If it needs an engine and gearbox refresh, the latter

Of interest to a collector perhaps?

Did that advert really say " cheap to run" ?

The words GT3 and cheap don't go together at all... Let alone that magic word "cup" !!!

Yes that line did catch my eye too..

I thought this might be a good garage addition to my existing 6.2 gt3, and at c1/2 the price of a road car it looks attractive on the face of it.

Seems the consensus from those in the know then is not to touch it with a barge pole, unless you happen to have suitcases of spare cash and a race team already on the payroll to keep it going!

These cars are very like a regular gt3, relatively speaking. It's all about the engine refresh on this one. It's wearing 24hour race stickers. After a 24 hour race at race pace you are talking a full rebuild as I understand it - that's pricey. If that refresh was done last week then you are looking good.

With a gt3 engine, very similar to a road car, a normal box, hefty brakes and less weight it's a sensible track car. Clearly running any 911 on track is a very expensive hobby but with these they are akin to a road gt3 but lighter. I ran one for 3 years and it was painless. Didn't touch the engine and consumables on the box/diff/brakes. I rather miss it. A road car wouldn't see which way you went, plus you'd need to spend a multiple of this to buy said road car in the first place.

Why does a Cup engine and for that case a Cup gearbox need to be rebuilt after such a short time. I under stand if a car is used for racing then a increased wear rate is only to be expected but if theoretically you ran the cup car on the road ignoring the clutch gearbox not being good on the road would you expect increased wear in the engine components and if so what components

My memory is that the engine and gearbox on these are lifed at 25 hours before needing a refresh. No idea why but race engines are built to fine tolerances and operating at close to max revs for a very high % of the time.

This is more or less what I was saying below. Used at race pace for a long time necessitates a rebuild, but the 25 hours suggested is 3 seasons of club racing if you don't do every race. Also, for an older race car like this one the typical owner pushes those recommended boundaries as they are not racing to win the Carerra Cup in support of the F1 race!

I had an early 996 Cup and my understanding was that it was pretty much an off the shelf road engine and box. It was cheap in race car terms so the approach we used was light care and maintenance as needed. This works fine for the box, suspension etc. We wondered about the engine, but it ran fine, had good compression, the oil and coolant were clean and it seemed to be at expected power; given I was doing 4 or 5 races a year we were in no rush to rebuild.

I have a mate with a 996 Cup car, which has more than 80hrs on its original engine. Still has perfect compression, uses no oil and still makes crank 405hp on a Mustang Dyno. Raced for one season in Germany when new, then retired and used as a track car since then with regular preventative maintenance. Original H-pattern box has had one rebuild and so has the diff.
