The GT-K 600 with billet compressor wheel is the first turbocharger in our new lineup of billet compressor wheel based GT-K turbos. This unit features a 61mm (HPC-61) billet compressor wheel for exceptional performance when only the best will do. Our forged billet HPC compressor wheels provide even greater efficiency and flow and are designed to withstand extreme pressures. Each HPC compressor wheel is machined from forged blanks and have stronger blades and wheels hubs to provide you with the maximum airflow while minimizing the rotating mass. This unit also features our F1-62 (62mm) turbine wheel to provide for a quick and efficient 600 HP. As with all of our GT-K models this unit ships standard with our patented ceramic ball bearing system and optional water cooling available.
