New Subaru Impreza 2.5 WRX Turbo – Ref. 49477-04000

A brand-new turbo built for the sporting character of the Impreza WRX GT

The Subaru Impreza WRX GT, powered by the supercharged 2.5 EJ255 petrol engine, is built for dynamic driving: sharp acceleration, frequent high-revving and sometimes demanding use on twisty roads or track. This style of driving puts the turbocharger under considerable strain, with significant pressure and temperature fluctuations at every push. Over time, these repeated stresses can weaken the bearings, seals or wastegate actuator geometry. To restore your Impreza WRX GT to its original responsiveness, this brand-new turbo — compatible with reference 49477-04000 — is a reliable solution designed specifically for your vehicle.

Tips for a successful installation on your WRX GT

Before fitting the turbo, several checks are essential to protect its service life on a performance engine like the EJ255:

• Check the condition of the oil circuit and replace the oil filter — proper lubrication is critical to turbo longevity.
• Verify the cleanliness and integrity of the air hoses and air intake to prevent any particles from entering the compressor.
• Inspect the intercooler and air filter, which are often put under heavy stress during spirited driving.
• Prime the turbo with oil before the first start-up to ensure immediate lubrication of the bearings.
• Drive gently for the first few kilometres after replacement to allow everything to settle in.

Paying close attention to oil quality and carrying out regular oil changes will go a long way towards protecting this new turbo on your Subaru Impreza WRX GT.
