The third generation RX-7 is one of the best sports cars ever built. Unfortunately, it is also one of the worst. The twin-turbocharged FD3S RX-7 is a true sports car in the classic sense: fast, track-ready, fragile and prone to sudden bursts of self-destructive behavior. No surprise, then, that our first few months were spent making preventative modifications like zip-tying every one of the 78 vacuum lines hidden under the intake manifold, installing a larger radiator, and replacing some fragile suspension brackets.
Once cured of its most self-destructive flaws, however, the supercar side of the RX-7 started to show through. The RX-7 combines explosive power and tossable handling in a package that is driver friendly in a way no other car can match.
The original intent of the project was to keep the modifications reasonable, keep the car streetable, and avoid the bigger turbo, more power, bigger turbo spiral of destruction that turns so many Japanese supercars into undrivable dyno queens. So far, that's exactly what we've done. But having reached what is perhaps the peak of street-drivable (or at least street-reasonable) performance, project RX-7 Czar Shiv "give me more" Pathak has started talking about porting, bigger turbos, and programmable engine management. Self control is a fleeting thing.
