Default 991.1 GT3RS failures

I would be interested to hear from owners of 991.1 GT3RS that have suffered serious mechanical failure - particularly the engine or transmission. Please feel free to send me a private message in confidence.

Thanks.

Interested to know of one as well

Great car and mechanicals seem to be working well through 4K miles

I hammered my .1 RS with 16,500 miles and over 2 1/2 years with 35 track days. Only problem I had was one bad thermostat. Otherwise that engine/transmission was freaking bullet proof.

To put this in context, I am aware of at least three cars with replacement engines and two with replacement gearboxes. I am trying to determine if either of these (or any other) issues are more widespread - and per the 991.1 GT3. All the 991.1 GT3RS cars I am aware of have been used as Porsche intended. All have been covered by warranty.

More reliable than the 997 RS. Almost zero confirmed engine issues.

991.1 GT3 RS only revs to 8500rpm (except from 1st to 2nd gear, and 1st has no place on a racetrack). This rev range is similar to the 997 GT cars.

Agree, there were more engine problems with the 996 GT3, 997 GT3 and plenty more with the 991.1 GT3 (the 9,000rpm 3.8 engine).

911 R (991 series) and 991.1 GT3 RS use the same engine. This engine is also a true Motorsports engine, it ran in the 911 GT3 Cup R race car.

Collectively, there are hundreds of thousands of Track miles on this forum alone, and no engine failures.

It would be nice if the OP can provide details on the 3 engine failures he knows of. Lots of things can break an engine, tunes, bad fuel, old oil, maintenance negligence (very common on cars with low miles barely driven), abusing the engine when cold, I would call all of these serious driver failures.

The 991.1 RS is a tank, robust, runs all day, it is the first car I own that comes from a track session as relaxed as it entered the track.

I am keen to know too. I have used mine on track pretty extensively and am now at 9000miles. Zero issues so far, but currently undergoing a P111 to extend the warranty. On the 996 or 997 I have done many more miles but never even considered warranty. Curious if the issues with the 991 are exaggerated or just more prevalent due to the higher production numbers and increased track use.

Obviously it did not have the same issues as GT3.

Don't over think things, you'll never buy a car.
This right here.....there's no such thing as a car without some isolated issues.....sounds like you're looking for a pattern and at this point you won't find one....

Mine has done 30000km's: no engine or gearbox issues.

Friend got a new engine because of abnormal oil usage.

And in fairness, the .1 GT3 only had one flaw as well (now completely resolved and warrantied). Besides the finger followers the car is bullet proof as well. The thermostat is the only issue and it effects the RS as well. Pretty solid cars IMO.

Default 991.1 RS Engine failure

Interesting topic.
I had engine changed under warranty after 5k km, due to misfire.

Since then its bullet proof so far 15k km more.

This is one of the issues I am aware of and would like to better understand how common it is. A number of isolated cases is what is otherwise known as a pattern.

Did your friend receive a new or reconditioned engine and did Porsche offer anything else?
