    General power gain upgrades.

    Hi there!

    I've got my addiction back for buying parts for my s15.

    I just need a general idea in what's the best parts to buy and makes of parts to go with for reaching around the 350-370 bhp ish mark.

    I already have

    Aem fuel pump
    740cc deatchwerks injectors (not fitted)
    Hks air filter
    Greddy front mount intercooler
    Tomei cat-back
    Blitz downpipe

    Obviously a bigger turbo and ECU will need to be fitted but anything else I should keep a eye out for?

    If that's your current list of mods and your current target, you'll also need a method of boost control, upgraded spark plugs and an AFM or MAF corresponding to your management, unless you use a MAP management system.

    Is the target horsepower the most important thing to you? Because brakes and alignment would be top of my list to make your car quicker.

    If you're going stand-alone management then they usually come with boost control, so double check before you go out buying boost controllers you don't end up needing.

    Not always, you don't get the boost control hardware with a PFC for example. But it does come with a G4.
