GTX4202R 55 Trim Compressor Housing

The Garrett GTX4202R 55 Trim is engineered specifically for drag racing classes that cap compressor wheel size at 76mm, providing competitors with the largest legal wheel available. This unit utilizes Garrett's proven GTX-R ball bearing system, known for its performance and reliability. This turbocharger is a housing-only design, meaning the turbine housing is not included but it is designed to mate with any GT42 series turbine housing. It shares the same compressor housing style as the standard GT42, allowing it to drop directly into an existing GT42 turbo setup without requiring a turbine housing swap. This makes it an ideal choice for racers who have already invested in a GT42 platform and need to extract maximum class-legal airflow while maintaining external compatibility. Key specifications include a 55 Trim compressor wheel with a 75.8mm inducer and a 102.3mm exducer. The compressor housing style is the same as the GT42, and it is externally interchangeable with existing GT42 turbo setups. This product is built to meet class requirements that limit competitors to a 76mm compressor wheel.
