    Bigger Throttle Body

    hey there
    im trying to get the best out of my X16XE (corsa) and was wondering if its possible to fit a throttle body from a x18 or x20
    would it give any gains or are they the same size?
    thanks

    Anthing os possible if you make up an adaptor plate, but you really want a mechancial throttle from the X20XEV or larger engine to be comaptibe with your Corsa which will also ahve a mechanical throttle.

    I have a spare X20XEV throttle of you need one

    You can but try, but a larger diameter TB does not always mean more power, so you could actually lose...but until you try there's no guaranteed way of knowing, it depends how the extra TB flow fits in with the head etc..
