Diagnosing the turbo on your Subaru WRX before any replacement
Before replacing the turbocharger on your Subaru WRX, it is essential to confirm that the fault actually lies with this component. A thorough diagnosis starts with checking the boost pressure, visually inspecting the turbine for abnormal axial or radial play, and examining the exhaust smoke (blue for an oil leak, black for excess fuel). A sharp whistling noise under acceleration, a noticeable loss of power at high revs, or an engine warning light accompanied by a boost pressure fault code are all characteristic signs of turbo failure on the EJ205 block fitted to the WRX.
Compatibility of this new turbo for the Subaru WRX
This new turbo is compatible with reference 49377-04372, dedicated to the 2.0 Turbo petrol engine (EJ205) of the Subaru WRX. This engine, force-fed by a fixed-geometry turbocharger, is well regarded for its performance but is sensitive to lubrication quality. Before placing an order, please check the reference number on your old turbo to ensure perfect compatibility with your vehicle.
Warranty and delivery for this Subaru WRX turbo
This new turbo is sold as a straightforward purchase with no unit to return: your order involves a single delivery. The new turbo is covered by a 12-month parts warranty, subject to fitting being carried out by a professional. Payment can be spread over multiple instalments, in up to 10 instalments.
Fitting advice for the turbo on your WRX
On the EJ205 engine, premature turbo failure is often caused by insufficient lubrication — whether due to poor-quality oil, missed oil changes, or a clogged air filter allowing contaminants through. Before fitting, check the condition of the oil circuit, the cleanliness of the intake hoses and intercooler, and ensure there are no air leaks. On first start-up, prime the oil circuit by running the engine at idle for a few moments before any load is applied, to ensure immediate lubrication of the turbine shaft.
- Check the oil circuit and its cleanliness
- Inspect the hoses and check for air leaks before fitting
- Prime the turbo with oil before the first start-up
- Regularly inspect the intercooler and air filter
