Overview

The KDM Tuners K03 Upgraded Turbo is a performance turbocharger designed to increase horsepower and efficiency over stock units. It features a 49mm 9-blade compressor wheel and a 45.5mm 9-blade lightweight turbine, along with a 360-degree bearing kit and larger surface thrust collars for enhanced durability and performance.

This upgraded turbo promotes more power by lowering Intake Air Temperature (IAT) and has been shown to decrease turbo lag compared to stock. The product boasts an average of 80 wheel horsepower (whp) gain over stock. Dyno results have shown up to 358.9 whp and 331.1 wtq with an automatic transmission using 91 octane fuel and no meth injection.
Show original supplier description
The KDM Tuners K03 Upgraded Turbo represents a significant performance enhancement over factory turbochargers, designed for enthusiasts seeking increased power and efficiency. KDM Tuners has been refining turbo upgrades since 2013, developing this popular option that boosts horsepower without compromising responsiveness, and in many cases, even reduces turbo lag. This turbocharger features a precisely balanced assembly with a 49mm 9-blade compressor wheel and a 45.5mm 9-blade lightweight turbine. It is equipped with a 360-degree bearing kit and larger surface thrust collars, contributing to its durability and improved performance characteristics. These upgrades make the turbo much more efficient than stock, leading to a reduction in Intake Air Temperature (IAT), which in turn promotes greater power output and reduces stress on the engine system. On average, users can expect an 80 wheel horsepower (whp) gain over the stock unit. The K03 Upgraded Turbo is designed to provide a daily driving experience similar to the stock turbo until the accelerator is engaged, at which point its enhanced performance becomes apparent. Dyno testing has recorded impressive results, with one instance showing 358.9 whp and 331.1 wtq on an automatic transmission vehicle running on 91 octane fuel without methanol injection. The product requires selection of the correct chassis from the available options, which include various models of the Veloster Turbo, Forte SX, Kia Soul, Elantra Sport, and Kona, all equipped with the 1.6T or Gamma engine. Please note that there is a potential lead time of 2-4 weeks for this item.
