Subaru's boxer motor is a brand distinction tool at this point - nothing else. Zero to be gained.

I hear you about the 98% quip, but including components in that list which only appear in Subabru engines (or elsewhere only in Subaru models) doesn't make them Toyota parts, despite the parent company's ownership. At least, not to me.

Low — Our highest priority

From the start, the BRZ was engineered to accentuate the inherently low center of gravity of the SUBARU BOXERŽ engine. The engine was designed to be as compact as possible, allowing it to be mounted lower in the chassis. Then we moved everything around it lower as well—from the roofline to the seating position—yielding a supercar-like center of gravity height of 18.11 inches and planting the BRZ firmly to the ground for otherworldly response.
What car has a lower center of gravity than the BRZ?

And yet are plenty of cars out there with inline or vee motors which outhandle the BRZ. Marketing.

For the price, you must admit, the CoG is nothing to scoff at. Of course there are cars with lower CoG though.

Something in the vein of S-chassis and original AE86's.
Therefore, there was room left for improvements in the car in pretty much every area.

I am an automotive designer in the aftermarket, and the 86 twins have one of the largest aftermarkets in the world, because they are one of the most modified cars out there.
Pretty much anything you want to do with the car is addressed in the aftermarket.

One of the big reasons you don't see a factory 86 twin with a higher power output is because if they did come out with one, the price would be increased to the point where you would see two major arguments against it;
1."For this much money, you could get a _______ instead."
2."For less money, you could just get a base model and install a supercharger on it."

If you don't believe me on the second one, look at how many people were saying similar things about the BRZ tS? "For less money than the tS, I could install coil-overs and better tires, and be at tS level with cash in my pocket."

The truth of the matter is that the 86 is an old design, and at this point it wouldn't make financial sense to do a major re-engineering this late into the model-cycle, only to try to sell a more expensive version to all the people on the internet that say they would buy an 86 if it had more power, when in reality 98% of them are all talk, and would still find a reason not to buy it.
It makes much more sense to address it in a new generation of the car.

ND is probably within a tenth. Corvette is lower. The only reason you know the cog is marketing. Which ones have a higher one? How many cogs are you aware of?

Corvette is 17.5" - the same as an ND Miata with the top down - See my previous post.
