Impreza WRX STI Manual Gearbox Exchange

Manual Gearbox Exchange for the Subaru Impreza WRX STI: a remanufactured manual gearbox with new bearings and synchromesh.

Clutches and gearboxes on these cars fail in known ways: the Type R and STI clutch under added torque, the Evo active centre differential pump, the GT-R dual clutch gearbox, and CVTs on everyday cars that were never given a fluid change. Every package here says what failure it answers and what it will and will not hold. The Impreza STI's EJ257 is a strong engine that punishes poor oil control and aggressive tuning with ringland failure, so we sell the parts to build it properly.

Fitting

Labour guide: about 8 hours. Japanese manufacturers change parts by build date and by market, and grey imports add a second layer to that. Send the VIN or chassis number with the order and we confirm the part against the build data before anything is dispatched. For imported cars send the chassis plate, because the UK registration will not tell us enough. We are an independent parts specialist for Japanese cars. We are not Toyota, Honda, Nissan, Mazda, Subaru or Mitsubishi and are not appointed by any of them; the names are their trademarks and are used here to describe fitment. We stock genuine, OEM and quality aftermarket side by side and every listing says which is which, because the price difference is real and so, sometimes, is the quality difference.

Which version to buy

Remanufactured is rebuilt to specification with new wear parts and tested, with a surcharge refunded on your old unit. New Unit is a brand new unit rather than an exchange.
