Shell number = production number = VIN

I think the most interesting thing here is the research we do into the history of these cars. One time they were worth very little and no one took the time to keep records or cared when they were sold on.... but now the values have dramatically climbed provenance with history and knowing what you got is vital.

Normally these take us back to the Service Book and Frahzbrief, where we google away tracing owners and dealers going back nearly twenty years. Some respond most don't ..... a lot of cars come with "stories" such as factory extras, famous drivers, never raced, never crashed etc etc etc these stories normally come from retailers who you beleive at the time ...... but once you start digging a silmilar but different picture emerges. This can be to your benefit where you discover for instance some race provenance or indeed the most common you have a rare factory press car or downside it was crashed.

But as values climb this detective work is so important, but now an important part of ownership.

Agreed Des.

And a really good generic history of a collectable car plus then the specifics of a particular car -- even better if interesting or unique, must surely add provenance for the future, and value in time.

Speaking for my own experience with the development 993RS, whilst this can take a lot of time (a work in progress for me), it can also make a really interesting read.

History in 3d --- some of these cars are for me, closer to being works of Art than almost anything else.

And of course the most sought after works of art are those signed by their creator. []

Now we really are moving into fiction!!!

Came across this website the other day, and it's true it's a HUGE help for newcomers to the breed given histories of ownership/ ebay and auction.
Clearly it's a labour of love for someone but I think it's something we should perhaps aspire too while we are preserving these cars for the next generation:

apologies it's Dancing Donkeys... but look at the detail for each individual car::

[964rsdatabase]

It's a nice site. Very informative. All good - in theory. The reason I have no specific data available for public viewing on my database is because that's what the majority of owners wanted. The only reason I have as many cars as I do is because the info is NOT available. And even then some owners are still not willing to part with a chassis number. I frequently get asked questions like "What's in it for me?" As my database is only a hobby and not a business, the only thing I can offer is free advertising. Anybody with anything 964 RS related for sale or wanted, I will advertise in my Classifieds section.

Luckily, I do now have a couple of dealers who very kindly give me info on their sales cars which helps a great deal but it is becoming increasingly difficult to find new cars here and abroad. I'm not gonna give up though!

To all those who have registered, thank you. []

To those who haven't. [8D]

Martin, it would be really nice to think that those who got to you first with their Vin number have the original car ...

We all know that there will be clones --- and who, long term, will be able to say which has the originality cache without your database ?

 

[paul howells]

Fairly sure there is not a lot of difference between a proper 964 3.8rs engine,M64/04 (i think)! and a rsr motor,as all heads/valve sizes/ports etc would have been to homologate the rsr version.Higher lift cams for more bhp at higher rpm,similar torque.
Cant remember with out looking up if the 3.8 rs had a flat belt fan drive,the rsr do and have different cranks with a taper for the bottom pulley and vibration damper.
It would be important to get the correct type number engine.
I have a 993rsr M64/75engine and a 964rsr engine in parts ready for rebuilds some time.Some very trick factory lwt rockers on both engines.
I could always ask my contact at PMS if they still have any spare engines on the shelf,they certainly used to.
Happy new year all

 

[ChrisW]

Happy New Year Paul, --- you have some very useful friends []

Martin - I agree with statements above, over time the database will become key to understanding originality of the cars. Owners get their car known to the RS community as a result of adding info, that alone should be worth it.

......which has always been my concern............

 

[964rsdatabase]

As I get more and more info there is a very obvious pattern of engine and gearbox numbers building up. Not always running concurrently but a very definite pattern. For instance, out of the first 4 cars on the database, the engine number range is within 5 digits. Therefore it shouldn't be hard to work out the supposed engine number I don't have. But interestingly, the next car (mine) which is 8 chassis numbers away, has an engine number which is nearly 300 digits away! And the cars after mine all follow closely in sequence, so what happened to nearly 300 engines between chassis numbers 0068 and 0076?

Off to polish my anorak! []

 

[carreraboy]

They went ino a special development department of Porsche Motorsport Weissach for the future GT1 ......you think I am joking, but did you realise the 964 shares the same engine block as the 962(C), GT1 and MK1 996GT3 .... OK the first bit a laugh, but where did Porsche get their development engines for the GT1?

 

[ChrisW]

And the later GT3's do have RMS and FMS issues from 996 GT3RS on ...

I have not heard of these issues on 996GT3 MkI, so what happened ?

 

[RSR]

All 911 engines can (and do eventually) develop leaks on the RMS behind the flywheel. I've replaced them on 964 and 993, especially when doing the clutch anyway. The parts dead cheap and it's an extra hour to do.

I believe it became a problem with the water cooled engines because the edge of the crank case / RMS is further away from the last main crank bearing allowing more potential wear of the seal, especially with a heavier clutch / flywheel combination.

 

[ChrisW]

I also read that crankcase pressures are significantly higher on the later higher revving engines.

The MkI "only" runs to 7600 rpm ...

996 MKII runs to 8200 ?? and 997 to 8400 ??
