Turbo? or internals
i have a 2003 eclipse RS 150k miles, i put new headers , cold air intake , short shifter, aftermarket exhaust, and a few other mods. i want more power though and im wondering if i should upgrade the head, or just turbo it. ive read a few threads and some say you can run turbo at around 8-12 psi but will that give me much more power ? or should i swap the head then turbo charge it? if so what would be a good head to swap with ? or what turbo would be good for it.
