DrF,
Personally, I would retain the DMF, replace the pressure plate with a Sachs 999 and put in a new GT2 unsprung clutch disc. If you plan on 24/18G's then I would modify the pressure plate for additional clamp force before installation and use a Sachs Motorsports unsprung GT2 style, high friction disc.

Good pick.. but the dual mass flywheel has hp/ torque limits but no doubt the smoothest the gt2 unsprung disc is very good on the trans and the dmf takes up the chatter.. I ran that for a while.

Tim,
Agreed on the HP/Tq limits, but for K24/18G it's fine. I run this combination with the upgraded clamp force and the high friction disc on a 24/18G car with full supporting mods and 1.32 bar of boost. Over 20,000 miles on the components and it's rock solid. I also have the GT2 non-assist and love it.
At first, I did not upgrade the clamp force and it started slippng after 6 months with 18G's. After the PP upgrade and the disc upgrade - no problems whatsoever. Great clutch set-up!

No, below is the non-assist GT2 conversion kit. It is a separate group of items. Your description of the assisted clutch is the reason this kit exists. It puts the "feel" back into the mix and every launch is predictable with precise control. There are several really good mods for the 996TT and this is definetely one of them. We have sold several of these kits and our customers have been extremely pleased with the change. It does increase the pedal effort, but you get used to it quickly.

The labor prices you were quoted are dealer prices. A shop in Austin quoted me ~$600 for clutch install and ~$1700 for parts. I do not think anyone in Texas can beat that price. They are pretty familiar with the car and do this type of work on a regular basis. They also offer a $3000 exhaust + tune package installed.
Since there is a long wait to get the car into the indy shop (end of october) I'm going to have the dealer take a look first. I also told him about 2nd-gear popout and he said depending on what is causing it, it will be CPO covered.
He did quote me for replacing the clutch at $5,000. $1700 parts and $3300 labor. Is that reasonable? If you can get the flash and exhaust for the same price how are you doing that?
In terms of exhausts, I'd like a bit more aggressive sound but not too loud. I want to hear it when I WOT, but I don't want to hear it when cruising. Suggestions?

The dealer quoted me for a stock clutch; however, he said he would be happy to put whatever clutch I wanted into the car. I'm not yet sure if that means he would order it or I would buy it and bring it in. I would guess still $3300 labor plus the cost of the parts. I was happily surprised that it wouldn't affect the CPO..
I'd offer the dealer the clutch job- at their silly rates- if they will take care of the 2nd gear issue under the CPO. Remember, it's no skin off their nose, since PCNA foots the bill on the 2nd gear. Indeed, they will probably 'double dip' and nail you for the full labor of a clutch job, AND get pcna the full cost of the tranny removal.
But do not agree to a "we'll see what it looks like when we get it out" deal, since that will be "sorry, you car is in pieces and PCNA wont cover it and it is $8000 more" deal

- You can get a lightweight dual mass flywheel from Aasco that alleviates using a longer eared release bearing...Quite a few of us have had them snap off due to the thinner lightweight flywheel. Also, some tuners will sell you the single mass lwfw but not send you or sell you a patch for the idle issue...unless you buy a complete tune from them. Remember, the single mass lwfw is prone to stalling issues. It will happen, no way around it unless you get a patch [I'd bet EPL would hook you up with something, but I also think they recommend against the single mass due to the above release bearing issues...but call them and ask...that way you hear from the source instead of reading about it from me...as I am not positive!]
-Strongly consider doing the GT2 modification when you do the clutch. Probably the single biggest issues people have with these cars that is clutch related involves the master and or slave cylinder. The GT2 mod fixes all those annoying problems.
Good luck and enjoy!

To the OP, good luck with your new clutch, definitely upgrade it. No point in getting another stock one if it is just going to keep slipping as already stated by the experts above.

I have the same car as you do but a cab. Purchased new and flashed at 4800 miles. Clutch could not hold the TQ. Purchased a carbonetics triple disk and LWFW and had dealership install at $2000 with a tranny oil change. No stock replacement will hold so if you get a CPO replacement it will also slip.

In an other thread you state that a clutch job in a 996 turbo takes 3 hours. Why would you pay $2000 in labor for it then? The dealers in New York are $130 per hour are the CA dealers charge 666.67 an hour

My guess would be in the other quote he is talking about an indie shop, who uses the simple way to do the clutch. First line of new clutch in the dealer book says "REMOVE MOTOR FROM CAR."

Whatever you do, DO NOT mention a flash to the dealer....

It sounds like clutch and exhaust will be done shortly. I better invest in a Passport 9500ci as well... I'm getting quoted $2500 installed for it. Reasonable?
