The best parts for a 1992-2002 Mazda RX-7 (FD) depend on your goal. For a street car, the smartest money goes to reliability first - cooling upgrades, fresh ignition, and fuel system support - before any power mods. For a track or show FD, the popular path is a single-turbo conversion with supporting fuel and ECU, plus suspension and aero. Either way, never add power without addressing heat.
The FD RX-7 is a legend: a lightweight chassis wrapped around a sequential twin-turbo 13B-REW. But these cars are now 25+ years old, and tired cooling systems, worn ignition, and original fuel components are the usual suspects behind expensive failures. Experienced owners mod in order: reliability and cooling first, then breathing (intake, downpipe, exhaust), then fuel and a proper tune, and only then more boost. Anything that changes airflow or fueling on a rotary needs tuning to stay safe.
Brands FD owners trust from our catalog include Motul for oils and fluids, Mishimoto for cooling and engine dress-up, and Seibon for carbon fiber aero. Also browse the Mazda collection and the 1985-1992 RX-7 (FC) collection.

1992-2002 Mazda RX-7 (FD) Parts FAQ
What are the first reliability mods for an FD RX-7?
Cooling (radiator, hoses, fans), fresh ignition components, and checking the fuel system top the list. Most FD failures trace back to heat or fuel delivery, not the rotary design itself.
Does an FD RX-7 need a tune for bolt-on mods?
Yes for anything that changes airflow or fueling - intake, downpipe, exhaust, or boost changes. A rotary running lean will not forgive it, so a proper ECU tune is mandatory with power mods.
Should I keep the sequential twins or go single turbo?
Healthy stock twins are great for street response and keep the car original. A single turbo simplifies the engine bay and raises the power ceiling, but needs fuel, ECU, and cooling support to run safely.
How do I keep my 13B-REW healthy long term?
Warm the engine fully before driving hard, never shut it down stone cold after a hot run, check oil often, and keep up with ignition maintenance. A compression test is the best health check for any rotary.
