I have a 2014 Subaru legacy and I love it, but id like to get some more power out of it. I have a very limited knowledge of upgrading cars, but from what I've researched and been told I think the best way to achieve the 350-400hp I'm looking for (and staying under $4-8k) is keeping the current engine and rebuilding it with forged pistons, turboing the engine and swapping the transmission. I've also been told I might need a new intercooler as well, but I haven't gotten any professional advice yet. Does this sound like a terrible idea? And what do you think the cheapest/best way to get more power in my legacy would be? Would really appreciate any advice!
