It is well known that upgrading your turbocharger with a larger Steam STX turbocharger is one of the most cost-effective ways to increase power on your WRX/STI; however, it is less known that sizing the turbocharger to match your performance goals has a huge impact on how well the turbo works with your other mods, how responsive your throttle is, and how fun your car is to drive. The good news is that we make a Steam STX turbo to fit nearly every goal.

Our Steam STX 63 turbo is designed specifically for the WRX/STI owner who values a super-responsive stock-like turbo, but also wants the increased power that comes from our STX 11-blade billet compressor wheel, and the unsurpassed top-end flow

STX Standard Features:

  • Billet compressors wheel: featuring Garrett GTX style areo 11-blade wheels custom made from billet 7075 aluminum.
  • Low inertia turbine wheel: standard with 9-blade low inertia turbine wheels.  These turbines weigh 1/3 less than standard wheels significantly increasing the responsiveness, low-end torque, and top-end power.
  • Thrust bearing: CHRA built to last with heavy duty thrust bearings for high boost & power applications.
  • Adjustable Actuator: Adjustable actuator springs are available in our accessories section.
