Overview

The HKS GT III-RS Sports Turbine Kit is a performance upgrade designed for the Nissan Silvia S15 and S14 with the SR20DET engine. This kit features a downsized A/R 0.60 exhaust housing, which improves exhaust flow and enhances efficiency in the low to middle RPM range.

This turbine kit is recommended for both race and street driving due to its improved acceleration response between 3,000 and 5,000 RPM. It is capable of producing over 350 horsepower. The kit includes the GT III-RS A/R0.60 Assy with an upgrade actuator, pipes for water and oil lines, and gaskets.
