Performance & Application
The GTX4202R is engineered for high-horsepower applications where a large frame turbocharger is required to sustain over 1,100HP. Its ball bearing core supports quick spool response for a turbo of this size, while the built-in ported shroud compressor housing helps manage surge under aggressive boost conditions. The T4 divided turbine housing is suited for applications benefiting from separated exhaust pulses feeding into a common turbine inlet. This turbocharger is intended for high-flow, high-output builds where large compressor and turbine wheel sizing is necessary to reach elevated power targets.
