Drag Race GTX4502R, 52 Trim, 73.8 Inducer, 102.3 Exducer – Garrett P/N: 800269-11

Built specifically for drag racing classes that cap compressor wheel diameter at 74mm, the Drag Race GTX4502R gives serious competitors a way to maximize airflow within strict rulebook limits. This special 52 Trim configuration is engineered for racers who need every legal advantage on the strip without sacrificing the ability to run proven GT45-series turbine hardware. It’s the choice for drag applications where compressor sizing rules dictate the build, but performance still can’t be compromised.

Performance & Application

This turbo is purpose-built to meet drag race class requirements limited to a 74mm compressor wheel, making it a direct fit for competitors racing under those class rules. Because the turbine side mates to any GT45 series turbine housing, builders can pair it with the housing configuration that best suits their power and spool targets. The compressor housing shares the same style as the GT42, so this unit is externally interchangeable with an existing GT42 turbo setup — simplifying swaps for racers upgrading from GT42-based systems.

Compatibility & Fitment

• Compatible with any GT45 series turbine housing
• Externally interchangeable with existing GT42 turbo setups

Frequently Asked Questions

Why is this turbo built with a 52 Trim, 73.8mm inducer?

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

Does this turbo come with a turbine housing?

No, this turbo has no turbine housing included, but the turbine side will mate to any GT45 series turbine housing.

Can I swap this onto an existing GT42 turbo setup?

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

What other Garrett part numbers apply to this turbo?

In addition to Garrett P/N 800269-11, this turbo is also listed under P/N 800269-5011 and P/N 800269-501S.

For drag racers boxed in by a 74mm compressor wheel rule, the Drag Race GTX4502R delivers a class-legal solution without forcing a compromise on housing flexibility or setup familiarity.
