GT2 slave conversion, big difference
Hey all,
I am a fairly new owner of a 2001, for about 4 months. I loved everything about the car when I bought it, except for the clutch. When the car was in the shop to have the coolant pipes pinned, I decided to do the slave conversion at the save time.
What a big difference, night and day. I used to dread coming to a stop light, especially if it was on an incline. Now, it is no big deal. The engagement point is the same every time and I can build my muscle memory to the clutch's engagement point. I can totally finesse the clutch now instead of relying on a lot of throttle in order not to kill the engine.
The pedal pressure is heavier now, but it is not that bad at all. I had to drive it in one of the worst traffic in the country the other day (880 in the bay area) and it was no problem. This is how Porsche should have build it in factory instead of the assisted BS. If you are on the fence before and you like manual trans and don't have any sort of knee issue, get off the fence and do it. I was and still am amazed by how much better it is now. One of the best mods, period.
Now the car is truly enjoyable. It has got power (500 whp), handling (pss9) and sweet shifting (gt2 slave and GT3 shifter). Time to go on some drives!

Glad you made the mod and enjoying it!
Though I'd like to offer a alternate success story. Not suggesting it's a better or worse choice. Just another option.
My slave failed leaving a nice puddle of pentosin on the ground. I gave the GT2 slave a lot of thought. In the end, I decided to keep the stock boosted setup and replaced the slave and accumulator. And upgraded to a '999 764' pressure plate because my stock clutch was slipping with my upgraded turbo's.
Couldn't be happier with my choice. The clutch weight is just great even with the motorsports heavy pressure plate. And clutch engagement/pickup is perfect as well. You wouldn't be able to tell it's boosted if you didn't know it. Not the sketchy engagement point issue I was experiencing near the time the slave was failing.
That said, if the assisted setup is not working for you, it may just be that the components are failing and need to be replaced.
Or you can opt for the GT2 setup which I'm sure is great as well.

I'm still adjusting to my new setup but hope to have the same outcome once I get more accustomed to it.

The car came with LWFW and clutch upgrade that was done only 5k miles ago. I believe it was Sachs stage 2.5 disk.

My C4S has a different system than the turbo. Much harder to push in the clutch pedal. Wonder if that is a viable swap. Gotta believe the cost would be way less than GT2 parts.

always find it weird driving a 996TT with stock clutch hydraulics, GT2 clutch gives the driver wayyy more 'information' but is heavier(which I also like, some will/some won't)

I cannot tell you the difference because my accumulator was still good. However, I think having a "proper" clutch fitting for a sports car should not harm the resale. Anyone interested in the car should care about how the car drives.

the gt2 clutch conv feels just like a 993 or a gt3 clutch.. or any "normal" clutch lol. it has a more precise engagement and i think eliminating the hyd assist will indeed affect the possible resale. i wouldn't do it unless the car had no chance of ever being really "stock" again. in which case it must be great mod. gee, why haven't i done it yet!? in the meantime i just have my accumulator as a normal maint item. i swear you can replace one and it can go bad within a cpl months! by "bad" i mean occasional hard pedal at startup. beyond that, i guess i'm just used to its inconsistency which is consistent lol
'm sure i'd like it the gt2 mod. i applaud those who have completed it.

I don't have a problem with the hyd assisted. Never noticed any problems with engagement. It did have issues when the slave went out and the engagement would vary, ever since replacing the slave its been great and predictable.

When the accumulator went out the clutch was still easy to operate just the initial push when I went to start the engine required more effort. Once the engine was running though the clutch was boosted. I do not recall any untoward behavior from the clutch when slave cylinder when it went bad -- started leaking fluid -- but I didn't drive the car much when the slave was diagnosed.
