I did some research and read in one of the forums that the 2.3 HO throttle body will fit on the 2200 motor without any engine modifications. Is this true? and if so what is the diffrence between the 2.3 TB and the stock 2200 TB?
Read more into your searching. Yes the 2.3 56mm TB will fit on your car. The diff is that the 2.3 TB is bigger than your 2.2 TB allowing more air to pass through into your intake manifold. The more air the more fule the more power.
My car has two speeds, fast and faster.
