The Drag Race GTX4202R is a purpose-built compressor upgrade for drag racers competing in classes that cap compressor wheel size, giving teams a way to extract more from a GT42-based platform without breaking class rules. Supplied as a turbine-housing-less unit, it’s designed for racers who already run a GT42 series turbo and want a drop-in upgrade path. This is a serious component for competition builds where every millimeter of compressor wheel size is regulated and performance still has to be maximized within those limits.

Performance & Application
This GTX4202R is engineered specifically to meet drag racing class requirements that limit competitors to a 72mm compressor wheel, making it a targeted solution for teams building within strict tech inspection rules. Because it shares the same compressor housing style as the GT42 and is externally interchangeable with an existing GT42 turbo setup, it slots into current builds without requiring a full system redesign. It’s the right choice for racers who need to stay compliant with compressor wheel size restrictions while still leveraging Garrett ball bearing technology for competition-level response.
Compatibility & Fitment
- Turbine side mates to any GT42 series turbine housing
- Externally interchangeable with an existing GT42 turbo setup
- Shares the same compressor housing style as GT42
