The GTX4502R is a purpose-built 67mm drag race turbocharger from Garrett’s GTX-R series, engineered for competitors chasing four-digit horsepower numbers at the strip. It’s built for racers who need a compressor wheel pushed to its absolute limit while paired with a high-flowing turbine side to keep backpressure in check. If your build demands massive top-end power without compromising the ability to spool, this is the class-dominating choice.
