Interesting turn of events on my '95. My local P-Car mechanic (The best 993 maintenance guy in town) will not install anything but a DMF & clutch setup on my car. He says he has had too many customer complaints about stalling, and ends up pulling them out. I am going with the MWF from Andial (through Steve W), and he is going to do the install work. The bad news is I have to wait a while for him to get to it.

Does anyone have the part number for the kit? Just curious, I always thought that you had to buy the component individually. I am likely to do the top end of my 993 this wall and a clutch might be in the works.

Kevin, can you fill us in what are the options for the pressure plates?

Cheers,

Mike

Mike;

With regards to OEM plates, the options are very simple. The N/A engines do not make enough torque to step up to the "New" power kit or RACE GT2 pressure plate. The RS plate will work, or you can step up to the normal GT2 pressure plate. I'd step up to the GT2 (non- race unit) plate if I was doing any DE events.

As far as the DMF vs a lightweight unit. People just can't drive or won't use a clutch correctly. The 930's or 965 don't have them, the 3.2 Carrera's don't have them. The 3.6 has more torque to pull the car out of the hole. There is no idle issue from '95 up.. Unless, you need a tune-up and your plug wires are shot.. Dropping 28lbs from your rotating assy saves there wear and tear on your bearings and thrust components.

There is no part # for the "kit" since the kits are just a bundle of parts selected by a vendor & sold together to make life simpler for consumers. Therefore, kit components may vary between vendors making it important to confirm which parts are included. FWIW, I purchased mine from Viper Bob who also gratuitously gave my shop phone advice during installation.

There are stalling/idle issues with LWF on the '95. They can be overcome with ISV & driving style adjustments most of the time. '96 & up ODB II cars have no issues with the LWF setup.

I can make a OBD2 car stall at idle, including a 996GT2 with the lightweight package.. It's really up to the driver.. The '95 has the software to compensate unlike the 964's..

Kevin,
Do you know what the clamping force is for the regular 993 pressure plate? The OE RS pressure plate that everyone sells as an upgrade is actually the stock (since MY92) 964 pressure plate (blue) which according to SachsNA is not as strong as the stock 993 pressure plate (green) so its not really an upgrade but nobody at Sachs or PCNA could/would tell me the clamping force. Any ideas?

Kevin

Jason there are different plates that are offered for different applications. I would take the high RPM designed lightweight RS plate over the stock unit. However, like I mentioned I would upgrade immediately to the GT2 Turbo plate, regardless.. But as you know, many people buy on price.. That plate is roughly $150.00 more.. If someone DE the car every other weekend, I'd seriously look at the new Race plate, which is rated at over 800Nm. However, without power assist it is pretty firm..

JasonAndreas

but the OE RS plate IS the stock (used on all NA 964s since MY92) 964 plate and not a high RPM designed lightweight as compared to the stock 993 pressure plate that was also used on the more powerful 993RS Clubsport.

Martin - you are correct. I found Bob on this site and he has provided me with untold amounts of phone support, even on stuff I didn't buy from him. No offense to Steve (RS Systems), he does provide alot of support on the site.

Jason - you bring up a very good point. I'll ask Bob when he gets back next week.

Folks the numbering system and supersessions that take place between Porsche and OEM supplies will always create problems.. Similar to what Jason is trying to explain..

First there are vendors that will insert a Stock 964 NA pressure plate for this kit..

Yes, it is a stepping backwords as far as clamping force.. However, it has worked over the years.. I do not recommend that plate..

The entry level plate that I sell is ALSO a 964 part number but it is the "stock" 993TT pressure plate.. Which is a VERY good choice.. But to complicate this even further one could/should request to use the 996TT pressure plate which is a even better solution for clamping..

There is another option that has COME on many RUF cars and many factory teams used another special Sach performance plate.. It has in the past said "Race" on it.. It is my 2nd choice.. Over and above the previous paragraph.. Many 993TT GT2's used this plate... It is NOT a 964 plate nor 993 plate Porsche did not number it... It is a Sachs Perfromance plate.

As I said in my other thread, and with the picture shown, I would sell the 996TT GT2 Performance plate that is above all of these mentioned..

Back to Porsche numerology, if you were to order rod bearings for a 2.7 engine you would get a 914 part number.. And we know that there was never a 2.7 built and install in a 914, production wise (street).. So one has to be VERY cautious as to what he orders and what he gets, But if you received a 964 116 028 53 pressure plate with you light weight kit.. It a good unit!!!

Here are the part numbers for the different models:

964-116-027-90 968 (green)
964-116-028-03 993 (no mark)
964-116-028-53 993 TT & 964 3.6TT (red)
964-116-028-91 964 3.3TT
964-116-028-90 964 (blue)
996-116-027-51 996 GT3 mk1 & 996TT

The 996TT part number that I've posted has probably been superceded so if anyone has it could they correct it?

Do we know what disk comes in Porasche kit 993 116 911 01?
