Built for enthusiasts chasing serious top-end power without sacrificing drivability, the Garrett GT3582R pairs a ball bearing center section with an anti-surge compressor housing and a T4 undivided turbine housing for broad, usable boost across the RPM range. This turbo is the go-to choice for high-horsepower LSX and other performance builds that demand a proven, high-flow platform. Whether you’re building a street car with serious headroom or a dedicated track machine, the GT3582R delivers the flow capacity to back it up.

Performance & Application

The GT3582R is engineered for builds targeting 650HP and beyond, making it a strong fit for GM LSX platforms and other high-output performance applications. Its ball bearing core reduces spool lag and sharpens throttle response compared to journal bearing designs, while the anti-surge compressor housing extends the usable map for stable boost delivery under varying load conditions. The 0.63 A/R T4 undivided turbine housing with a 3″ GT V-Band outlet is tuned to balance quick spool with strong top-end flow. This combination makes the GT3582R well suited to enthusiasts building serious street or track setups who need both response and high-horsepower headroom.
