I would appreciate hearing from anyone with experience with modifying a Mazda RX-7 engine for street use. Headers and manifold/carb changes are recom- mended by suppliers such as Rotary Engineering and Racing Beat. Are their claims of power increase and improved throttle response realized? What about cold starting (down to 0 deg), noise, and mileage? Ease of ins- tallation? Please reply by mail and I'll summarize to the net if there's enough interest.
