Turbocharger, Garrett G30-770, REVERSE ROTATION, 1.01 A/R O/V, V-Band In/Out, P/N 880698-5009S

The Garrett G30-770 reverse rotation turbocharger is engineered for high-performance builds where housing orientation and packaging flexibility matter as much as raw output. Built for enthusiasts and shops running custom or tight-clearance turbo layouts, this reverse-rotation configuration delivers Garrett’s proven G Series performance with the mounting versatility that reverse rotation platforms demand. It’s the right choice for builders who need a genuine, race-proven G30 core matched to a V-band turbine housing for simplified, leak-free installation.

Performance & Application

This G30-770 reverse rotation unit is built around Garrett’s G Series compressor and turbine wheel architecture, pairing a 4-inch compressor inlet with a 2-inch outlet housing for strong airflow characteristics suited to serious power builds. The V-band turbine housing inlet and outlet simplify manifold and downpipe fabrication while maintaining a secure, leak-resistant seal at high boost and exhaust gas temperatures. Reverse rotation makes this turbo particularly well suited to custom installations, twin-turbo setups, and platforms where compressor and turbine orientation must be mirrored from a standard G30-770. This configuration is intended for builders executing precision, high-output turbo system designs.

What’s Included

• Oil Feed (1mm) Restrictor Fitting to -4AN
• Two Coolant Fittings to -6AN
• Turbine Housing Inlet & Outlet V-Band Clamps
