When did Porsche get their _hit together on these motors?

No, just stating what we see routinely. You must understand that we do not see best case scenarios, we do not do normal work at a normal shop level. All that we see is extreme and has usually already been manipulated by other shops that don't have a clue, so we have to pick up the pieces and start from scratch.
What I was stating more than anything is the bigger, later engines are NOT any better than those that preceded them, contrary to popular belief. These engines have proven to be some of the most problematic with the most failure modes.
All M96 and M97 engines are created equally and none are better or worse than others, it seems.
The DFI 9a1 engines have been our focus for the past 3 years already, I recently tore into one with 4100 miles to carry out our big bore process that increases displacement from 3.4 to 4.2 liters. The engine had no symptoms and was being built bigger for "no reason at all". We carried out a "before dyno" prior to disassembly so we could have a comparative after our work is finished. The dyno results were the lowest we'd seen from any DFI 3.4 Cayman spec engine and even a track engine with 14K miles on it (all on track) had beaten it. Upon disassembly I found two missing O rings from the oil system, a broken piston ring, scored cylinders and worn out lifters. I have documented all of this, and the engine had never even had its first oil service and had never been to the track.
BTW- We currently have 13 months worth of engines to create and of those only 5-6 of the cars have more street value than what is being spent on my reconstructed engines. The people that look our way have a different way of placing a value on their car. Since 1992 I have been building engines for customers that are spending more on my engine than the entire car is worth- thats nothing new with Porsches. The reason they don't care is because they never sell the car, so what the vehicle is worth is only determined by how much time in service it gives them.
I have a 2014 GT3 on the way here and it will have only 3-4K miles on it when we strip the engine down to make it as large as efficiently possible. We'll know more about it in just a few months and I am positive we'll have our hands inside one of these before anyone outside the factory (again).
