After I read what I read I am sorry that I did not make my point more clear.
I think another part of my statement above is that the motor would pretty well
need to be in some sort of turbo form from the factory to make a lower compression ratio and aftermarket monster format work. CR is part of the equation but its also about electronics and manifolds and ICs and packaging.
In the early 90s the Mazda guys made the Miata motor for a turbo (low CR and stout block and pistons) in NA form but anymore I am not sure a car can make emissions numbers by using the same strategy, less so in a heavier car.
If folks want to be a bit different with this car they can avoid the 2.5 and stick with the 2.0 or even cooler would be a 2.2l motor that will rev (square or over square please). They have lots of options in this build and a lot of ways to get to a great final product but sadly there are a lot of very common ways to screw it up as well.
