I have a 2011 wrx and I have been digging around for some answers and couldn't find anything. I want to get my car to around 300-320-340 wheel horsepower. I wanna know if the stock 5 speed can handle it. What parts would fail first? I already have a cobb ap. I was looking at maybe doing a turbo back invida exhaust with a catted down pipe. May be an intake? Is that amount of horsepower possible without a bigger turbo? Bigger intercooler/ front mount? Im going to do it in stages so what would be the best thing to buy first?
