In 1984 the Mazda received some huge performance changes in its last two years of production like widening the combustion chambers, which made more displacement, which meant more power. They increased the intake ports from 4 to 6 to let more fuel/air mixture into the chamber for more power. Mazda sold around 370,00 first generation RX-7ís.
