Have an 02 wrx wagon with 330hp and want to make some more power. It's got V39 turbo Subaru performance Exhaust. Tomei headers External wastegate. 3 bolt up pipe dont really much about that. Whatelse can I do to get her to 350hp or more???
I agree with the intercooler concern. I assume you upgraded fuel management system with turbo? If not I would also add an AOS, new high pressure fuel pump, fuel rails, big injectors, large volume FPR, and more spark; new boots, coils and plugs at least one step colder. All that and a good you should hit that goal
I've put an 05 5 speed in her. After the stock one broke on dyno. Mishamotor radiator with sti manifold and topmount
