Introducing the GTX2971! Featuring a ball-bearing cartridge, the GTX2971 allows for exceptionally crisp and strong throttle response just like that of its larger counterpart the GTX3076. Also packed with a billet compressor wheel, the overall weight of the wheel is lighter than other turbocharger wheels and allows for more room for air-flow. Thanks to the billet construction of the unique TR blades, durability goes unmatched, keeping the GTX2971 running through any condition.

New to the TR GTX2971 and GTX3076 turbochargers are point-milled blades, which allow for reaching in all the small places between the blades to create a surface that provides maximum flow from the wheel design. In addition, the GTX2971 features a port and polished exhaust housing to minimize exhaust flow turbulence. This turbo is perfect for users who are looking for quick spooling and running moderate boost pressures. All necessary fittings and gaskets are included with purchase.
