The engine is rated at 140hp from the factory
power at the wheels after drivetrain loss can range from 110-120hp in stock trim. You start adding parts and you can gain hp in small increments up to around 135whp for a manual with bolt-ons and tuning. If you want more power than that you're gonna need to go turbo or N2O.
135whp translates to approx 160hp at the flywheel.
