Don't forget the ND MIata; it weighs only 2,300 lbsAgreed. The weight is about the same as the S2000, slightly less HP but more torque, so it should be a pretty fun car to drive.
I hope it will fit a 9" wheel in the front like the S2000. That and either a STI or TRD/GR version... even without boost.
I have a 2018 124 Spider Abarth: it weighs 2,400 lbs with the manual transmission. The Fiat 1.4 turbo motor is a hoot!
