What turbo parts fit my Subaru WRX STI 2004–2007 (GD chassis)?
Every turbo part in this collection is fitment-tagged for the GD-chassis WRX STI (2004–2007) with the EJ257 and factory top-mount intercooler. The factory turbo splits by year — VF39 for 2004–2006, VF43 for 2007 — so confirm your model year and factory turbo on the product page before ordering.
Which factory turbo does my GD STI have, a VF39 or a VF43?
By year: 2004–2006 STIs run the IHI VF39, and the 2007 STI switched to the VF43, which has a different wastegate actuator than the VF39. Turbo, actuator and related parts should be ordered against the turbo your car actually has, so check the model year in the fitment notes before you order.
