The MY15+ WRX is the first WRX to use the Subaru FA20DIT engine. Through our extensive Research and Development Programme using our own MY15 WRX Development car, we are able to dramatically transform this car with very significant increases in both power and torque.

Interestingly, this new model is it comes with a 6 speed manual (not the STi type) or CVT Transmission that can be used in 8 speed manual mode.

The 2 litre engine can generate more power than the current 2.5 litre STi engine when compared with similar modifications.

As the new engine design has the turbo built into the exhaust manifold, it comes on boost earlier and is astonishingly quick with a MRT Power kit.

Interestingly if you fit an exhaust and don’t have it custom tuned, the power change is very poor, (MY15 WRX poor power Dyno data here) but if you get it tuned its better (MY15 WRX custom tuned power) and if you choose a MRT power kit, you get even better results with:
