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.

TR’s turbo offers a billet compressor wheel and larger wheel compared to the factory turbo. The increase in diameter is further matched with larger porting of the interior of the factory-sized compressor housing. From the outside, it looks like a factory turbo but rather it has improved airflow from the larger 60mm wheel diameter and longer 30mm wheel-blade to extract more power from the N20\/N26, achieving more effective boost. There is no core exchange required for this turbo. This is 100% bolt-on and balanced replacement turbo with improved performance over the factory turbo. This is a perfect turbo upgrade for users who are looking to get more kick from the N20\/N26 motor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e* Note: This turbo only fits vehicle with Pneumatic
