918 I wouldn't call it just a "low end torque boost", it's more like they're using electric motors to MASSIVELY increase the power to weight ratio. Electric motors have much higher specific output than gasoline engines afterall, and the regeneration is very helpful in racing where you're always on the brakes, so it's basically free energy.

I think a mild hybrid system with a lighter battery pack would be perfect for the BRZ because they'd be able to keep more of the FA20 engine, while providing absolutely monstrous low end torque.

By the way, I just found a website with a lot of rod specs on a lot of engines consolidated, and the lowest rod stroke ratio I can find on an 8000rpm engine is about 1.57, while the FA's rods look like they're in the vicinity of 130mm => 1.50 rod stroke ratio. I wonder if anyone who has engine specs is allowed to release them yet...
