Performance & Application

The G30-770 reverse rotation turbo is built for high-performance engine platforms where a reverse-spinning compressor and V-band turbine housing simplify complex piping layouts. Its wheel geometry and turbine A/R are configured to deliver strong response while supporting demanding boost requirements. This turbo is suited to builds where precise packaging and V-band connections at both the turbine inlet and outlet are priorities. The reverse rotation design allows for cleaner integration into custom manifold and compressor housing orientations.
