Tomioka Racing GTX2971R Twin Scroll Turbo Upgrade
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.
NOTE: This turbocharger requires the usage of twin scroll headers and downpipe.
