Yes. Turbo on a 2.5L Duratec four cylinder running E85.
It should be good for 500-550hp at the crank before any detuning. Assuming I can get the car to ~ 2,600lbs or a little under, 4.7-5.2lbs/hp seems like it should move out pretty well while not upsetting the chassis balance or Cg of the RX-8 platform.
