It was truly a leap of faith when Tim Eull purchased his completely stock 1993 Mazda FD3S RX-7 R1 in March 2000. The car was for sale on eBay and he purchased it sight unseen, despite it being located in Mililani, Hawaii – a long way from his Arizona home.
He has worked on the car extensively from when it was purchased, utilizing period-correct modifications and unique touches that make this car a true future collectible. For all internal combustion engines, but especially rotary engines, heat is the enemy. The car is powered by a Mazda Rotary 1.3-liter BREW engine and in its stock form uses twin Hitachi turbos and a series of solenoids to deliver smooth acceleration through the powerband. That cast-iron twin-turbo setup, along with the complexity of the turbo control system, generates a considerable amount of heat in the engine compartment. By the early 2000s, advances with small, single-ball-bearing turbos were delivering comparable performance in a simplified package that ran cooler, so the car’s turbos were switched to the single-ball-bearing version. As it sits, the car generates 460 horsepower at 16.5 psi of boost.
