AVO’s big ball-bearing turbocharger for the Subaru Impreza WRX and WRX STI are true bolt-in applications. Based upon our famous Edge Series design, these turbos have been designed from the ground up to provide better reliability, performance, and response than the factory turbocharger units. All our turbochargers come with all the stainless steel water and oil fittings for the turbocharger. Also included is the famous AVO 15psi adjustable solid boost actuator, which provides for much better boost response and to maintain boost levels at higher RPM’s.
All of our ball-bearing turbochargers are water-cooled and comes with the proper oil and water lines. Our turbochargers have been designed to perform in the harshest conditions possible and have been tested in them as well. AVO products are not designed to be as reliable as OEM – they are designed to be much better than OEM. High nickel content housings ensure our turbos will go the distance. Another key performance points is the Garrett compressor and turbine wheels, which are lightweight with knife-like edges for unmatched spooling, yet built strong for reliability. An AVO ball-bearing turbocharger is likely to outlast your engine.
