Supporting Mods
Get the airflow, cooling and chassis stiffness in before chasing more boost.
The unglamorous half of a build. An intercooler that can actually shed heat, hoses that will not go hard and split, and a strut brace so the front end stops arguing with itself, all fitted before anyone talks about a bigger turbo.
Do this half first and the car is quicker, more reliable and cheaper to take further later. Do it second and you usually pay for the same parts twice.
