Stage 2 FA20 BRZ: naturally aspirated refinement on 98 RON

The factory FA20 doesn't leave much on the table from the factory, but careful ECU work can still sharpen throttle response and broaden the usable torque curve. This 2013 BRZ received upgraded injectors, a high-pressure fuel pump, and drive-by-wire recalibration to support a cleaner map on 98 RON.

Dyno results showed 106 kW at the wheels, up from 103 kW stock, with torque lifting from 150 Nm to 163 Nm. The real benefit is in the delivery: smoother tip-in, better mid-range pull, and less of the flat spot that owners know well. Boost control and solenoid hardware is listed, though this platform remains naturally aspirated as delivered.

This file suits street use where drivability and fuel quality matter more than headline numbers. The FA20 responds well to fuelling precision and ignition timing refinement when the supporting hardware is in place.

Common questions
Why does the mod list mention boost hardware on a naturally aspirated car?

The FA20 BRZ is naturally aspirated from the factory. The boost control and solenoid references likely indicate hardware fitted in preparation for future forced induction, or may reflect an error in the supplied mod list.

Is 3 kW a realistic gain for a Stage 2 NA tune?

Yes. The factory FA20 is well optimised, so gains come from improved fuelling, ignition timing, and throttle mapping rather than unlocking hidden power. The 13 Nm torque lift is where the difference is felt on the road.

What does Stage 2 mean for this platform?

Stage 2 here covers ECU calibration with supporting hardware: upgraded injectors, high-pressure fuel pump, and drive-by-wire tuning. It's a step beyond a flash tune but stops short of forced induction or internal engine work.
