The Garrett GTX4294R 52 Trim is a race-class compressor wheel package engineered specifically for competitors racing under a 68mm compressor wheel restriction. Built for drag racing and class-legal competition applications, this turbo delivers Garrett’s proven GTX-series compressor technology in a configuration that satisfies strict tech inspection rules without sacrificing the ability to run a full GT42-series turbine setup. It’s the choice for racers who need maximum compressor performance within a fixed wheel size limit while retaining flexibility on the turbine side.

Performance & Application

This GTX4294R is purpose-built for race class competition where a 68mm compressor wheel limit applies, making it a direct fit for import face-off and drag race class-legal builds. The compressor housing carries the same styling as the standard GT42 series, meaning it slots into existing GT42-based setups without reworking the intake side of the install. On the turbine side, this unit is supplied without a turbine housing so racers can select and match whichever GT42 series turbine housing best suits their exhaust manifold, backpressure targets, and spool characteristics. This is a component for builders who are already deep into GT42-platform turbo systems and need a class-legal compressor solution that bolts into that ecosystem.

Compatibility & Fitment

• Turbine side mates to any GT42 series turbine housing
• Compressor housing style matches the standard GT42, allowing external interchangeability with an existing GT42 turbo setup
