I'm just wondering if anyone here has there Z going 0-60 in the 4-6 second range. I've just been wondering lately what it would take to get a Z to perform more like a sport bike ie. starting and stopping. My Z feels too heavy for the amount of power the engine is putting out but rather than go with a V8 I would rather stick with a 6 cylinder with a lighter car and probably more horsepower. Have there been any Toyota Supra Twin Turbo conversions?
