Upgrading your turbo is one of the best HP increasing modifications you can make for your WRX/STI.  Also, selecting a turbo with the best components is essential to getting the most out of your investment.  SteamSpeed Turbocharges combines the best in advanced compressor and turbine aerodynamics with OE quality manufacturing to produce the STX line turbochargers.

The STX line of turbochargers from SteamSpeed feature Garrett GTX style billet compressor wheels and lightweight turbines wheels.  SteamSpeed STX compressors are able to outflow similarly sized billet compressors from others thanks to SteamSpeed’s custom made 11-blade billet compressor wheels with next generation of aerodynamics first introduced by Garrett GTX turbos.  SteamSpeed STX turbos also feature a unique low inertia 9-blade turbine design that decreases spool time and increases transient boost response and peak power potential.

SteamSpeed understands that picking the right turbo for your car is critical to achieve your goals for responsiveness and power.  The STX 71 TS is a 59 lbs/min turbo based off of the Garrett GTX3071R compressor specs in a stock-location bolt-on package.  Combined with a 9-blade TD06SL2 turbine, the STX 71 TS is perfect turbo for those looking fast-spooling response while still being capable of making 400-450 whp with supporting mods.
