         Lynn,

          A little off topic but I am in total agreement. I love my second gen.   88 RX7 but when its 13B lost compression in the rear rotor I replaced it with
  a 4.3L Chevrolet V6,throttle body injected and a Turbo Hydro 2004R overdrive
  transmission. It gets 25 mpg on the road is a blast to drive. I chose the V6
  over the V8 because I could use the RX7 radiator and leave the battery in the
  stock position. The combination of 3.90 rear-end (2nd gen. automatic cars),
  26.5 inch rear tires and the .70 overdrive ratio give a final drive ratio of
  2.73 and keeps the cruising rpm within reason for the V6. I have about 15,000
  miles on it at present.
         I consider the 13B wasted in an everyday road car. Even Mazda engineers
  knew the worst case application for the rotary was an automobile. It is not
  efficient at the rpm typically used to lug a auto around. IMHO is at its best
  in aircraft or pure race cars.
         If any on the list wants to save a good donor Mazda (Its eng. being
  used for an A/C)from the scrap heap dial up <google.com>, then search Kelly
  Troyer to see photos of my RX7. The website is "Granny's Speed Shop" in Concrete,
  Washington. They have conversion parts and info for all three generations of
  the RX7.
