Subaru Impreza WRX GD Performance Parts & Upgrades

The Subaru Impreza WRX (GD sedan and GG wagon) was sold new in Australia from late 2000 to 2007, with a turbocharged boxer four and all-wheel drive. Early cars use the 2.0L EJ205 and the last models the 2.5L EJ255. Many parts are shared with the GD STI. This page lists the parts we stock for the GD WRX, from COBB, Perrin and GrimmSpeed intake, turbo and exhaust parts to HARDRACE bushes and mounts, Process West intercoolers, Torque Solution shifter bushings and Turbosmart and GFB blow off valves.

Popular upgrades for the GD WRX
  • Intake and turbo: COBB, Perrin and Process West intakes, turbo heat shields, boost solenoids, and GFB and Turbosmart blow off valves.
  • Intercooling and cooling: COBB and Process West front mount intercoolers, COBB CSF and KOYORAD radiators, and Mishimoto and Perrin oil coolers.
  • Exhaust: COBB and Borla cat-backs, a Borla header, KORSH downpipes, and COBB and GrimmSpeed up pipes.
  • Suspension and bushes: AST coilovers and springs, HARDRACE and Perrin bushings, end links and engine mounts, and Perrin and GrimmSpeed wheel spacers.
  • Driveline and shifter: COBB shifters, Torque Solution shifter bushings, and Drive Shaft Shop axles and driveshafts.
  • Engine: Cometic head gaskets, Supertech and GSC valvetrain, Manley rods and ACL bearings.
Choosing the Right Part
  • Front end style: the GD was facelifted twice, for 2003 and 2006. Process West intercoolers come in Bugeye, Blobeye and Hawkeye versions.
  • EJ20 or EJ25: 2.0L and 2.5L cars need different head gaskets, pistons and some turbo parts. Check your engine before ordering.
  • WRX or STI: the STI has a 6-speed gearbox and different brakes. Driveline and shifter parts are often listed for one model only.
  • Sedan or wagon: most parts fit both, but check the title for springs and exhausts.
Installation

Have a qualified workshop fit suspension, brake, fuel and engine parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Fuel and engine upgrades usually need a tune to suit, so ask us if you're unsure.
