i believe it CAN NOT be
i believe it CAN NOT be boosted that would ruin the platform trust me, people that want to boost these will proceed to do so (to refrane character people are supercharging them alot more than turbocharging them) and an extra 50-60hp would be highly possible....the aftermarket can have you atain 300whp on a na set up if your willing to invest a little over 10k into your engine...a new wrx sti can cost 10k plus what a brz is selling for...so please subaru do another great thing and dont add boos keep it na save weight if possibel upgrade the tires brakes suspension...and youll make a cayman, z4,slk, miata killer!
