Savanna Rx-7
before I parted my cosmo out my fuel mileage was 3.5 km/litre with the stock turbos, and a FEED high boost computer. funny thing was it didn't matter how I drove it, if I had AC on or off, it was always around 3.5
when i changed to the IHI turbo setup it dropped to about 2.7~3 km/litre and it became very sensitive to how I drove it, but that was with about 600 RWHP too so it was to be expected.

I'm sure that guys that can afford a 20B aren't too worried about the fuel economy. No offense or anything. You pose a real legit question. But if you're worried about it, you might not want to get it
