Thread: TBI Performance

  1. #1

    Default TBI Performance

    I have a 95 chevy with a 5.7 TBI i am trying to get some sugustions for performance parts for a tight budget. The engine is completely stock i have not been able to do anything yet but want to start uprading. I am looking to try and get about 50 to 60 horses without spending an arm and a leg to get it any sugestions on performance upgrades?

    Hmmm, well for starters you could go with a TB spacer.

    Not sure what you consider an arm and a leg, but you could also go with Roller rockers.
    It's a minimally invasive project that you can have done in a day, and will build some nice HP.
    Of course headers are a popular option as well.

    Have you done anything to the vehicle so far, or is it bone stock?

    There's stuff out there for the TBI motor, just not as many as you would like.

    If you're on a budget, flipping the lid on the stock intake is a good way around getting more air into the motor.

    Read everything on here about their tuning and parts. They made respectable gains on a 5.7 tbi truck spending minimal $. Worth the read. It's also where I got my bored throttle body on my 4.3
