Interesting facts:
- The car is all steel bodied with no composite panels. It's a true Tin Top Doorslammer!
- The RX-7 body is standard, with back and front half tube chassis.
- The 20B three rotor engine uses no electronics for injection. The system is completely mechanical, and requires astute tuning skills on race day.
- No high tech gear in this car - it's a true 70's style drag car with attitude, set to take on the rice burners in Sport Compact.
