    Astra SXi 1.6 Tune up

    Hi everyone

    I've been looking through all sorts of car mags to see what performance modifications I can do to a 1.6 SXi. I hav the Z16XE engine in mine and cannot find anything really to boost its performance. Does anyone know if there is anything out there that I can buy for this engine?

    Cheers

    jamesk - is your induction kit a open cone or a fully enclosed one with the cold air feed from the front?

    BK it all depends on how much your willing to spend and whether your insurance company will accept the engine mods, check first before you spend money.

    Mods

    Dbilas Inlet manifold-- around 25bhp extra but expensive at over £1000
    Lexmaul 4-2-1 exhaust manifold incorporating 200cpi sports CAT-- around 10bhp but costs around £600-800 depending where you shop
    Kent/Piper cams £500ish-- IMO about 10bhp as well but a much smoother power curve and an increase in torque
    GOOD quality stainless steel exhaust system £300-400-- only about 5bhp but worthwhile as it saves you replacing the exhaust system some years later.
    Unichip remap £500-- only get this done when you've done all the above as you need to do this step last to get the best benefits.
    52 Astra G 1.8, 18" Mille Miglia alloys, 325mm Brembo 4 pot conversion, Coupe leather interior, Raid strut brace, Whiteline rear ARB, Irmscher bits (skirts, Carbon steering wheel, Bonnet extension, M3 mirrors, boot & roof spoiler), Reiger Rear Diffuser & Front Bumper, Koni Adj. dampers, 35/30 Vogtland springs, Duplex quad exit ASCAR stainless exhaust.
