We're in the realm of the theoretical, anything is speculation at this point. I even wouldn't be surprised if the "STI" version ends up n/a 2.5L. But we'll see. No one's even cracked the ECU yet, so we don't know if there's any potential left in the FA20. There are a lot of rumors.....

Agreed-It really is too early to speculate on the STI engine. If the FA20 is a 8500rpm monster de-tuned for base BRZ/GT-86/FR-S duties, then I could see toyota/subaru going with the high-output version of the same engine to save $$$..
On the other hand, seems like there is a ton of customer demand for some sort of forced induction. Seeing as subaru has confirmed that the next gen WRX will have a turbocharged version of the FA20, it would also make sense for subaru to dump this engine in the "STI" version of the BRZ...

And in the same vain, I would rather have the STI version of the BRZ keep the FA20 and increase the redline to 8500 than go with a 2.5L FA25 and lower the redline. Guess it all comes down to personal preferenece but I'm glad they kept the engine 2.0L and high revving.

Yes- all comes down to personal preference...
