    There is no mods that would give a major power increase unfortunately. Unless you do an engine conversion of course

    Veccy C air intake and panel filter are the most common first mods, there are guides in the How To section. Your looking at max +10 hp from those.

    Others i would recommend are a performance manifold and full exhaust system but are expensive and wouldnt give a great increase.

    For the price you'd pay you'd be better selling the 1.8 and buying a 2ltr Turbo mate.

    Welcome mate just like others have said cat back, larger air intake and panel filter, but instead of a veccy c I'd go for one of these -

    I don't have one myself but will be getting one on payday

    Depends what power figures you want mate??.. mines 154bhp and think its quick enough for what it is and to gain this ive spent-
    £200- 200 cell sports cat, £475-rgm chip, £300-scorpion exhaust system cat back, £320-enlarged throttle body, £38-iradium spark plugs, £70-full service kit and gave it a good service. Plans are cam and timing next and manifold which hopefully get her to 180bhp at least.. unsure till its done but thats about it!! as stated theres plenty of dbilas upgrades ect but the turbo kit for 1.8 tops in around £4500 including the software, if your 1.8s low milaged ad say go for it!!..
