Drag Race GTX4502R, 55 Trim, 75.8 Inducer, 102.3 Exducer – Garrett P/N: 800269-12

The Drag Race GTX4502R is purpose-built for competitors racing in classes that cap compressor wheel size at 76mm, giving drag racers a way to extract maximum flow without breaking class rules. Engineered by Garrett for teams that need a drop-in upgrade path from existing GT42 turbo systems, this bare compressor-side unit is the choice for racers who demand class-legal performance without sacrificing top-end capability.

Performance & Application

This GTX4502R is designed specifically to meet class requirements limited to a 76mm compressor wheel, making it the go-to solution for drag racers competing under those restrictions. Built on Garrett’s GTX45 platform with ball bearing technology, it delivers the flow characteristics competitive teams need while staying within a strict wheel size limit. Because the turbine side mates to any GT45 series turbine housing and the compressor housing matches the GT42 style, this unit is externally interchangeable with an existing GT42 turbo setup — allowing racers to upgrade compressor-side performance without reworking their entire turbo system.
