It is well known that upgrading your turbocharger with a larger SteamSpeed 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 SteamSpeed STX turbo to fit nearly every goal.
