Ok check it out...Shouldn't the threads in the stock flywheel and in a correct aftermarket flywheel be the same? I mean the threads where the bolts go to hold the PP on to it? Becausemy stock flywheel has 8M fine threads but the aftermarket one has 8M coarse threads. So anyway I had bought this lightweight FW, ACT CP and ACT PP from a dude on the forum he said it was off his 89 NA and he was selling it with only 5K miles on it because he had more mods and was swapping to a turbo tranny and stuff, so I buy the whole setup for 300 bux and I bring it to a shop to have them install it all...well the shop is kind enough to THROW AWAY my original FW, CP, and PP and all the needed bolts and just try to use the stuff that the guy sold me. So anyway they put in his setup and it won't come out of gear, they charge me 300 to do that and tell me there is nothing they can do for me to try and get my original parts back. Pissed off I tow the car to a speed shop that has lots of time under RX-7's and they try to reinstall the parts and they too can't get it to come out od gear and charge me 160 bux. Pissed off again I tow it home and try to do it myselfand I get the same results so I figure the dude might have sent me the wrong parts and I try to contact him but he never answered a single message or email. So I go and get another stock flywheel and try to use his clutch disc and PP, but lo-and-behold the threads are different, like I described before, so I figure the entire setup that this dude sold me was bogus, since the flywheels are threaded differently, except the sizes are perfect the diameter of the FW and the clutch plate and the PP are all exact, the spline shaft diameter of the clkutch disc is exact it all seems right but it just won't work at all. ANd on top of that, the guy had said that the clutch was ACT brand but it is actually a Daikin clutch, so he lied to me from the beginning about it. I'm pissed and thinking that I have been shafted out of about 800 bux. hell for that price I could have gotten an entire lightweight setup brand ****** new and installed. So anyway, those threads should be the same if the two flywheels are infact for teh same car right? WTF

Doesn't sound like you got ripped off by the seller. Sounds like you got ripped off by the installer.

ACT brand might have parts made by Daikin, maybe/maybe not. I had a steel lw flywheel for my TII, the threads were the same, but I don't think that is a big deal in your case. If the flywheel even bolted up to the car it is at least for a rotary. You really need to show some pics so we can see what you've got.

The shop should have NEVER thrown away your stock parts, especially before they got the new setup working.

right I know they should not have thrown away my parts, but my point is this... if he infact sold me the flywheel he said he was selling me, then the threads in it would be the same as a stock flywheel...since the two flywheels should be IDENTICAL except for the weight. Maybe this will make it easier to understand......If I only bought the flywheel from him and I tried to use a stock clutch and PP I would not be able to attach the PP to the flywheel with the original hardware, which is wrong

My Junx

so now to see if anythig will work I have to go try to get a set of original bolts to attach my PP to the new stock flywheel and maybe it will work after that, if infact the clutch and PP that he sold me are the correct ones. If they do work after I get a set of original bolts, I will know that he sold me an incorrect flywheel.

Ok first off, ACT sells ACT ****. I just bought a 4puck with an HD pressure plate and it has ACT laser engraved in the steel.

Second, Go back and bitch the people out that threw your stuff away, then tell them to give you a prorated amount of money back for the stock flywheel that they threw away. About the equivelent of picking up one at a junkyard.

Take that money and your lightend flywheel to a machine shop and get them to re-tap the flywheel to the right thread.

That's what I would do...

IMO they can choose one of the following:
1) Make your current system work.
2) Convert your car back to the condition it was when you gave it to them, and give you back the "ACT" parts.
3) Pay for another shop to fix your car.

Charging you $300 for a clutch job that will not come out of gear is BS. I think you have a very good case to sue them.

That's sorta true -- but I could also see how they could duck right out of any legal liability by telling the judge that the parts the guy brought it for them to install had problems before they touched it. Since it is not Mazda OEM I can't see how a judge would really say, "Oh, well the *Used-Aftermarket* parts that you brought them were not up to spec on the job." It just seems to sketchy to really bring up in court, unless it was clear cut, i.e. "I payed these guys 300 dollars to get my car running again and they fucked it up".

Now, throwing away his old parts... THAT'S where the lawsuit would be. Those parts were his, and unless he requested that they throw them away, (every time i've ever been in a shop where i've had performace parts replace stock parts... Even parts that were worn out and no longer usable... they've asked me if I wanted to keep them) those parts are still his, and he should be paid every penny to be reimbursed for them.

yeah I know it was very fuct up of them to toss my original ****, but I really don't feel like ******* with it all. I got the right bolts from home depot to put the daikin clutch and act PP onto my stock flywheel. I also got the tranny back in. Tomorrow I'll get the drive shaft, starter and shift lever back in and see if this **** works now. Anyway I'll update tomorrow.

Not sure about the law in your state, but in California, your old parts are yours, and have to be available to you once they've been removed from your car. So you would be able to sue them for the value of your used clutch, but not much else.

Kinda sidetracking his topic but a lightweight flywheel wont do much for performance will it? I mean for the money... I think I can pick up a stock one for like 75 bucks while a lw steel one that isnt much lighter cost about $400... do you guys think that lil 2-5hp is worth $325 or not?

Last time I checked, the main purpose of a lightweight flywheel is not to increase the horsepower, but to increase the speed at which the engine can get the engine to the appropriate speed to apply the current amount of horsepower.

Lighter Flywheel=Quicker throttle response
