Some details on 9A1 engine in GT3R
#166
Thanks guys. F engine looks solid so far I must say. Keep your data points flowing for general interest. I'm recording only failed units on my sheet to establish any patterns. Only patters so far is RHS inlet rockers cylinder 4.5,6 and E series engines. I think every example from my 13-14 specific examples has seen track use even if a small amount so therefore some extended redline running.

Boy, looks like it's going to be an interesting after-warranty, used car market with these 991 GT3's -- most of them wrung out to death in the hopes of killing the engine and getting an "improved, attempt #4" replacement before the warranty expires.

"Most of them wrung out to death"???????????????????????? Where do you interpret that information from. If not helpful to the topic, stay off the thread please.

Hyperbole for sure but there have been a few that want to push their motor into failure mode sooner than later...

I expect to be at about 50K miles in 4 years. The car is too much fun to not use it to the full extent my schedule allows. Right now, the biggest concern these issues present for me is that I'm less confident taking the car to a far away track without a trailer, whereas a premise in buying the car was that the hassle of trailering isn't needed. But an upside of trailering would be keeping road miles off the car, so that I can focus the warranty miles on track miles.

Macca,
Here's the additional info regarding my E engine:
Date: July 2015
Mileage: 12,000
It was cylinder 1, a "tare " was noted in the ignition coil. Coil replaced. No further issues.

I believe so. I had similar misfire codes and I was also placed in limp mode, but was able to drive 2 hours home at highway speeds. You just cant go full throttle and the car stutters at low rpm

I wouldn't drive it because you are risking destroying the catalytic converters(big$$$).

After reading the thread a couple of times I am beginning to wonder if the failures that have been reported are really "failures" or is it that some of the engines are wearing out due to track use (albeit prematurely).
I bring the point bcs there would be a world of difference in the aftermarket value of all these cars if the market comes to believe that these issues are deemed to result from flawed engines and therefore time bombs. One thing is highway use and another altogether different is repeated trips to redline and high Gs function. Maybe we were incorrectly expecting that these engines would be flawless regardless of use and that obviously has turned out not the case. Man has yet to invent a perpetually lasting engine.
It is obvious we have been using the term failure in its general acceptance in the sense that the engine has failed to perform. I am not a word smith and not trying to spin this in a different way but I guess we really mean premature wear. Correct?
