Default Permanent fix for clutch salve and accumulator

As I searched the archives, I only found that upgrading to a 996 part is popular and replacing the slave to a NA part. Is there a kit with part numbers to do a GT2 clutch like the 996?

I don't believe there is a kit.

The 996 part number just superceded the 993 part. What changes were made, who knows?

I really wish you could have had a chance to drive my car. The difference was astounding.

I think if you go NA style, you may just need to cap a line and install the different slave.

Its shockingly cheaper.

I am going to take to CIM and have Irek take care of it. Dan Jacobs never got back to me with a quote so I am having Irek do all the work.

fair enough.

Like I said before, if you want to buy the distributor cap and rotor and fuel filter, I'd be happy to do that for you, along with an oil change if you need it.

Definitely have Irek check the clutch though.

I'd be a bit worried about losing the power assist on a turbo clutch, let alone if its been upgraded to one with even more clamping force. When I drove a Ruf BTR (Ruf single-turbo application on a NA 993) I found the clutch to be stiff enough to be unpleasant. Its NOT the same as the clutch on a stock NA 993. When more clamping force is added to handle the torque of the turbo, the clutch pedal gets very stiff. I'm sure Porsche agonized over this before finally coming up with the crazy complex power system on the 993TT clutches.

My clutch is not assisted and the slave/accumulator have been removed. Now, the problem is, no one knows what was put in (about 6k miles ago). The service records i have just say "customer provided materials"

During my PPI, they told me the only way to know what was inside was to open it up, and at that point i should replace the clutch and put in the accumulator/slave etc...

Well, i didn't do anything Its been almost 9 months and 3500 miles since I purchased the car, and I'm loving the clutch. The only other manual i had experience with was a 2008 C2, really smooth, but i seriously doubt it could handle the torque of the TT.

So, with that said it takes some getting used to, but in my opinion worth it... now if i only knew what was in there!

Mine is not assisted either and I like it a lot. Mine is also upgraded to handle 600+ HP. It is not too stiff and the consistency is excellent. I'm not sure the exact parts but it is whatever Kevin recommended so you can ask him.

Yeah, they pretty much screwed up

Mine too. Not an issue for me.

Meh, after years with a heavy Spec clutch in my mustang, I am enjoying the "all day comfort" of the hydraulically assisted clutch.

For those of us that have backdated the slave I'm curious what the "upgraded" slave cylinder is? The only one I can think of would be the 996 GT2. I think its a plastic body though where the current porsche/FTE offering is metal and has the boot over the rod. On first glance the regular 933 one seems to be a more robust version

I seem to replace my FTE slave every other year once they start to squeak. Gotta bleed the SRF once a year anyway so putting another $75 slave cylinder in there isn't really a big deal.

Thanks! I think I will drop him a line and get the parts. The kit gets dropped in once the clutch goes.

Anyone have also driven a GT3 with this setup and care to share as to which clutch is heavier? I have driven a 997.1 GT3RS Euro clubsport version and do not find the clutch difficult to handle.

It is a lot like the 997.1 GT3RS

If you backdate to a non-assisted setup, the pedal effort will assuredly not be as light as a 993NA. I have not experienced a 993TT backdated to a traditional slave cylinder, but I have several customer 996TTs with the GT2 backdate and upgraded pressure plates. A 996 GT2 slave cylinder itself should work, as the transmission bell housing/clutch release setup is the same. As for the hose to the slave cylinder, that also needs to change. At that point you can ditch the Pentosin and run brake fluid in the clutch hydraulic circuit, but some high pressure lines from the power steering pump will need to be plugged off or looped. Sounds like Kevin from UMW knows exactly what you need to get it done though.

Porsche still has not perfected the hydraulically assisted setup, we recently replaced an accumulator on a 15K mile '08 997TT.
