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.

How reliable with this new engine in the 2022?
They recalled the older engine few years back

Welcome @Kotraders! I imagine Toyota/Subaru are going to tweak it a bit so it's more reliable and more suited for the BRZ/86.

Are you planning on getting a BRZ or GR86?

I am thinking about the brz

Right on, any particular reason over the GR86? Are you a Subaru fan?

Tough for anyone to say at this point. But the FA24 engine in the new BRZ/86 is an evolution of the outgoing FA20, so hopefully they minimized any odds for major recalls through that process. Did you have an 86/BRZ that had to be recalled?

I found this to be a really good video that deep dives into the engine.

I think there might be a few errors with it. It looks like the actual compression ratio is as per the first one at 12.5:1, I think some people got the new 13.5:1 steering ratio mixed up with a compression ratio. Also, the most recent specs point to a 7400rpm rev limiter (as per the first car).
