    About to put in a 1.4 ABD into my mk2, will be running gsxr600 carbs. Before I get it set up properly Ill be putting a better exhaust on it. Ive got a modified 4 branch (to fit over subframe) to go on and potentially a 2.25 miltek with just a rear box from a mk3 VR that I can adapt to fit, however Im not sure if this is gonna be too big a diameter for the little 1.4? And AFAIK carbs need back pressure ideally?

    Hi and welcome to the forum.

    2.25 will be fine.
    The engine will be ~ 140 to 150bhp if you are lucky. So Mk2 Golf 16v power levels.
