    2.2 Throttle Body on a 1.8?

    OK guys, any info on acquiring the TB off a 2.2 and modding it or my car (1. so that it fits?

    I was thinking is it just a case of marking out the TB hole sizes on the manifold and cutting/grinding it away with a dremel so it fits?

    what kind of power gains do you think id get? (Ive only done the k & n filter and veccy pipe mod so far)

    wud it be worth it if i cud pick up the bits i need for say £50-£100?

    Pete
    Any info on V6 MK4 conversions greatly appreciated!

    Doubt if it would fit mate as the the induction tract is on the front of the 2.2, and on the back of the 1.8.

    IIRC Regal or Courtenay do enlarged throttle bodies for most VX engines, that's would probably be your best bet. I know the 2.2 one is about £250, but not sure about the 1.8 as I don't own one

    To a large extent, the power and torque out put on any engine is dependent on the volume of air its capable of drawing in. Research shows that the standard GM throttle bodies fitted to most Vauxhall engines are undersized and act as a bottle-neck to the inlet charge, pegging back power and torque. To over come this we dismantle the throttle body and use a CNC lathe to enlarge the diameter of the unit, as well as installing a new, bigger throttle disc and low profile spindle to suit. Typically, this results in an increase in full throttle cross sectional area of between 10 and 20%. The result? Improved torque and power outputs usually in the order of 4 to 7 bhp, as well as superior throttle response and a sharper feel to the engine. this could be done at any company with a CNC lathe for about £50 to £100 max i would say
