suspension thread. Why would you bother going to the trouble of typing up a response like this? For that matter, why would you try to say that Miata owners take pride in paying extra for parts? Thats ridiculous on a number of levels. Not only is there no shortage of ricer Miata owners, but cost of parts has NEVER turned them away from a vehicle. You sound like you've been on M.net too much today.

You must be new here.

You absolutely get what you pay for, but the Spec and Exedy stuff is top notch, and it can be found for reasonable money. I guess what I should have asked is, is a 1.8 stock replacement enough for the (maybe) 200hp the car will be capable of, or do I need more.

Some stuff one can find here and elsewhere:

First, let's establish the amount of torque one can expect:
https://www.miataturbo.net/forum/showthread.php?t=15245
I think it is reasonable to assume this represents the upper limit of what kind of torque output you can expect from your motor.

Now that you have read the thread above (right?) and you have an idea what kind of torque range you can expect, then you can go here, for example, and pick a clutch:
http://www.advancedclutch.com/135622...1.8L_N_FI.html

As Ben said there are a LOT of clutch threads here. I even posted in one of them. Give them a read. Then you can come back here and tell me to calm down too. I, however, will pass on the blow job.

Chris, nice job on the intro thread:
https://www.miataturbo.net/forum/showthread.php?t=22600

As I said, get the ACT HD. Even though you you have the stench of NOOB (no location in your profile and nothing in your sig) I deduced you currently have a 1.6 flywheel installed and if you bought the 1.6 ACT HD clutch you wouldn't need a new flywheel. That clutch will carry you safely to 200whp. If you're worried, put out the word you're looking for a 1.8 flywheel and somebody will probably send you one for shipping... or maybe somebody local to you has a stack of them at home you could just have one. Then the 1.8 ACT HD is only a little more. The Spec Stg1 is not common here... you'll be a guinea-pig. Lots of guys use Exedy.

The lightened flywheel debate is a common one. There isn't a large number of guys who think the cost is worth it. Many who buy one swap it back out. Those who daily drive one say it sucks in traffic. Making a stock flywheel lighter is a $50 proposition and allows you several attempts to get the right balance. Before you spend the money, you should actually drive a Miata with one installed to see if you're going to like it. I have done all the homework and weighed all the pro's/con's and I'd rather spend the money a new set of tires.

PS: This forum is in no way touchy-feely politically correct and there is a very high learning curve for NOOBS. You don't appear to be a Miata NOOB, but you're new here. Ben obviously wasn't serious about banning, he was trying to make a point. We often get Honda guys wondering why things cost so much... on the same hand, guys who show up who also own BMW's rave that **** is so cheap. It's not a fair comparison, we hear it all the time, you know now.

And for the record, THERE IS AN EXTREME SHORTAGE OF RICER MIATA OWNERS ON THIS FORUM. We keep it that way. Trust me you will like it that way. Your "m.net" comment would lend me to believe you already know this, so I don't understand why you made it. Life goes on. Take the ribbing in stride... talking **** only shows you have no sense of humor.

I think you misunderstand. Allow me to hit the search button for you

And then you can search for threads by braineack and newbsauce on why you should never get a clutchnet clutch. I believe both are using ACT now.

And then you can search for samnavy's thread on why you should not get a spec clutch. I think he's still using the spec clutch, but is keeping his boost controlled to prevent slipping.

And then you can read m2cupcar's thread about the 3 cluthes he broke before going with ACT. Admittingly I hate his exact clutch, but considering he drives the car under 1k miles per year it's not that bad. Maybe if he had a more pleasant clutch he'd drive it more though.

So after you do a bunch of reasearch, you'll come to find that you want an ACT in 1.8 size. You can also find tons of info on stock, lightened stock, and aluminum flywheels. My preference is lightened stock.

Frankly the amount of data here on driveline and drivetrain is staggering if you search. Unfortunately the amount of info on other things as suspension is pitiful.

The folks here take pride in DIY and finding the best value for the money. We don't over pay. And we're very glad that there is little to no ricer market, very few "JDM" crap parts, and that we don't have the crime problems associated with the "other" crowd. I've never heard of someone carjacking a miata, though it would be easy to be victimized in this car. I hear almost daily of civics being stolen or carjacked. In fact, it hardly ever makes the tv news it's such a common occurance; there's no shock value there anymore. You may think I'm overpaying for parts, however I'm not worrying if my car will be stolen or stripped if left unattended and I have low insurance premiums.

Thank you for the effort, dude. Like I said before, I asked the wrong question. Now I've gotten the answer, anyway.

Purely for clarification: I've heard of people lightening stock Miata flywheels, but I question the safety of it. Has anybody ever blown up a lightened stock flywheel? I've actually seen a lightened Mustang flywheel explode, and it wasn't pretty. Pure luck was the only reason the guy ended up with scars, not stumps. And the car was a write off. Trans tunnel blown full of holes, interior shredded, windshield broken. Basically everything in a disc around the bell housing got beat to pieces.

FWIW, I actually did search for 'clutch' and after about 5 pages, gave up on finding the answer I wanted. Noobish of me, I suppose, but lacking a direct answer, I thought I'd ask a direct question.

edit: and I just realized how fukcing hypernUUb that last sentence sounded. ****. *sigh*

The part of the flywheel you shave is a large "ring" out near the very edge. I believe the only purpose of the ring is exist as weight and it has no structural benefit. I've never heard of a flywheel failure in a Miata.

Ben

iTrader: (33)

I guess anything is possible, but I've never heard of it happening. Like sam said (and when you see the fw for yourself it will be uber-apparant), the area that you shave off the fw is a ballast ring.

I like having some weight to the fw for smoother idle recovery (important on a street car, not so much on track car) and some margin of oil pump safety.

That's all that gets removed from the bumpkin-fied Mustang flywheels. I've seen the flywheels, and I know exactly what you're talking about, in fact, I (reluctantly) gave my blessing on the whole affair when the guy said he wanted to do it. I had heard of modified stock flywheels letting go, but it looked safe. First time he took it to the track, it came to pieces at 5500 rpm in the burnout box.
