993 c2 Clutch/flywheel DYI guide ?

[wesleyc]

I will be replacing my clutch and flywheel and would like to know the best instruction manual or book to buy ? I have the performance handbook and 993 essential companion. Surprisingly neither show much on clutch replacement ? Any ideas out there ?

These two discussions on RennList might be helpful. Seems to be a relatively inexpensive alternative to the factory manual.

Thank you.

For the record, there's nothing special about the "Essential Companion." That book was probably useful several years ago, but when you take out all of the self congratulatory verbiage and the essentially useless photo section, there's very little in the book that can't be found online or in an owner's manual.

I agree TMc concerning the E Companion. How can a 10lbs book on the 993 not have a clutch replacement section ? Oh well... A mech has offered to do the CL/flywheel change for $1500 in labor. But warned me not to get a LWF if it was my everyday car due to heavy clutch and stalling. I would get a Steve Wong chip for the stalling but stiff clutch might be tiresome in town... Don't know which flywheel to get ? This is as bad as the wife picking out shoes ?! Thanks. John

John,

Did the current clutch suit your needs when it was working well? If so, is there a reason to change to another configuration?

When I had to replace my clutch, I said something to my shop about going to a LWF and they asked me how that would enhance my driving experience (Which is mainly rural roads and no track time).

I had to admit that I could not cite a valid reason for changing to the LWF. I had read a bunch of "stuff" online but honestly had been completely happy with how my clutch worked until it started slipping. Their response was, "Then why change it to something different?"

I stuck with the stock equipment and not once have I found myself thinking, "I wish I had a LWF!"

I realize there are valid reasons for going to that configuration, but just because someone on Pelican or RennList did it isn't one of them.

Just my opinion...

[wesleyc]

Thanks for your input TMc. DM flywheel is sounding like the way to go on a 95 grocery getter. The shop won't give a LWF a guarantee assuming it'll be on the track I guess. But it gives the factory setup 2 years and lifetime on labor. Guess I could still chip it to give the car a little extra punch which is really what I'm wanting anyway. Thanks. John

There is a good write up on pcar workshop I think. I used several online resources and the factory manual when I did mine. Its pretty easy to do really. The factory manual was very helpful since it provided the torque spec and the gap spec for the flywheel position sensor.

I have the lwf and rs clutch. I daily drive and track the car on de days. I have no issue with the clutch being heavy or stalling. I hear the stalling is mainly a 1995my issue though. The few people who have driven my car have had no complaints about a heavy clutch or trouble with drivability.

[wesleyc]

Thanks for input jhg. Is your car a 95 and if so did you chip it after the lwf @ clutch ? Just curious. John

[jhg41977]

I have a 1996, so no stalling issues from the computer. Several guys on rennlist have 95s with a lwf. I cannot say how much difference it made. I bought mine with a bad clutch, so it was hard to compare. The instructors who have driven the car liked how it felt, several had 993s of their own.

[jhg41977]

Try posting a request to drive a pelican or rennlisters car nearby if they have a lwf. I bet most would be willing to go for a ride with you if in their area. Im in NH and my car is apart right now

[wesleyc]

Thanks Jim. I'm surrounded by lifted 4x4 trucks in my rural oklahoma town so it might be tough finding a 993 with a lwf to drive within a 100 miles or so. Good idea though ! Hope your car gets back together ok. John

I've already planned on doing the same, because I know it works.

Ever notice that when an OEM part fails, so many think an aftermarket part is the only solution to the problem. The fact that the OEM part lasted the life of their car so far, never even enters their mind.

Hello wesleyc, yes the new 993 manual has a good section covering the replacement of the clutch mechanical and hydraulic components. Our hosts here at Pelican Parts have it in stock at this link: Porsche 911 Books & Technical Documentation - Page 1

[wesleyc]

Thanks for response. I have ordered the Bentley manual and a Steve Wong chip for DMFlywheel... This porsche habit sure can get expensive !

P Fix It | Porsche 964 | Repair & Maintenance Videos covers this in chapter 9, but it's for 964.

Apparently you have a 95, which experienced stalling issues with the LWF. My car is a 98 and it is fitted with the LWF and RS clutch. The LWF makes a really noticeable and nice impact on the car's performance. And, I do not experience the stalling that was problematic with some 95 993's.

I believe that Steve Weiner has developed a LWF for the 95 that should work well while eliminating the stalling issue. As I recall, the pricing for his LWF was not exorbitant. His flywheel is slightly heavier than the normal LWF, carrying just enough extra mass to maintain the inertia flywheel effect that is the main function of a flywheel. The LWF eliminates the problematic dual mass flywheels that were installed in order to "isolate" the passenger compartment from mechanical noise.

Give Steve a call. He knows more about this issue that most of us combined.

[wesleyc]

Thanks for info. I will have to contact Steve weiner concerning this. I'm still limping along with my clutch for now.
