How many 15-16 gt3's have engine replaced?

Sent a 2016 to the dealer two weeks ago after I noticed something internally wrong with the engine in the high RPM's. Was told a cylinder had issues that they needed to determine. It was not misfiring and I new it was mechanical before it was sent to the dealer. They determined it wasn't an easy fix and a new engine is on its way to the dealer!!! This is very very exciting new for me! I'm very happy to get a fresh new engine in the car, now the next thing i need is a new clutch and I'm golden

Open your deck lid - look for the white label - it will indicate MA XXXX. Unless your engine has been switched out, this should tell what is in the car.

This might need more clarification. What did you feel was mechanically wrong at high RPM? Maybe elaborate on your specific problems. Also, what was the process with the dealer inspection and their final determination of the cylinder damage that requires a new engine.Specifically, the part of not being an "easy fix". This could be very helpful.

While doing a second gear pull the engine would mechanically stop at 8,100 rpm give or take a 100... and i would immediately let off to avoid doing any damage. Essentially the first time it happened the car actually decelerated at 8000rpm even with WOT, and i could feel the deceleration and aggressive jerk, knowing it wasn't a electronic cut of ignition or fuel. It just felt like the inside of the engine wanted to stop spinning and it immediately sent a check engine light.

I'm a bit sceptical regarding to RS and R. The parts catalogue says the topend is exactly the same. So this engines should also be prone to the problem.
With later G (G1/G6 however...) they introduced the DLC coated camshafts. Maybe thats the solution - but not all the RS have these camshafts installed.

This will sound obvious, I've always understood that most engine failures will occur at high RPM and a constant heavy load, a track situation. I am very interested to find out if any cars that have never been tracked had the same failure and if this occurred at relatively low RPM and normal driving conditions. Two track days so far with G0 engine, and nothing unusual except for 1/2 quart of oil after.
And if I recall correctly, at one point in time (Pebble Beach?) AP or another VIP at Porsche mentioned that the problem may be EXACERBATED by low rpm driving.
Regardless, we have examples of low/no track miles in the group, but we also have examples of cars with high track mileage that have had no problems at all.

I believe there are cases of misfires on cars that had not seen any track time.

On another note, I am waiting to hear back from the dealership. I did get a 3,200 mile 991.2 Carrera as a loaner. Nice car, but it establishes even more how much I love the GT3.

You are correct on the causes. These are what Walliser pointed out in his presentation.

My understanding was it is the low rpm, around town driving (along with having the inclusions from the casting) that create the failure. Rob or someone from the meeting can confirm for sure, but that is how I interpreted it.

So basically there is no specific pattern of driving that causes the engine failure.

AFAIK, nobody's engine has grenaded over this issue. It develops a timing problem that the ECU recognizes is out of spec, but not catastrophically so.
Or did I REALLY miss a couple of major pages in the thread?

I know it will be almost impossible to stop this train, but might we possibly stop using the term 'failure?'

1) Premature wear of component original life cycle (failure)
2) Debris material of the components premature wear, circulating the engine which can cause further damage.
