Predominantly, it's an issue of classing, I think. In STX right now, within a year, the Toyobarus have found setups that work. They weigh approximately 400lbs less than a US spec E82 yet can run 17x9 wheels w/ 255 rubber all day. From the ground up, it seems like a superior car for solo. Sure the 1'er has more power, but with more mass, and the same, or less tire than the twins, it's going to be working the tires a lot harder.

I'm in no way trying to deter you, there's a reason I have an 135i and not an FR-S. I was just curious what your mindset was going into this.
My BRZ was 2,550 lbs with 208whp/ 164wtq with e85. On 93 it was 193whp.

What kind of hp/tq would the 128 make?

Conservative would be 3000 lbs (assuming seats, wheels, exhaust mods)

With headers and tune, I would hope yo get 220-230 at the wheels....which should be very easy to achieve. that'll but me at similar figures as the BRZ
