RX-7's like URBANRCR said are not a do it yourselfer starter car. It truely is an exotic. The 3rd gen rotory turbo engine is fragile if pushed with to much boost. The apex seals will be the first to go if pushed, especially on a higher milage engine. Heat is the other thing that kills the 3rd gen RX7. The underhood temps can cause problems if not monitored and corrected.
The best RX7 guy in the area is Scott at Mazspeed in St. Pete. My buddy takes his RX7 there for everything.
