    Question What throttlebody to buy?

    I am looking into getting a new throttlebody and can't make up my mind.
    I like the BBK 80mm, the FAST 78mm, and the Edelbrock 80mm. Which would be the way to go.

    Not worth the $. You will make the same power, which is very little, with just porting the stock throttle body. You should save for a fast 90/90 setup.

    This is one of the many newbie mod mistakes. slp smooth bellow and slp maf are two other newb mistakes.

    you car is not making enough power to need a larger TB.

    Save your money or put it towards another mod, like an underdrive pulley (good for about 10rwhp)

    Save even more money and port your TB your-self. If your a decent mechanical/good with tools, you can do it.

    I ported mine useing a dremel tool and 1000, 1600 and 2000 grit sandpaper, and it took about 2 hours and very simple.
