Wanting some input, is this upgrade going to be a nice jump in power dollar for dollar or should i save for a turbo upgrade ?I am not trying to break dyno records . I just want a little more.
i have almost the exact same setup but on a s14 sr and greddy split elbow. went to 555 and z32, it was a huge jump in power from running .87 bars of boost before. with the upgrade i could run 18lbs (1.33bar) all day with a metal headgasket and arp studs. that 18lbs definately makes a big difference. i'm satisfied with it for now until i go to a bigger turbo and cams
