Fitting a bigger turbo is almost guaranteed to give your car a bhp boost, or certainly the potential to make more power. But it’s not often a simple case of bolting on a new blower and forgetting about everything else; to optimise the performance potential of that new turbocharger a few other upgrades are usually needed along the way too.
While the turbo upgrade steals the limelight, little thought is given to the supporting mods. But the truth is, they are equally as important. Without them, your shiny new turbo won’t work as well as it should.
