Garrett Advancing Motion is the OE turbocharger supplier to Porsche, BMW, Mercedes-Benz, GM, and Ford — and the choice of NASCAR, IndyCar, and Formula DRIFT. Every Garrett turbo features dual ball-bearing CHRA technology and motorsport-derived compressor wheels.
The Garrett G30 turbine housing with a 1.06 A/R and a divided T4 inlet is the ultimate choice for high-horsepower builds requiring maximum exhaust flow. The divided T4 flange design helps maintain exhaust pulse energy, which is crucial for spooling larger turbochargers while still allowing for high-end power gains. This housing is engineered to handle the demands of professional-grade racing applications.
By utilizing a divided T4 inlet, this housing effectively separates exhaust pulses from different engine cylinders, reducing interference and improving the efficiency of the turbine wheel. The 1.06 A/R ratio ensures that your G30 turbocharger can operate at its peak potential, providing the necessary flow for high-boost applications without excessive backpressure. This is a must-have component for those building high-performance engines that require consistent power delivery throughout the entire RPM range. Built with premium materials to resist extreme heat, this housing is a reliable and high-performing addition to any serious turbo setup.
