Introducing the twin scroll GTX2971 for Subaru 02-07 WRX and 04-18 STi! Just like the GTX2971R,this twin scroll edition features a ball-bearing cartridge, billet compressor wheel , and 10cm2 housing. Thanks to the billet compressor wheel the overall weight of the wheel is lighter than competing turbochargers and allows for maximum airflow throughout the unit with the help of point milling on each blade. A unique wheel and blade design, featuring a 20% larger wheel with 17% longer blades than the factory turbocharger. In addition, the GTX2971 features a port and polished exhaust housing to minimize exhaust flow turbulence. All hardware is included with purchase.

 

This is the ultimate replacement for Twinscroll VF36 VF37 and VF38 

 

TR has partnered with Motul USA to offer a free 2L can of 300V 5W30 or 5W40 with any purchase of TR turbos! Choose your oil of choice in the options and we will include it in your order!
