1990 Mazda Rx-7

1990 Mazda RX-7 GT-R Built by Stillway $30,000 154,000 km Up for sale is a Japanese market 1990 Mazda RX-7 GT-R that was originally built and used as a demo car by the tuning company Stillway. I bought the car in 2020 from Real Muscle Cars Miami of Miami, Florida after they had imported it from Japan. I ran it as I received it for one year before an apex seal failure in the front rotor took it out of commission for one year. I had the engine rebuilt using all factory Mazda parts, Goopy apex seals and a Turblown stud kit. The engine was rebuilt by CaliStyle Rotary of Eau Claire, WI. Full transmission rebuild by TNS Transmissions in Hales Corners, WI. Brand new synchros, gears, the whole nine yards. ACT clutch and Flywheel. Exedy master and slave cylinders. Many revisions were made during the engine rebuild, including a change over from an HKS F-Con V-pro piggy back to a Banzai Racing prepared A'pex i Power FC with commander. After getting the car back up and running I trailered it to Banzai Racing of Pierceton, Indiana for a final inspection and a base tune. This allowed me to gently break in the new engine for 1,600km. After the break in period, I returned to Banzai Rotary for a full tune and the car is now making a remarkable 350whp on only 10psi of boost off of purely wastegate spring pressure. This is a solid reliable figure that is well within the capabilities of the ignition and fuel system. With the addition of some 2 stroke marine coils and a boost controller, this car can easily make 400+whp. I chose to play it safe. Warning! This vehicle has the oil metering pump deleted. A proper mixture of rotary premix and 91+ octane fuel MUST BE USED AT EVERY FILL UP! This car is an incredible piece of Japanese tuning history, with period correct late 90's aero kit and refurbished Mazdaspeed MS-01 wheels. I have enjoyed my stewardship for the past four years and have decided to part with it to focus on other projects and motorsports.
