In the case of your WRX, the EJ20 includes a turbocharger and, dependant upon the design year, as many as 268 horsepower.
With improvements in turbo know-how, these engines present a major overall performance boost when keeping fuel effectiveness.
These engines could be determined by clean valve addresses, plug potential customers along with a wasted spark coil in the middle of the intake manifold. Additionally, the inlet manifold could be bare aluminum for all WRX types and crimson for all STI versions.
