    theres not really a limit to what can be achieved with the mk4 gsi...theres lots of stuff out there and many companies that specialise in tunning vauxhall's as you prob already know.
    you can get a decent bit of power from not alot of outlay but running the zlet and zleh turbo will always limit what you can do.my advise is if your serious about running some decent power is save some money back then get aload of work done in one go.
    that being said you can get a nice bit of extra power just from fitting a decent full exhaust system a fmic and remap..
    your in the right place anyway theres every sort in here..people running standard up to all out 400+ builds..
    ive just had a load of work carried out on my gsi and should be running around the 400 mark quite soon.

    Lmf or Vauxhall for parts mate...

    I would get a turbo back, coilovers, remap for a nice gain for now mate after that u need the Vxr turbo and front mount intercooler to get Better gains then after that u need Vxr injectors and air flow meter to get to 280+bhp

    Also panel filter, iridium plugs, larger tophat alot of things mate

    go vauxhall for your parts mate, plus you get 12 months warranty on GM parts. Some of LMF parts are not GM. If you need any parts mate PM as i work for vauxhall parts and do cheap price for GM parts and can also post!

    Depends on how you want to start off really. i have no desire to run any higher than stage one, hence i have

    Chrome boost pipe
    Cat-back stainless exhaust
    cossie plugs (or iridiums)
    standard zlet turbo

    Nothing much else really, might spend some more cash at a later date though
