Mazda RX-7 Tuned current version Unknown

Because of its nature, the rotary engine is able to run at higher speeds without suffering the detrimental forces of a common engine. This means the owner is not forced to focus on extensive modifications to preserve engine's lifetime.

The main steps are remapping the engine, replacing the original turbo system with a bigger unit, improving the air filter to have a higher flow (very important for rotary engines), exhaust pipe and, of course, installing a big rear wing because the rear is really light at high speeds.
