interesting read. I never knew NA engines had such little gain with aftermarket parts and tuning. My stage II wrx was a big difference in power with such little $$$... If a factory turbocharger comes out later thatd be my approach... It seems as FI is the only way to reach 250 whp (which is where id like to be some day). One thing for sure though I am keeping power mods minimal and am going to let others do the experimenting. Really makes me wish they had used an H6 for this car. oh well.
