Hi I have recently purchased my first impreza and first impressions great! I also own a 300zx twin turbo manual running 430 bhp, my impreza has a dyno sheet showing 327 bhp. It's a 2003 sti uk with Pro drive. I want to get rid my 300 as the subaru is a nice compromise, not as quick but better on fuel more space and hopefully less tinkering ( iv replaced clutch, wheel bearing, timing belt and water pump and alternator in last month on my 300) my question is I'd like a little more power out my scooby, not massive but around 350 ish , other than exhaust and the pro drive upgrade I have no idea what mods have been done, would a remap be worth while or an Intercoller upgrade? I know cars well but nothing really about imprezas so and advice guidance be appreciated thanks
