Prefer low engine hour car that already has PCA Club Racing log book (old D class).

Are you looking for a 993 for performance or aesthetics? If you want performance and reliability then I think it's widely accepted that the 964 is the better car and cheaper too. You can then run big brakes, additional wing, chip etc to get you into G.

I agree that the 964 is a better bargain and extremely capable car, but why do you think a 993 is less reliable than a 964?

Mark,

We exchanged pm's on this remember? You even said you have a spare motor . The valve guides and CEL was the issue we were discussing. There's a major thread on this somewhere ion Rennlist. Plus, with single mass flywheel, headers and muffler I think the 964 can get close to the same hp as the 993 and run lighter.

CEL is a function of the OBDII and will affect your emissions inspection, but for a dedicated track car is irrelevant. Guide wear is an affliction for both the 993 and the 964 according to Joel Reiser. I think you will find both cars will be close this year with the new classifications.

Tristan,

I never meant to imply that I thought the 993 was less reliable and honestly don't recall saying that the CEL is an issue that pertains to reliability, unless you had to worry about emissions, which maybe you do. What I do recall saying is that I thought the 964 is a more flexible platform that can do very well in the old E, D and C classes and that I would choose it over the 993.

I would have bought a spare motor, even if I had a 964, for I think it makes sense no matter what type of car you're racing. As Bob mentions, valve guide wear is not exclusive to 993's, not that I think it counts as a classic reliability issue. My definition of reliability encompasses things that break and prevent you from racing/tracking or putting you into the tire wall such as a broken shifter fork, weak suspension arms, fragile ring and pinion, grenading motor, etc.

Oh hang on...I'd better get moving on that Revised Club Racing Pre-Race Checklist:

1. Helmet - check!
2. Gloves - check!
3. Rain tires - check!
4. Spare brake pads - check!
5. Spare motor - oh sh@#t!

6. Spare transmission
7. Spare clutch and TO bearing
8. Extra set of wheels/drys
9. a ka-billion other things
10.

why do you think that it is easier to run big brakes on a 964 than on a 993?

JMO(and not worth much), but it's far easier to run better brakes, wheels and tires on a 993 than on a 964

Mark in Baltimore

If a racer wants to run in G class (old D class), running bigger brakes on a 993 forces a bump into prepared and, hence, H class (old C class).

Enjoyable to see what this thread has started! I am actually looking for a 911 that is competitive in the upper stock classes. If any of you know of any race ready 964's for sale out there, please let me know.

Bill Verburg

I was only commenting on the ease of adapting brakes and wheel and tires to a 993 vs 964

wouldn't adapting bigger brakes to a 964 similarly bump one up?

Mark in Baltimore

Bill,

The 964 runs in class in E. I think you can run big brakes and a wing and be in D class if you are at a certain, higher weight. Jeff Curtis' car is a good example of a 964 with big reds and a wing in D.
