    erm.. tbh no.
    you could spend £350 on cams and vernier pully. pay even more to get the head gas flowed and only gain wat the 1.6 16valvers are pushing out.
    now thats coming from a person who owns a 1.6 8v.

    universal one on my astra (1.6 8v) sounds just nice, little bit quiet actually, the induction kit is louder :s

    hang on, concerning cams, cams are pretty cheap on the good old 8v as you only need one, relatively easy to fit so I'm told on the older 8v engines and willmake a diff. I have only done the cams on my 2.2 and that made a real diff. Anyway my bro has calibra 8v with high lift cams and thats pretty fun. get a decent filter, decent exhaust (magnex etc not universal balls) and then cams and you'll have a happy fun go cart otherwise forget all that and either buy a decent more powerful astra or fit a turbo. I think you can even get a decent exhaust manifold too if you want to spend cash

    Anything else on cams? Wouldnt mind making my 8v a bit nippier. So is it worth it? How much does it cost and can a novice fit cams?
