With the Gt3 engine they kept it a dry sump while all other engines, including the Turbo still have the standard oil pump and an "integrated dry sump" (aka wet sump).

The failures start with a low oil pressure dash warning, then the driver hears a noise, gets out of the car, finds oil leaking and then a fire ensues. Thats the description that was included in several articles about this issue.

My hypothesis is the engine gains an oil leak and the pressure loss is because the oil thats being lost is under pressure. When the engine shuts down some residual pressure is still there, which sprays onto the exhaust and then you have a fire. This can also be happening when the car is pulled over because air is all around the under side of the engine while the car is moving, which blows the oil away from the exhaust a bit; but when the car stops, air becomes stagnate the fire erupts.

Again, thats only my hypothesis from looking at the under side of the engine and where things are laid out, some of which makes no sense, like the heat exchanger thats UNDER the engine and mounted low ? Road hazard from hell!

Needless to say, I am working super hard to understand this and design my own fix for it. I had a customer who had a new GT3 on order when this happened. He was going to ship me the car as soon as he received it, for me to take it as large as I dared (4.4L). I only wish I had the car here and had killed its warranty on purpose, then I'd have to understand the issue and design my own fix for it, because we would have killed its warranty, on purpose :-)
