    Astra AH sri turbo performance mods

    What are some mods that I could do to my astra sri turbo Z20LER? So far I got a 3" exhaust system.
    Is it worth get a cold air intake or just a k&n filter for the stock intake?
    Strut braces maybe?
    Want to eventually get it custom tuned to 98 octane. I'm in Sydney so would you guys please also recommend a good tuner for the astra?
    Say max spend around $3.5k including tune.
    Any advice on how I can be most cost effective??
    ps I'm new to the forum and have just bought the car so...hello and thank you all in advance for your input. Click here to enlarge

    would certainly be going for the whiteline rear roll bar , makes it handle much better. Would also say to get the diesel air box and k&n filter for it as it gets rid of the crossover pipe ( wish i knew about it earlier ) and get the eds ipf flashtuner .

    I haven't refuelled yet. Will use vpower. I want to custom tune @ 98 after few mods. This will maximise my power gains.

    I would do some research on what's required to get some gains
    IPF would be your best bet on the tune

    A front mount intercooler will give you a nice gain. I gained 16 kW on my SRi T

    No need to tune your car specifically for 98, you can always use that fuel, it'll run smoother if you do. Get an ipf, will give you exactly what you're after straight away.
