2023 Subaru WRX VB - FA24 Stage 2 Daily 330WHP

About This Build

The new VB WRX gets a lot of hate but the FA24 platform has serious potential. Cobb AccessPort with a MAPerformance OTS map woke it up from the factory sleepiness. Grimmspeed TMIC keeps boost consistent and the catted J-pipe gives it a deeper tone without drone. Nameless axleback rounds out the exhaust. Running E30 flex fuel via a Delicious Tuning kit and custom e-tune pushes it to a solid 330whp. The FA24 responds incredibly well to ethanol.
