tuning
Can I run E85 or an ethanol blend in a 2022+ WRX?
Not on the stock tune. The VB is not flex fuel from the factory, so ethanol needs a flex fuel sensor and a tune written for it. Done properly it is the best power per dollar on the platform.

reliability
How much power can the stock FA24 engine handle?
The short block is generally considered safe to around 400whp, with real caution beyond 400 to 450. But you will hit the stock turbo around the low 300s and the stock transmission's torque limit well before the engine becomes the problem.
