Parts are easy to buy and easy to install badly. We fit downpipes, charge pipes, intercoolers, intakes, hybrid turbos and full single-turbo conversions, then tune for them, so the car leaves working as one system instead of a pile of brand names.

Downpipes (catted and catless), charge pipes, intercoolers, intakes, exhausts. Fitted properly, clamped properly, no rattles.
Stock-location hybrids from Pure, VTT and the like, or a big single on a manifold for the serious builds.
Forged pistons, rods, head work, upgraded fuel. For the cars going well past what the stock bottom end is happy with.
Every part goes in with a plan for the tune behind it. One shop, one conversation, one bill.
We'll ask the annoying questions, then give you a real number.
