My 92 305 TBI is completely stock. I want to a few upgrades to it so it can roll w/ the stangs come summer. I dont know what size pipes come w/ the TBI. Can anyone tell me if they are 2 1/2" or 3". I am planning on getting flowmaster catback and mufflers. What kind of headers are good? Intake Manifold? Throttle Body? Gears? Let me know any suggestions you experienced camaro owners have. I would appreciate it. Thanks!

 

2.5" or 3" in your wet dreams we get v6 exaust so our v8s come in below both TPI engines. We get 2-1/4". I say I have 190HP with just rear section exaust, cold air, and an open element. If you get full exaust you'll be at your goal easy. That's still only low 15s high 14s. Gears will help too. You got auto or stick?

Pick up a cat-back exhaust, headers, either open-element K & N or a custom cold/ram air intake, Edelbrock Performer TBI intake manifold, underdrive pulleys (unless you have a system), an Ed Wright or JET computer chip, and make your fuel pressure regulator adjustable...oh, and work on the ignition (MSD and wires). Then you'll have over 230 HP.
