What You Need

The key to the 818 being completed for under $15,000 is to use as many parts from the donor car as possible. The parts needed from a 2002-2007 Subaru Impreza/WRX sedan or wagon (except STI models*) include the following:

  • subaru-donorFront spindles with full brakes and front lower control arms
  • Rear spindles with brakes and E-brake handle/cables
  • Steering rack, tie rod ends, and upper steering column assembly
  • Pedal box and throttle pedal
  • Master cylinder and brake booster, and clutch master cylinder
  • Engine with turbo and intercooler (if WRX model)
  • Exhaust manifolds, O2 sensors, and down tube
  • Transmission
  • Rear lower control arms, toe links, and CV joints
  • Front seats, front seat belts, and gauge pod
  • Fuel pump and fuel level assemblies
  • Radiator and fan
  • Wheels and tires
  • Door hinges, rear with latches, strikers, and inside door handles
  • Side view mirrors, left and right
  • Rear view mirror
  • Rear seat belts

*You can use a 2004-2007 Subaru STI as a donor car for your 818 build including the engine, but not as a single donor car build. The following parts will need to be sourced from an Impreza/WRX:

  • Front spindles and hubs
  • Rear spindles and hubs
  • CV Axles
  • Transmission (Pre-2006 STI transmissions will not work with the 2 wheel drive adapter)
  • Wiring harness
