About the Mazda RX-7 Collection
J-Spec Garage is your home for Mazda RX-7 performance parts — and the only authorized US distributor of RaceOnly rotary engine components. No other US retailer carries RaceOnly. That exclusivity, combined with one of the deepest FD and FC RX-7 catalogs in the country, makes J-Spec the go-to source for serious rotary builds.
Our Mazda RX-7 collection covers over 2,100 products for the FD3S RX-7 (1992–2002, 13B-REW twin-turbo) and the FC3S RX-7 (1986–1991, 13B-T turbocharged). You'll find everything from apex seals, e-shaft components, and rotor housings to turbochargers, fuel system upgrades, standalone engine management, suspension, brakes, cooling, and interior — for every stage of build from a daily street rebuild to a high-horsepower track setup.
Key categories include RaceOnly billet CNC rotary parts, 13B-REW rebuild components, single turbo conversion kits, sequential twin-turbo upgrades, fuel rails and injectors, standalone ECUs, coilovers, and big brake kits. Brands stocked include RaceOnly, HKS, GReddy, Injector Dynamics, Haltech, ECUMaster, Turbosmart, Garrett, Brian Crower, DBA Brakes, and Chase Bays, among many more.
The FD RX-7 is one of the most rewarding — and most demanding — platforms to build. Get it right with parts you can trust, backed by our price match guarantee and fast US shipping.
