3rd-generation RX-7's are not only the zenith of the model's performance abilities, they're also the end of the line (so far) for the 2-door Wankel sports car. Turbo models were fitted with a staged turbocharger system that used two different compressors to boost power across the entire rev range. It was effective in stock trim, though it's less than celebrated by the crowd that likes to tweak on their 7s. Grand Nationals, too, were the baddest of badass A/G body GMs. The 231 V6 with a Garrett snail hung off the front was impressive in stock form, is capable of silly-to-ridiculous power levels when fiddled with, and still returns reasonable fuel mileage,which mirrors the seller's claim. As much as we recoiled at the initial thought of this particular swap, the car is obviously fussed over. Shoot, it's got a Dana 44 rear from a Viper for crying out loud, and it is an appropriate shade of GN black. Gather something north of 16 grand together and bid away!
