Performance & Application
This GTX4202R is built specifically to meet class requirements that restrict compressor wheels to a 70mm inducer, making it the go-to solution for drag racers competing in these regulated classes. Because it shares the same compressor housing style as the GT42 and remains externally interchangeable with existing GT42 setups, it allows for a seamless swap without reworking surrounding hardware. The turbine side is designed to mate to any GT42 series turbine housing, giving racers flexibility in tailoring turbine-side characteristics to their specific application. This turbo is intended for dedicated drag racing applications where class-legal compressor sizing and GT42 compatibility are essential.
Compatibility & Fitment
- Compatible with any GT42 series turbine housing
- Externally interchangeable with existing GT42 turbo setups
