The Drag Race GTX4202R is purpose-built for competitors racing in classes that cap compressor wheel size at 74mm, giving teams a way to maximize flow within that strict limit. This is a bare compressor/center housing assembly without a turbine housing, designed for racers who already run a GT42 series turbine housing or plan to source one separately. It’s the choice for drag racers who need class-legal compliance without sacrificing the performance ceiling that a Garrett ball bearing core delivers.

Performance & Application

This GTX4202R is engineered specifically to meet class requirements limited to a 74mm compressor wheel, making it the go-to unit for drag racers competing under that regulation. Because it’s externally interchangeable with an existing GT42 turbo setup, teams can swap into this platform without reworking their existing GT42 plumbing or mounting. The turbine side is designed to mate to any GT42 series turbine housing, giving racers flexibility to pair it with the housing configuration that suits their specific application. This is a compressor-and-core solution aimed at drag racing programs already built around the GT42 platform.

Frequently Asked Questions

Does the GTX4202R come with a turbine housing?

No, this unit is sold with NO TURBINE HOUSING. The turbine side is designed to mate to any GT42 series turbine housing.

Is this a ball bearing or journal bearing turbo?

The GTX4202R uses dual ball bearings.

Why is the compressor wheel size specifically 73.8mm inducer?

This turbo is built to meet class requirements that are limited to a 74mm compressor wheel, so the 52 Trim wheel with 73.8mm inducer is designed to comply with that limit.

Can I swap this into my existing GT42 setup?

Yes, the GTX4202R is externally interchangeable with an existing GT42 turbo setup and shares the same compressor housing style as GT42.

For drag racing programs bound by 74mm compressor wheel class limits, the GTX4202R delivers Garrett ball bearing performance in a package engineered to comply without compromise.
