How is this engine the same displacement as the existing 2.4L but it is allegedly not the same engine already in use, as one of the videos said? Did they really build an all-new engine for the second-gen BRZ / 86?

I read in another thread that it's most likely the existing FA24 with lightly worked over head to allow higher revs and more performance. May just be a different cam and valvesprings.

My guess is that it's the same engine just tweaked to make it more sporty. I can't see them building a completely new engine for this car only.

Well the the FA20D is significantly different on the inside to the FA20F according to people that have taken them apart.

Apart from the bore you would imagine that the FA24D has more similarities to the FA20D than the FA24F, with a number of incremental changes and stronger components over the FA20D owing to its increase in torque and the little things they have learnt from the platform.

We will certainly see soon enough!

Not just the increase torque but the fact that it comes at 3,700 rpm instead of 6,400 rpm which will help a lot.
