Performance & Application

The GT2052 is designed for builds targeting over 200 horsepower where a compact, internally wastegated turbocharger is preferred. Its journal bearing CHRA and oil-cooled design simplify installation on applications where water lines aren’t practical or desired. With two compressor wheel trim options available, this turbo can be matched to the specific flow and response characteristics a given build demands. The small frame construction makes it well suited to applications where packaging space is limited but a genuine performance upgrade is still required.
