The AVO550LGT is AVO's latest ball-bearing, bolt-on turbocharger solution for the USDM Subaru Legacy GT and Outback XT. It was designed specifically to be true OEM quality bolt-on solutions for the Legacy GT and Outback XT with proper oil and water cooling lines. What’s more, not only does the ball-bearing design enhance response and spool times, it is more reliable than the journal-bearing design used by the OEM turbocharger. Thanks to single-cartridge, dual ball-bearing technology, our turbochargers generate far less frictional drag and are 10 times more durable than traditional journal-bearing turbochargers.
